Heating and air conditioning in Lexington, SC, for homes and businesses
Every service below has its own page explaining how we diagnose it, what the visit looks like and what changes the cost.
As an HVAC company in Lexington, SC, most of our calls fall into a few groups. A no-cool or no-heat call starts with HVAC repair in Lexington: AC repair, emergency air conditioning repair in Lexington, SC, furnace repair, heat pump repair or refrigerant leak repair. When a system is worn out, HVAC replacement covers new air conditioners, heat pump installation in Lexington, SC and furnaces, sized with a load calculation rather than copied from the old label; the furnace repair and replacement page covers gas and electric heat. Comfort problems such as a hot upstairs, damp rooms or high power bills usually trace back to ductwork repair and replacement, indoor air quality services or a room that needs ductless mini split installation (see ductless HVAC in Lexington, SC). Homeowners can start with residential HVAC services in Lexington, South Carolina. Businesses and rental owners get small business HVAC service from a commercial HVAC contractor across Lexington County, and financing is available on larger jobs.

You talk to the person who fixes it
Describe the noise, the water or the warm air, and the technician who will test your system hears it first-hand. That is the point of a local HVAC contractor: no call-center script.
Options with pros and cons, no upsell
You see the failed part or the reading, hear the repair options and what each involves, get a free written estimate, and decide. Reviewers single this out more than anything else.
Fast when the system is past saving
Replacement equipment is often located and installed within days of the first call, when other companies quote a week out.
24/7 for real emergencies
No cooling with an infant at home, no heat before a freezing night, water through a ceiling: emergency calls are answered around the clock.
We trace the cause
A refrigerant leak gets found before anyone talks about adding refrigerant. A wet ceiling gets traced back to the drain, pan or duct that caused it.
Homes, rentals and businesses
Homeowners, landlords, realtors and commercial HVAC in Lexington for offices and shops, including HVAC and electrical inspections before a home sale closes.
From the first call to the cleanup: how a visit works
A warm vent or a cold radiator is a symptom, not a diagnosis. Whether it is an emergency or a scheduled replacement consultation, the steps are the same:
- Call and triage: You describe the symptom, the system type, the address and anything unsafe, such as water near wiring or a burning smell. Emergencies are sorted from scheduled replacement consultations on the phone, and you hear an honest arrival window.
- Test the system and the house: Thermostat call, electrical, airflow, temperature split, refrigerant charge, condensate drain, coils, blower, ducts and humidity. Poor airflow and uneven rooms usually lead to the ductwork, not the thermostat.
- Show you the finding: The failed part or the reading, with safety items kept separate from optional upgrades.
- Written options, line by line: Repair, replace or maintain, each with its pros and cons. A replacement quote lists the Manual J sizing, equipment and model, refrigerant, duct and electrical work, permits, startup testing, cleanup and warranty, never just one equipment price.
- Do the work: Required permits pulled, the home protected, equipment installed or repaired, then startup readings taken: airflow, refrigerant charge, condensate drainage and thermostat operation.
- Clean up and follow up: Old equipment hauled off, work area left clean, manufacturer warranty registration explained, and the first maintenance visit planned.
Should you repair or replace your system?
Age alone does not decide it. HVAC lifespan here depends on run hours, upkeep and moisture. Settle these first:
- What failed, and has the same part failed before?
- Does the system still run on R-22, which is no longer produced in the US?
- Is the house comfortable when it runs, or are humidity, noise and hot rooms part of the problem?
- What does each option include: duct changes, electrical work, permits, startup testing and haul-off?
- What manufacturer warranty covers each option, and what does it require (registration, maintenance)?
HVAC repair versus replacement in Lexington usually comes down to two lists. Repair makes sense when the failure is confirmed, the system is safe, parts are available and the house is comfortable when it runs. Replacement deserves a serious look after repeated failures, unsafe electrical conditions, flood damage, a major refrigerant problem or a system that cannot handle the heat and latent moisture of a Midlands summer. System age alone is not the trigger.
Our guide to repairing or replacing HVAC in Lexington walks through each question.
What changes the price of a repair or a new system
We do not quote a new system over the phone, because the scope decides the price. Make sure any written estimate spells out:
- Size and type: tonnage from a load calculation; central AC, heat pump, furnace, dual-fuel or mini-split.
