Two systems do most of the work in a typical home, and they're the two we repair most. Here's what to expect when you call.
Most air conditioner breakdowns trace back to one failed part: a weak capacitor, a burned contactor, a seized fan motor, or a slow refrigerant leak. We diagnose it with gauges and meters, not guesswork. Pricing is upfront, and we'll tell you honestly whether a repair is worth it on an older unit.
When the furnace clicks but never lights, lights and shuts off, or runs without warming the house, the cause is usually one component. We test the ignition, airflow, and safety controls to find it. You'll get a clear quote first, plus a safety check of the combustion and venting while we're there.
Not sure if you need professional help? These are the most common heating and cooling problems we solve in homes across the area.
Low refrigerant, a failed compressor start, or a dirty condenser can all masquerade as the same symptom. Real diagnosis beats parts-swapping every time.
AC repairFrequent on-off cycling is the furnace protecting itself from a real problem. Ignoring it risks the heat exchanger, the most expensive part in the cabinet.
Furnace repairWeak airflow at the vents points to duct restrictions, a struggling blower, or high static pressure. A tune-up finds it before it kills the motor.
Maintenance & tune-upsWe size replacements with a real load calculation, not a guess, so the new system delivers even temperatures and lower bills from day one.
System replacementA musty smell at startup often means moisture in the ducts or a dirty evaporator coil, worth addressing before it becomes a bigger air-quality problem.
Air duct cleaningAdditions and bonus rooms rarely get enough duct capacity. A dedicated ductless head fixes the problem permanently.
Mini-split installationAn HVAC system never fails at a convenient time. We schedule fast, show up on time, and arrive with the parts to finish the job.
We don't cut corners. Our team is experienced, background-checked, and fluent in every major brand, from a 20-year-old gas furnace to the newest inverter-driven heat pump.
We treat your budget like our own: fix what's fixable, replace what isn't, and size every new system to your home instead of the biggest thing on the truck.
We don't just swap the failed part. We check what killed it, airflow restriction, voltage, refrigerant charge, drainage, and correct that too, so the same failure doesn't repeat next season.

Acting quickly keeps a small failure from becoming a big one. Here's exactly what happens when you call Lafayette HVAC for emergency HVAC service.
You call (337) 434-8910. A real person picks up, assesses your situation, and books the soonest available technician.
There's no waiting around for days. A fully equipped technician pulls up to your home, often same-day, with the parts already on board to diagnose and start fixing right then.
During the visit, we test the full system. Our technician checks the parts that fail most and explains what happened in plain language.
Seasonal maintenance runs on your schedule, so you never have to think about it, to clean coils and test components before they cost you a compressor. Staying ahead of the problem lasts years longer and runs cheaper every month.
"From the estimate to the final walkthrough, the whole install was clear and professional. The crew wore shoe covers, put down drop cloths, hauled off the old equipment, and the final bill matched the quote exactly. The new system is so quiet we barely notice it running. I'd send anyone in Lafayette their way."
"Another company quoted us a full system replacement. Lafayette HVAC traced it to a failed blower motor and fixed it for a fraction of that quote. The tech said the rest of the system had years left in it. That kind of honesty is rare."
"Years of dust, pet hair, and who knows what else came out of our ducts. After the cleaning, the airflow from every vent is noticeably stronger, and my wife's morning allergies have all but disappeared. They showed us before-and-after photos of everything they pulled out."
We do more than patch the symptom. We make sure the job is done right. Every visit is backed by experienced technicians, quality parts, and a focus on fixing the cause.
Hands-on experience is the real benchmark for HVAC work. Every technician on our team has years of field experience across air conditioners, furnaces, heat pumps, and ductless systems, ensuring your home is serviced according to proven best practices.
