Comfort in Lee's Summit shouldn't depend on the season. St. Peters HVAC keeps local homes and businesses at the right temperature year-round with responsive, experienced heating and cooling service, from quick furnace repairs to properly sized new systems. Our technicians know the housing stock here, which means we've seen how these systems fail locally and we arrive prepared, with the common failure parts already on board. One call to (636) 200-4659 and the problem starts getting solved.

Complete Heating & Cooling Services for Lee's Summit Properties
We service every type of heating and cooling equipment you'll find in local homes and businesses, from central air conditioners and gas furnaces to heat pumps and ductless mini-splits. It makes no difference whether the building is a starter home, a condo, or a storefront. Our techs understand the local weather, the age and construction of local homes, and the code requirements that apply to new installations, which pays off in the quality of every repair.
On the residential side, we take care of everything from quick fixes, like a weak capacitor, a burned contactor, a dirty flame sensor, or a seized blower motor, to refrigerant leak repair, full system change-outs, and ductless additions. Every new system we install is sized with a proper load calculation instead of a rule of thumb, so you get even temperatures and sensible utility bills instead of a unit that short-cycles itself to an early death. Seasonal maintenance visits clean coils, verify refrigerant charge, test safety controls, and check static pressure, still the most reliable way to extend equipment life.
Commercial service is a big part of what we do as well. We maintain and repair rooftop units, split systems, and ventilation equipment for restaurant kitchens, shops, offices, and multi-unit properties, knowing that every hour of downtime hurts your bottom line. To keep that downtime short, we keep common commercial parts stocked, diagnose quickly, and schedule larger jobs around your operating hours whenever possible.
When Your System Fails in Lee's Summit
Heating and cooling failures rarely wait for a convenient day, which is why we offer fast, flexible scheduling for most situations. When you call, you'll speak with a real person who will get a technician headed to your property without delay. Our typical arrival window in the area is typically within a day for urgent calls, and a dead AC in a heat wave or a furnace out on a freezing night is exactly the kind of call we move to the front of the line.
Common emergencies we handle include air conditioners blowing warm air, outdoor units that hum but won't start, furnaces that ignite and then shut down, breakers that trip whenever the system starts, frozen evaporator coils, clogged condensate drains backing up into the furnace cabinet, and thermostats that have simply given up. Our trucks carry the capacitors, contactors, igniters, flame sensors, universal control boards, and fittings needed to complete most repairs in a single visit. We provide upfront pricing every time, so you know exactly what the work will cost before we begin.
If your AC has iced over, the most helpful thing you can do before we arrive is switch the system off at the thermostat and set the fan to "on" so the coil can thaw. Running it frozen can flood the drain pan and damage the compressor. If a furnace is short-cycling or you smell something burning, turn it off at the service switch and call (636) 200-4659. A few minutes of caution can head off a much larger repair.
Getting More Years From Your HVAC System in Lee's Summit
The best way to avoid a mid-season breakdown is routine maintenance. We recommend that homeowners replace filters every one to three months, keep vegetation trimmed two feet back from the outdoor condenser, rinse the condenser coil each spring, and schedule a professional tune-up twice a year, cooling in spring and heating in fall, so small problems get caught while they're still cheap.
Take a look at the age of your system. That number tells you a lot. Most well-maintained air conditioners reach 12 to 15 years, furnaces 15 to 20, and heat pumps 10 to 15. If your system is past that point and is also showing higher bills, uneven temperatures, or frequent repairs, it's a strong candidate for a planned replacement, and that's almost always cheaper and easier on everyone than a rushed emergency install in peak season.
The earlier you report a comfort problem, the cheaper it usually is. A weak capacitor is an easy, low-cost part to replace, yet that same capacitor, neglected through a full season, can ruin the compressor and force a full system replacement. Save our number on your phone now so help is one call away the moment something sounds or feels wrong in your home. A quick call saves time, money, and miserable nights.
Common HVAC Problems in Lee's Summit
The service calls we run around here follow familiar patterns. In summer it's warm air from the vents, weak capacitors that finally quit on the first hot week, and iced-over evaporator coils. In winter it's furnaces that light and shut back down, dirty flame sensors, and igniters that fail on the first cold night. Year-round we see clogged filters choking airflow, rising energy bills from dirty coils, and ductwork that leaks conditioned air into attics and crawlspaces. All of them start small, and all of them cost less to fix early. If your system is showing symptoms, call (636) 200-4659 before the season turns it into an emergency.