- Efficiency and staging: the SEER2 / HSPF2 rating and whether the system is single-stage, two-stage or variable-speed.
- Refrigerant: older R-22 or R-410A equipment versus new A2L systems using R-454B or R-32.
- Ductwork: reusing, sealing, resizing or replacing attic and crawlspace ducts.
- Access and site work: attic platforms, crawlspace clearance, drain routing, electrical disconnects and pads.
- Timing and damage: after-hours emergencies, storm or flood damage, permits and disposal.
Financing is available on replacements and ductwork; compare the rate, term and total repayment before signing. New equipment carries manufacturer warranty coverage, which usually requires registration and regular maintenance. The federal 25C tax credit ended for equipment placed in service after December 31, 2025.
Central AC, heat pump or ductless: which fits your home?
| Option | Best for | Lexington considerations | Questions to ask |
|---|---|---|---|
| Repair | A sound system with a confirmed, repairable failure | Make sure the repair restores airflow, drainage and humidity control, not just cooling | What failed? Was the leak found? What does the repair warranty cover? |
| Central AC with a gas furnace | Homes with gas service and usable ducts | Attic and crawlspace ducts often leak; humid summers need enough run time to dry the air | Was a load calculation done? Are duct repairs and permits included? |
| Heat pump (or dual-fuel) | Heating and cooling from one system; the most common setup in the Midlands | Mild winters suit heat pumps; hard freezes lean on backup heat strips or a gas furnace | How will backup heat and defrost be tested? Is the electrical service adequate? |
| Ductless mini-split | Additions, bonus rooms, garages and older homes without ducts | Indoor head placement, line-set routing and condensate drainage matter | How many zones? Where do the line set and drain run? |
Under EPA refrigerant regulations, new residential and light-commercial systems built since January 1, 2025 use refrigerants under 700 GWP, mostly A2L refrigerants such as R-454B and R-32, and South Carolina sits in the federal Southeast efficiency region, where split-system air conditioners under 45,000 Btu/h must reach at least 14.3 SEER2. Ask any bidder which refrigerant and efficiency rating they are proposing and why.
Free written estimates
What should a written HVAC replacement quote include?
An HVAC replacement estimate anywhere in Lexington County should read like a checklist, not a single equipment price. Whether the job is central air conditioning installation, a new heat pump or AC installation in Lexington, SC, our estimate is free, and we write out every line below so you can hold it up against other bids. Get at least three written quotes and compare them line by line: a lower total that leaves out the load calculation, drainage work or startup testing is not a lower cost.
Prices depend on the scope, so we do not publish them. Our guide to central AC replacement cost in Lexington, SC explains what moves the number up or down.
| Quote line | What it should say | Why it matters here |
|---|---|---|
| Sizing | An ACCA Manual J load calculation (or equivalent) for your house | Copying the old tonnage can repeat a sizing mistake; oversized systems short-cycle and leave latent moisture behind |
| Equipment and model | Brand, model numbers for the outdoor and indoor units, and staging | Matched indoor and outdoor units are what the efficiency rating and warranty assume |
| Efficiency | SEER2 (and HSPF2 for heat pumps) | Southeast minimum for split ACs under 45,000 Btu/h is 14.3 SEER2; higher ratings trade cost for lower bills |
| Refrigerant | R-454B, R-32 or the refrigerant actually being installed | New systems moved to lower-GWP A2L refrigerants in 2025; older R-22 and R-410A parts do not mix |
| Ductwork | Reuse, seal, resize or replace, with the scope written out | Attic and crawl space ducts leak and sweat; a new unit on leaky ducts underperforms |
| Electrical | Disconnect, breaker and wiring changes, if any | A new system can need a different breaker size or a new disconnect |
| Condensate drainage | Drain line, secondary pan, float switch, pump if needed | Attic air handlers in humid summers overflow when drainage is skipped |
| Permits and inspection | Who pulls the permit and schedules the inspection | Replacement work is permitted through the town or county building office |
| Startup testing | Which readings are taken and handed over | Airflow, refrigerant charge and drain tests prove the install, not just that it turns on |
| Removal and cleanup | Refrigerant recovery, haul-off and disposal of the old unit | Refrigerant must be recovered under EPA rules before the old unit leaves |
| Warranty | Manufacturer parts terms, registration deadline, and any labor warranty in writing | Many manufacturers only honor the longer term when the equipment is registered |
| Payment | Deposit, milestones, financing terms | You should know what is due before, during and after the job |
How long does central AC or heat pump replacement take?
