Trusted Knoxville HVAC Service

Comfort in Knoxville shouldn't be seasonal. Memphis HVAC keeps local homes and businesses at the right temperature year-round with responsive, experienced heating and cooling service, from same-day AC repair to right-sized system replacements. 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. Call (901) 749-7931 and we'll get the fix started.

Complete Heating & Cooling Services for Knoxville Properties

Whether you own a single-family home, a rental property, or a commercial space in town, we have the expertise and equipment to handle the full range of heating and cooling work. Our technicians bring years of hands-on experience with 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 here.

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 tracking down refrigerant leaks, complete system replacements, 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 reasonable utility bills instead of a unit that short-cycles itself to an early death. Our seasonal tune-ups clean coils, verify refrigerant charge, test safety controls, and check static pressure, the single best way to extend equipment life.

For commercial property owners and managers nearby, we service the rooftop units, split systems, and dedicated ventilation equipment that restaurants, retail spaces, offices, and multi-unit buildings depend on. Our commercial team understands that a hot dining room or a freezing office means lost business, so we prioritize fast diagnosis, carry common parts on the truck, and schedule work around your operating hours whenever we can.

Fast HVAC Response in Knoxville

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 reach a real person who gets a technician headed to your property quickly. Our typical arrival window in the area is usually 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.

The urgent calls we run tend to follow a pattern. On the cooling side, it's an AC blowing warm air, an outdoor unit that hums without starting, or an evaporator coil frozen solid. On the heating side, it's a furnace that ignites and drops out. And any time of year, it's breakers that trip whenever the system starts, clogged condensate drains overflowing into the furnace cabinet, and thermostats that stop responding. Because our trucks carry capacitors, contactors, igniters, flame sensors, universal control boards, and fittings, the majority of these calls get fixed in one visit, at a price you approve before we start.

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, shut it down at the switch and call (901) 749-7931. A few minutes of caution can prevent a much larger repair.

Getting More Years From Your HVAC System in Knoxville

The best way to avoid a mid-season breakdown is simple maintenance. We recommend that homeowners replace filters every one to three months, keep shrubs and grass 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 inexpensive.

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 showing symptoms, such as climbing utility bills, rooms that never quite reach temperature, 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.

If comfort problems do show up, acting quickly keeps them small. A weak capacitor is a quick fix. The same capacitor left alone for a season can take the compressor with it and turn a minor repair into a full system replacement. It's smart to keep our number saved on your phone so you can reach us at the first sign of trouble. Early intervention saves time, money, and miserable nights.

Typical Heating & Cooling Issues in Knoxville

Ask any homeowner around here what HVAC trouble looks like and you'll hear the same stories: the upstairs that never cools, 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 see these problems weekly and carry the parts to fix most of them on the first trip.

Why Knoxville Residents Choose Us

Choosing an HVAC company comes down to trust, and trust has to be earned. Memphis HVAC earns it by recommending the $150 repair when that's what the system needs, by sizing replacements with real load calculations instead of guesswork, and by standing behind every repair long after the visit ends. We keep response times short throughout the area, and each visit wraps up with the system tested and your questions answered.

Common Heating & Cooling Questions

Check the thermostat mode and batteries, the air filter, and the breakers for both the indoor and outdoor units. If the outdoor unit hums but won't start, or ice has built up on the refrigerant lines, shut the system off so the compressor isn't damaged and call us at (901) 749-7931. We'll get a technician headed your way right away.
There isn't one magic number, but some guidelines help. Most component failures on systems under about 10 years old are worth repairing. After roughly 15 years, or after a failed compressor or cracked heat exchanger at any age, replacing the system usually comes out ahead, 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 early.
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 is far cheaper than a breakdown in the middle of summer, and lower energy bills often cover the cost of the visit.
Every major brand, including Carrier, Trane, Lennox, Rheem, Goodman, and York, plus ductless systems from Mitsubishi, Fujitsu, and LG. Our technicians carry universal parts that fit most units and can order brand-specific components quickly when a repair requires them.
For a lot of homes, yes. Ductless mini-splits work especially well in room additions, garages, sunrooms, and older homes that were built without ducts. The process starts with sizing each zone to the actual room, followed by thoughtful placement of the indoor and outdoor units and a clean install of the line set, condensate drainage, and electrical connections. If central equipment would be the better fit for your layout, we'll tell you.
We do both. Most calls start as a repair, and our technicians work on air conditioners, furnaces, heat pumps, and ductless mini-splits from all the major manufacturers. If a system can't be saved, we manage the whole replacement, from the load calculation and hauling off the old unit to installation and testing in every mode. Either way, you'll see a written quote for each option before anything happens.
It depends on what's wrong. Repairs usually come in between $150 and $650, depending on the failed part and the type of system. A full replacement typically costs about $5,000 to $12,000 installed, with size and efficiency making the difference. Before we begin, you'll get a clear quote based on the diagnostic, and that number doesn't change.
Fast. We serve the whole area with same-day appointments for most calls, and no-heat and no-AC calls go to the front of the line. Our trucks are stocked with the most common parts, including capacitors, contactors, igniters, and motors, so the majority of repairs are diagnosed and finished in a single visit. Call (901) 749-7931 and we'll give you an honest arrival window.
