Atlanta HVAC Repair, Installation & Maintenance

Atlanta homeowners rarely call an HVAC company when things are going well. They call when the AC dies in a heat wave, when the furnace clicks but never lights, when one bedroom stays ice cold no matter what the thermostat says. Dunwoody HVAC built its local reputation on those calls: picking up the phone, arriving with stocked trucks, and solving the real problem on the first visit. From quick capacitor swaps to full heat pump installations, our technicians handle every job with upfront pricing and no pressure, and we treat your home like it belongs to a neighbor, because around here, it does.

Full-Service HVAC Care for Atlanta Homes and Businesses

Whether you own a condo, 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 have spent years working on central air conditioners, gas and electric furnaces, heat pumps, and ductless mini-splits throughout the area, and we understand the climate patterns, housing stock, and local code requirements that shape how systems perform in this area.

On the residential side, we handle everything from quick fixes, like a failed capacitor, a pitted contactor, a dirty flame sensor, or a seized blower motor, to refrigerant leak repair, complete system replacements, and ductless additions. Every new system we install is sized with a proper load calculation rather than guesswork, 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.

For commercial property owners and managers nearby, we service the rooftop units, split systems, and makeup air and ventilation equipment that restaurants, shops, offices, and apartment buildings depend on. Our commercial team understands that a hot dining room or a freezing office means lost business, so we prioritize fast diagnosis, stock common parts on the truck, and schedule work around your operating hours whenever possible.

Quick Heating and Cooling Help in Atlanta

Heating and cooling failures rarely wait for a convenient day, which is why we offer prompt, flexible scheduling for most situations. When you call, you'll reach a real person who will get a technician headed to your door quickly. Arrival 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 the kind of call we move to the front of the line.

The urgent calls we answer usually 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 every cycle, clogged condensate drains overflowing into the furnace cabinet, and thermostats that stop responding. Since our trucks carry capacitors, contactors, igniters, flame sensors, universal control boards, and fittings, the majority of these calls are wrapped up on the first trip, 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, turn it off at the service switch and call (470) 200-3365. A few minutes of caution can head off a much larger repair.

Keeping Your Atlanta HVAC System Running Longer

A little routine care makes all the difference between a system that runs for years and one that breaks down in the middle of a heat wave. Our advice for homeowners is a short list: fresh filters every one to three months, two feet of clearance around the outdoor condenser, a gentle rinse each spring for the condenser coil, and two professional tune-ups a year, so small issues get caught early.

Age matters too. Most central air conditioners run 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 climbing utility bills, rooms that never quite reach temperature, or a service call every season, a planned replacement is nearly always less expensive and far less stressful than an emergency one during the first heat wave of summer.

The earlier you report a comfort problem, the cheaper it usually is. A capacitor that's starting to fail is an easy, low-cost part to replace, yet the same part, neglected for a season, can ruin the compressor and turn a simple fix into a full system replacement. Save our number in your contacts today so help is one call away the moment something seems off in your home. Early intervention saves time, money, and miserable nights.

Common HVAC Problems in Atlanta

Most local HVAC failures give warning signs before they happen. A breaker that trips more than once, a condenser that hums louder each month, rooms drifting further from the thermostat setting, a musty smell at startup. Those are early signs of failing capacitors, refrigerant leaks, dirty coils, and duct problems, and caught early they're a quick visit. Left alone, they take out compressors and heat exchangers, the two most expensive parts in the system. We diagnose the cause, not just the symptom, so small problems stay small.

Why Atlanta Homeowners Trust Us

What homeowners here get with Dunwoody HVAC comes down to a few things: fast scheduling, honest diagnosis, and workmanship that holds up. We answer quickly, arrive prepared, and fix the cause, not just the symptom, checking the airflow, charge, and electrical conditions that killed the failed part in the first place. The price is set before work starts, and it stays put. Whether it's a same-day AC repair or a planned system upgrade, the job gets done right the first time.

Your HVAC Questions Answered

In many cases, yes. Ductless mini-splits shine in additions, converted garages, sunrooms, and older homes that never had ducts. Our approach starts with sizing each zone for the real load of that room, followed by careful placement of the indoor and outdoor units and a clean install of the line set, condensate drainage, and electrical service. If central equipment would be the better fit for your home, we'll tell you.
It depends on the job. Repairs usually come in between $150 and $650, depending on the failed part and the type of system. A full replacement typically runs about $5,000 to $12,000 installed, depending on size and efficiency rating. Before we begin, you'll get a written quote based on the diagnostic, and that number doesn't change.
Usually the same day. Emergencies like a dead AC or a furnace that won't light jump ahead of scheduled tune-ups, and we'll give you an honest arrival time when you call (470) 200-3365. Once our technician arrives, the common failure parts are already on board, so the majority of problems are fixed without a second trip.
Yes. We repair every major brand of air conditioners, furnaces, heat pumps, and ductless mini-splits. When a system is past repair, we handle the complete replacement: hauling away the old equipment, installing a properly sized new system, and testing it in every mode. You get a clear quote for each option before you decide.
Check the thermostat mode and batteries, the filter, and the breakers for both the indoor and outdoor units. If the outdoor unit hums but won't start, or ice has formed on the refrigerant lines, shut the system off so the compressor isn't damaged and call us at (470) 200-3365. We'll get a technician moving your way right away.
There's no single cutoff, but some guidelines help. Most component failures on systems under about 10 years old are worth the repair. After roughly 15 years, or after a failed compressor or cracked heat exchanger at any age, a replacement usually comes out ahead, especially with the efficiency gains newer equipment offers. We'll show you both numbers up front and let you decide, because we'd rather earn your trust than sell you a system early.
Yes, we offer seasonal maintenance for homes throughout the area. The spring visit covers cooling: coil cleaning, a refrigerant charge check, capacitor testing, and airflow readings. The fall visit covers heating: burner cleaning, a combustion check, and safety control testing. Keeping up with both visits extends equipment life, helps prevent breakdowns in the middle of a heat wave or cold snap, and usually pays for itself in energy savings.
The brand rarely matters to us. Our technicians regularly service 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 we already carry, and brand-specific components can be sourced quickly when needed.