The HVAC replacement timeline depends on equipment availability, permits, any duct or electrical corrections, attic or crawl space access and the inspection schedule. Several Google reviewers had a new system running within a few days of their first call, when other companies quoted a week or more. Ask any contractor for a written schedule covering delivery, installation, startup testing, inspection and cleanup.
When is the best time of year to replace?
Fall and early spring. HVAC replacement in Lexington is easiest to plan when demand is lower and you can compare replacement quotes without a house heating up around you. A system that limped through last summer is worth pricing before the first 90-degree week. No-cooling calls in July still come first, and those are phone calls, not appointments weeks out.
HVAC installation financing in Lexington, SC: questions to ask
Financing options make a replacement manageable. Before you sign, check:
- Compare the APR, the term and the total repayment, not just the monthly payment.
- Ask when any promotional rate ends and what happens if it is not paid off by then.
- Ask whether the deposit is refundable and what it covers.
- Confirm when progress payments are due and what milestone triggers each one.
- Make sure the financed amount covers duct, electrical, drainage, permit and disposal work, not only the equipment.
- Get the labor, equipment, maintenance and financing exclusions in writing before work starts.
Warranties: what to get in writing
Keep the manufacturer warranty and any labor warranty separate. The manufacturer warranty covers parts and often runs longer only if the equipment is registered soon after installation. A labor warranty or service guarantee is the contractor’s own promise, so its length, exclusions and maintenance requirements belong on the written quote. Never authorize a major replacement from a verbal price.
Built for the Midlands
HVAC for Lexington humidity, attic air handlers and crawlspace ducts
Lexington sits in a hot, humid climate zone where an air conditioner has to remove water from the air as well as heat. A system that is oversized, low on airflow or short-cycling can bring the thermostat down and still leave rooms clammy. That is why our no-cool and comfort calls look at run time, coil condition, airflow and indoor humidity, not just the temperature at the vent.
Housing adds its own patterns. Many newer two-story homes around Lexington, Red Bank and Chapin put the air handler in an attic that bakes through July, so clogged condensate drains and overflowing pans show up as ceiling stains. Older brick ranches toward West Columbia and Cayce sit on crawlspaces where uninsulated or disconnected ducts sweat and pull in damp air. Around Lake Murray, large homes often run two systems against humidity off the water.
How do we diagnose poor airflow, uneven rooms and a damp house?
Humidity control for Lexington homes starts with measurements, not a lower thermostat setting or a new smart thermostat schedule. A house that reaches the setting but still feels clammy needs a moisture and airflow assessment, and airflow problems in Lexington homes often trace to the ducts. Crawl space HVAC problems in Lexington, SC, such as sweating or disconnected ducts, show up here first, so crawl space HVAC service is part of the visit. We check:
- Run time: does the system run long enough to pull moisture out without overcooling rooms?
- Airflow and blower: dirty coils, a restricted filter or a weak blower lower both cooling and dehumidification.
- Duct leakage: leaks in a hot attic or a damp crawl space pull humid air into the system.
- Attic and crawl space conditions: attic ventilation, insulation and crawl space moisture add heat and humidity.
- Indoor humidity readings: measured and written down before any dehumidifier or IAQ product is recommended.
Ventilation, filtration, dehumidification and duct repair solve different problems for indoor air quality in Lexington homes. ASHRAE Standard 62.2, the residential ventilation standard, treats fresh-air ventilation as its own design question, so we name which fix fits only after the readings are in.
Can a clogged condensate drain damage your ceiling?
Yes. The condensate drain carries the water your system pulls out of the air. When algae or sludge clogs it, the pan under an attic air handler overflows into insulation and drywall, or a float switch shuts the system down on the hottest afternoon. Proper condensate drain repair in Lexington, SC means testing the drain line and pan, checking the discharge point and float switch, and clearing the cause, not just mopping up the water.
The seasons set the calendar:
- March–April: Pine pollen season: filter changes, outdoor coil rinse, cooling tune-up before the first 90-degree week.
