Complete Comfort Care in Lee's Summit

When you need a dependable heating and cooling company in Lee's Summit, Florissant HVAC is the team to call. We've been keeping local homes and businesses comfortable year after year, building our reputation one satisfied customer at a time. Our technicians are local, not dispatched from across the state, which means shorter waits and a real understanding of the climate patterns, housing stock, and ductwork quirks that shape how HVAC systems here perform and fail.

From a single furnace that won't light to complete system replacements, ductless mini-split installations, and seasonal maintenance programs, our team takes on every type of residential and commercial heating and cooling need. We offer prompt service and give you a clear, written quote before any work begins, no hidden fees, ever. Our trucks carry the parts that fail most, capacitors, contactors, igniters, flame sensors, blower motors, and thermostats, so most repairs are finished in a single visit.

Whether your air conditioner is tripping the breaker, your furnace is short-cycling or refusing to light, or you're simply planning ahead for a system past its prime, one call to (557) 256-7420 gets a skilled local technician headed your way with everything needed to diagnose the problem quickly.

Heating and Air Conditioning Service Across Lee's Summit

Whether you own a condo, a rental property, or a commercial space in town, we have the know-how and equipment to handle the full range of heating and cooling work. Our technicians have spent years working on central air conditioners, gas and electric furnaces, heat pumps, and ductless mini-splits across the region, and we pay close attention to the climate patterns, housing stock, and local code requirements that shape how systems perform in this area.

A normal week for our residential technicians includes capacitor and contactor replacements, flame sensor cleanings, refrigerant leak repairs, blower motor swaps, plus the occasional full system replacement or ductless addition. When we do replace equipment, we size it with a room-by-room load calculation rather than matching the old unit. Right-sized equipment keeps rooms even, keeps utility bills reasonable, and avoids the short-cycling that kills compressors early. Beyond repairs and replacements, we offer seasonal tune-ups that clean coils, confirm the refrigerant charge, test safety controls, and measure static pressure, the most effective thing you can do for longer equipment life.

Local businesses receive the same attention. An overheated storefront or a drafty office costs real money, so our commercial crews focus on getting to the cause quickly and keep high-failure parts on board for rooftop units, split systems, and ventilation equipment. Restaurants, retail shops, offices, and multi-unit buildings can ask us to schedule work around their operating hours whenever possible.

Quick Heating and Cooling Help in Lee's Summit

Call us about a problem and a real person picks up, not a phone tree. The majority of service requests are scheduled the same day or the next, and urgent calls, an AC that quits in a heat wave or a furnace that fails on a bitter night, go straight to the front of the line. Scheduling stays flexible so you're not stuck waiting for a callback.

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, iced-over 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.

Two situations call for quick action from you before our technician gets there. The first is an iced-over air conditioner: switch the system off at the thermostat and set the fan to "on" so warm indoor air thaws the coil, because running it frozen can overflow the drain pan and damage the compressor. The second is a furnace that short-cycles or gives off a burning smell. Shut it down at the switch and give us a call. That small step can prevent 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 have a professional tune-up twice a year, cooling in spring and heating in fall, so small problems get caught while they're still cheap.

Age matters too. Most central air conditioners last 12 to 15 years, furnaces 15 to 20, and heat pumps 10 to 15 with regular service. If your system is past that window and starting to struggle, such as rising energy bills, rooms that never feel comfortable, or a service call every season, a planned replacement is nearly always less expensive and much easier on you than an emergency one in the middle of a cold snap.

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 for a season, can take out the compressor and force a full system replacement. Save our number on your phone now so help is one call away as soon as something sounds or feels wrong in your home. A quick call saves time, money, and sleepless nights.

Common HVAC Problems in Lee's Summit

Ask any homeowner around here what HVAC trouble looks like and the answers sound familiar: the AC that quit during the hottest week of the year, the furnace that woke everyone up with a loud bang at 2am, the system that runs all day but never satisfies the thermostat. Behind those stories are predictable culprits: worn capacitors and contactors, low refrigerant charge, crushed or leaky ducts, and years of skipped maintenance. Our technicians run into these problems every week and carry the parts to fix most of them on the first trip.

Why Lee's Summit Homeowners Trust Us

Florissant HVAC treats this community like home turf, because it is. We show up when we say we will, we diagnose before we quote, and we put real numbers on both repair and replacement so you can decide based on facts, not pressure. Our technicians are seasoned on everything from 20-year-old furnaces to inverter heat pumps, our trucks carry the parts that actually fail, and our work is tested before we leave. That's why neighbors here pass our number around.

Common Heating & Cooling Questions

Start with the simple checks: confirm the thermostat is set to cool with working batteries, look at the filter to see if it's clogged, and look for a tripped breaker on both the indoor and outdoor units. If none of that helps and the outdoor unit hums but won't start, or you see ice on the copper lines, shut the system off to protect the compressor. Then call (557) 256-7420 and we'll dispatch a technician to your home as fast as we can.
There isn't one magic number, but some guidelines help. Most component failures on systems under about 10 years old are worth repairing. Past the 15-year mark, or after a compressor or heat exchanger failure at any age, replacing the system usually makes better financial sense, and newer equipment brings real efficiency gains. We'll give you both numbers up front and let you decide, because we'd rather earn your trust than sell you a system you don't need yet.
We do, and we'll help you decide which makes sense. We fix AC systems, furnaces, heat pumps, and mini-splits regardless of brand. If replacement is the better call, we handle everything: old equipment removal, a correctly sized new system, a clean installation, and testing in every mode. You get clear quotes for both paths before making a decision.
Yes, and for most homeowners it's the best thing you can do for your equipment. Twice a year, a technician cleans the coils and burners, checks the refrigerant charge and combustion, tests capacitors and safety controls, and measures airflow from supply to return. Catching problems at a tune-up costs far less than a breakdown in the middle of summer, and the energy savings usually cover the cost of the visit.
The brand name on the cabinet rarely matters. Our team work on Carrier, Trane, Lennox, Rheem, Goodman, York, and the other major names you'll find around here. On the ductless side, we see plenty of Mitsubishi, Fujitsu, and LG. Most repairs use universal parts that ride on the truck, and brand-specific components are quick to source when needed.
Fast. We cover the whole area with same-day appointments for most calls, and no-heat and no-cooling emergencies go to the front of the line. Our trucks are stocked with the most frequently needed parts, including capacitors, contactors, igniters, and motors, so the majority of repairs are diagnosed and completed in a single visit. Call (557) 256-7420 and we'll give you an honest arrival window.
Yes, and a mini-split is often the smartest answer for additions, garages, sunrooms, and older homes built without ductwork. Every zone is sized to the room it serves. We map out where the indoor and outdoor units go and install the line set, condensate drain, and electrical work properly. And we'll be upfront if a ducted system would serve you better.
It depends on the job. Most repairs come in between $150 and $650, depending on the failed part and the type of system. A full replacement typically runs around $5,000 to $12,000 installed, depending on size and efficiency rating. Before we begin, we provide a written quote based on the diagnostic, and that price holds.