- May–September: Peak cooling: no-cool repairs, drain clogs under attic air handlers, refrigerant leak searches, fast replacements.
- June–November: Hurricane season: storm prep, surge protection, and inspections after flooding or lightning.
- October–November: Heating tune-ups: heat strips, defrost tests, furnace burners, flame sensors and carbon monoxide checks.
- December–February: Hard freezes: no-heat calls, iced heat pumps and emergency heat questions.
HVAC maintenance in Lexington, SC follows that calendar. Preventive maintenance works best as seasonal maintenance twice a year, spring for cooling and fall for heating, and plan members get priority scheduling and repair discounts. See AC maintenance for what a tune-up covers.
After a flood or a lightning strike: protect the system and the claim
The October 2015 flood swamped low ground in Cayce and across the Midlands, and Hurricane Helene in September 2024 brought down trees and power lines across the region. Homes in mapped floodplains along the Saluda River and the Congaree River carry the most risk. Water and surges damage the outdoor unit, the disconnect and the control boards first, and the damage is not always visible. Treat flood damaged HVAC equipment in Lexington County as an assessment job; the industry standard for assessing HVAC systems after water, fire or mold damage is IICRC S590:
- Keep the system off if water reached the outdoor unit, the disconnect, the air handler or the furnace.
- Photograph the equipment, model plate, waterline and any corrosion before cleanup.
- Call your insurer before damaged equipment is removed; the policy decides coverage, not the contractor.
- Have the electrical and HVAC components inspected before power is restored.
See storm and power-surge HVAC repair for what gets checked before power is restored.
Emergency checklist
What should you do in the first 30 minutes of an HVAC emergency?
No cooling in a Lexington, SC summer gets dangerous fast for infants and seniors. These steps keep everyone safe, rule out the simple causes and make the service call quicker. Do not open electrical panels, handle refrigerant lines or keep resetting a breaker. If you smell gas, leave the house and call your gas utility or 911 from outside.
Read the full AC-stopped-cooling guide- Step 1
Protect people first
Move infants, older relatives and pets to the coolest room in summer or the warmest in winter. Call 911 for confusion, fainting or other signs of heat stroke.
- Step 2
Shut off anything unsafe
Smoke, sparks, a burning smell or water near wiring: turn the system off at the thermostat, then the breaker or disconnect if it is safe to reach.
- Step 3
Check the thermostat
Right mode (Cool or Heat), a setting a few degrees past the room temperature, fresh batteries if the screen is blank.
- Step 4
Look at the filter
A gray, matted filter can freeze the coil in summer and trip a furnace’s safety switch in winter. Swap it if it is clogged.
- Step 5
Reset a tripped breaker once
If it trips again, leave it off. Repeated resets can damage a compressor or wiring.
- Step 6
Catch the water, then call
Water under an attic air handler or dripping from a vent: turn cooling off, put a bucket and towels down and call. A float switch may have already shut the system down.
Common HVAC failure signs and the safe first step
Match what you see to the likely cause, so you know what to switch off and how fast to call. A no cooling HVAC diagnosis in Lexington, SC starts from these signs. If the air conditioner is running but not cooling the house, the usual suspects are dirty coils, a frozen coil, poor airflow, a refrigerant leak or a failing capacitor, and each one is tested before any part is replaced.
| Likely cause | Warning signs | Safe first step | How urgent | What gets tested |
|---|---|---|---|---|
| Clogged condensate drain | Water under the attic air handler, a ceiling stain, a tripped float switch that shuts the system off | Turn cooling off and catch the water | Same day if water reaches a ceiling or light fixture | Drain line, pan, float switch, discharge point |
| Failed capacitor or contactor | Outdoor unit hums but the fan will not spin; warm air from the vents | Turn the system off at the thermostat; leave panels on | Same day in summer heat | Capacitor, contactor, motor amps, voltage |
| Refrigerant leak or frozen coil | Ice on the copper lines, cooling weaker each day, hissing | Run the fan only to thaw; never add refrigerant yourself | Soon; same day with infants or seniors at home | Pressures, temperature split, leak search |
| Electrical fault | Breaker trips again, burning smell, buzzing at the disconnect | Leave the breaker off | Call right away, before restarting | Disconnect, wiring, breaker, controls |
| Heat pump stuck or iced | Cold air in winter, unit encased in ice, heat strips running nonstop | Set the thermostat to emergency heat only if told to | Same day before a hard freeze | Defrost board, sensors, reversing valve, strips |
| Duct leakage or weak airflow | Hot upstairs, weak vents, damp rooms, high power bills | Replace a dirty filter; open closed vents | Book a visit | Filter, blower, attic and crawlspace ducts |
Which HVAC problems can wait until morning?
Smoke, sparks, a burning smell, water near wiring, a gas smell and flood exposure cannot wait: call right away. A clogged filter, one warm room or humidity creeping up over a few days still needs a diagnosis, but a scheduled visit is fine. A fresh filter can improve airflow, but it does not fix a frozen coil, a failing blower or a duct restriction.
What to photograph before the technician arrives
- The thermostat screen: mode, setting and room temperature
- The model and serial plate on the outdoor unit (and the indoor unit if you can reach it safely)
- Any water stain, ice on the lines, error code, scorch mark or tripped breaker
- Damage before cleanup, if a storm, flood or ceiling leak is involved
How to check out any HVAC contractor in South Carolina
Ask for the company’s legal name and license number and look it up on the South Carolina Department of Labor, Licensing and Regulation (LLR) website. Ask for proof of insurance, a load calculation on any replacement, and an itemized written quote that lists the equipment, refrigerant, duct and electrical work, permits, startup testing, cleanup and warranty terms. Puzzled Comfort Solutions LLC has been registered in South Carolina since April 2021.
Does a South Carolina HVAC contractor need a specialty license?
Yes. Under South Carolina HVAC license regulations, residential HVAC work is licensed as a specialty through the Residential Builders Commission, and commercial mechanical work through the Contractor’s Licensing Board, both part of SC LLR. A licensed contractor’s classification should match the job. Checking a South Carolina HVAC license takes four steps:
- Get the exact name and number: Ask for the contractor’s legal business name and South Carolina license number.
- Look it up at SC LLR: Search the license on the SC Department of Labor, Licensing and Regulation (LLR) website.
- Check the classification: Residential HVAC work falls under the Residential Builders Commission’s specialty licensing; commercial mechanical work falls under the Contractor’s Licensing Board. Make sure the license fits the job.
- Ask for insurance and permits: Request current proof of insurance and confirm who pulls the permit.

“Very happy I decided to go with Puzzled. Chong was very easy to talk to,understanding, informative, and quick to get started. For those reasons I trusted him to replace out HVAC unit. He was able to get me a new unit installed within 3 days of our first phone call while most companies stated they couldn’t get to me for Atleast 5-6 days. Will definitely recommend to all my friends who have AC issues.”

“Chong came to assess my HVAC for routine maintenance. After calling three others to no avail. He reached out earlier in the day to ensure we were still on and he showed up 5 mins before scheduled time. His honesty was refreshing. He explained everything thoroughly and offered suggestions but did not try to upsell me on anything. To my surprise he offered several discounts. He gained a new customer in me. Thanks again!”
“Puzzled Comfort solutions came recommended by a family member a few years ago and Chong is now our go-to person for anything HVAC and electrical related. He has saved us several times during emergency situations. Not only is Chong knowledgeable, he is trustworthy, professional, fair and efficient. During the heat of Summer, Chong came for emergency services when my HVAC went out while my nephew who was an infant was staying at my home. He fixed our issue quickly and had things up and running in no time. Recently, on Labor Day, while out of town we had a leak from our light fixture coming from the HVAC/roof. This could have easily turned into an electrical fire/problem and put my pets and house sitter at risk. Chong came out and fixed the issue within an hour and made sure our home was safe until he could get out there. I highly recommend using him for any of his services and we will now be on schedule for a bi-annual checkup to prevent further issues from happening. I have referred Chong to several friends and businesses who have felt the same about his great work. Thank you again!”

“Our upstairs AC had been down for almost a week when we were referred to Puzzled Comfort Solutions. He responded quickly, arriving on time to look at the system on Thursday afternoon. We decided to replace the upstairs AC and furnace since they were both older units and located in the attic. He located the equipment on Friday and arrived early Saturday morning for installation. Thankfully, we had cool air again on Saturday evening. New system is working well!”

Response from the owner: Thank you for the amazing review, I appreciate the opportunity to be able to get you comfortable again!
“Chong showed up on time and took a look at our system. We wanted a full duct work replacement and he agreed it was a good idea. He helped us with very easy financing. He arrived to do the job when he said he would and did excellent work. When he was done, he cleaned everything up. You wouldn't have even known he was there. Our AC works better than it ever has. We can't recommend Puzzled Comfort Solutions more. They are awesome to work with and do excellent work. Thank you very much Chong.”

What do people ask before calling an HVAC contractor in Lexington?
Who is Puzzled Comfort Solutions?
Puzzled Comfort Solutions is an independently owned heating and air conditioning company based in Lexington, SC, registered in South Carolina since 2021. We are a Bryant-authorized dealer and NATE certified, with over 10 years of HVAC experience. The owner-technician answers and runs most calls, and customers on Google mention honest advice, no upselling and fast replacements, often within days of the first call.
Do you offer 24/7 emergency HVAC service in Lexington?
Yes. Emergency calls are answered 24/7 for no cooling in summer heat, no heat on a freezing night, water coming through a ceiling, or burning smells and tripped breakers at the equipment. Arrival time depends on where you are and what calls are already open, so we tell you honestly on the phone. If anyone in the home shows signs of heat stroke or you smell gas, call 911 or your gas utility first.
Which towns around Lexington, SC do you serve?
Our home turf is Lexington County: Lexington, Red Bank, Oak Grove, White Knoll, West Columbia, Cayce, Springdale, Pine Ridge, South Congaree, Gilbert, Seven Oaks and Irmo. We also work across Columbia and Richland County, around Lake Murray to Chapin, and south to Gaston and Swansea. Farther Midlands towns are scheduled by distance. The service-areas page lists every community.
Do you work on both homes and businesses?
Yes. Most calls come from homeowners, but we also service offices, shops, churches, restaurants and rental properties, and we work with landlords, property managers and realtors who need repairs or inspections done before a move-in or closing. Commercial jobs include split systems, packaged and rooftop units, and maintenance schedules built around business hours.
Why does my Lexington home feel humid even when the thermostat reaches its setting?
Usually because the system is removing heat but not enough moisture. In the Midlands an air conditioner has to pull water out of the air as well as heat. An oversized unit that shuts off too soon, a dirty coil, low airflow, leaky attic or crawlspace ducts, or a fan left in the On position can all leave rooms cool but clammy. Lowering the thermostat rarely fixes it; testing airflow, run time, coil condition and humidity does.
Do I need a load calculation before replacing my HVAC system?
Yes, ask for one. Matching the new unit to the size of the old one can repeat a sizing mistake, and in a humid climate an oversized system short-cycles and leaves moisture behind. A Manual J style load calculation looks at the house itself, including insulation, windows, duct location and orientation, so the new system fits the home rather than the old equipment.
How much does HVAC repair or replacement cost in Lexington, SC?
It depends on what failed and what the job includes, so your HVAC estimate in Lexington, SC is free and comes after we look at the system, not as a number over the phone. Repair cost turns on the part, refrigerant and access. Replacement cost turns on the load calculation, SEER2 level, refrigerant, ductwork, electrical work, condensate drainage and permits. Every line is written out before work starts, and financing is available on larger jobs.
How often should I schedule HVAC maintenance in Lexington?
Twice a year. Book a cooling tune-up in spring, before pine pollen and the first heat wave hit the outdoor coil, and a heating check in fall, before the first freeze. Heat pump service in Lexington needs both visits, because the same unit cools and heats. Between visits, change the filter on schedule and keep the condensate drain clear; an HVAC technician should test the drain, coils, charge and electrical connections, not just look at them.
How can I verify an HVAC contractor in South Carolina?
Ask for the company’s exact legal name and license number, then look it up on the South Carolina Department of Labor, Licensing and Regulation (LLR) website and check that the classification fits the work. Ask for current insurance details, a written, itemized quote and the warranty terms in writing before you sign anything.
Is flood-damaged HVAC equipment safe to run?
No. If water reached the outdoor unit, the electrical disconnect or an indoor air handler or furnace, leave the system off until it has been inspected. Photograph the equipment, the waterline and the model plate before anything is removed, and call your insurer if you plan to file a claim. Electrical and gas controls can fail days after they dry out.
