Expert Heating & Cooling Solutions for Columbus

When you need a trusted heating and cooling company in Columbus, Dunwoody HVAC is the company to call. We've been keeping local homes and businesses comfortable year after year, earning repeat business one job at a time. Our experienced technicians live and work in the area, which means faster response times 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 handles every kind of residential and commercial heating and cooling need. We offer fast service and give you upfront pricing before any work begins, no hidden fees, ever. Our trucks are stocked with 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 running nonstop without cooling, your furnace is short-cycling or refusing to light, or you're simply planning ahead for a system past its prime, one call to (470) 200-3365 gets an experienced local technician headed your way with everything needed to diagnose the problem quickly.

Heating and Air Conditioning Service Across Columbus

Heating and cooling around here means a wide mix of equipment: older gas furnaces on the older streets, high-efficiency heat pumps in recent construction, ductless mini-splits in additions and converted garages, and packaged units on commercial buildings. Our team handles all of it. We have years of field experience, and we know how the local climate, the age of local homes, and local code affect the way equipment performs over time.

On the residential side, we take care of everything from quick fixes, like a failed 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 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, the single best 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, retail stores, offices, and multi-unit properties, and we know that every hour of downtime costs the business. To keep disruptions short, we keep common commercial parts stocked, diagnose fast, and plan larger jobs around your operating hours whenever possible.

Quick Heating and Cooling Help in Columbus

Call us with a problem and a real person picks up, not a phone tree. The majority of calls 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 freezing night, jump to the top of the schedule. We keep the process simple so nobody is left waiting for a callback.

Here's what we see most often when something breaks at home: an air conditioner blowing warm air, a condenser that hums but won't start, a furnace that ignites and shuts off, a breaker that trips every time the system kicks on, an evaporator coil that has iced over, a condensate drain backed up into the furnace cabinet, or a thermostat that has quit. Most of them come down to a part we already carry: capacitors, contactors, igniters, flame sensors, universal control boards, and common fittings. You'll see the price up front, and that's the price you pay.

If your AC has iced over, the best 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 (470) 200-3365. A few minutes of caution can prevent a much larger repair.

Getting More Years From Your HVAC System in Columbus

A little routine care makes all the difference between a system that lasts 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, at least two feet of open space around the outdoor condenser, a gentle rinse each spring for the condenser coil, and two professional tune-ups a year, so problems are found while they're still inexpensive.

Take a look at the age of your system. Its age says a lot about what comes next. Most well-maintained air conditioners reach 12 to 15 years, gas furnaces 15 to 20, and heat pumps 10 to 15. If your system is beyond that point and also shows rising bills, uneven temperatures, or frequent repairs, it's usually due for a planned replacement, and that's almost always cheaper and easier on everyone than an emergency replacement in peak season.

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.

Common HVAC Problems in Columbus

HVAC systems in this area face a familiar set of enemies. Hard-running summers push compressors and capacitors to their limits, and humidity and airborne grit slowly foul outdoor condenser coils, cutting efficiency years before the equipment should show its age. Clogged filters quietly choke off airflow, freezing evaporator coils in summer and overheating furnace heat exchangers in winter, damage that builds slowly and out of sight.

Our technicians also run into the full range of component failures in local homes: capacitors that leave the outdoor unit humming but not starting, contactors with pitted points, cracked igniters and dirty flame sensors that lock furnaces out on cold mornings, refrigerant leaks that turn into long lukewarm afternoons, and blower motors worn down by years of restricted airflow. The area's mix of older homes brings undersized returns, leaky duct runs, and rooms the original system was never designed to condition.

Every one of these problems is fixable, and most are much less expensive when caught early. If your system is doing anything unusual, strange noises, weak airflow, rooms that won't hold temperature, bills creeping upward, a quick diagnostic visit from our team catches the small problem before it becomes a costly breakdown. Give us a call at (470) 200-3365 to set up a visit.

Why Columbus Residents Choose Us

What homeowners here get with Dunwoody HVAC comes down to a few things: speed when it's urgent and thoroughness when it counts. 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 is done right on the first visit.

Your HVAC Questions Answered

Fast. We cover 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 carry the most frequently needed parts, including capacitors, contactors, igniters, and motors, so the majority of repairs are diagnosed and finished in a single visit. Call (470) 200-3365 and we'll give you an honest arrival window.
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 adds years to your equipment, helps prevent breakdowns in the middle of a heat wave or cold snap, and usually pays for itself in lower energy bills.
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 formed on the copper lines, shut the system off so the compressor isn't damaged and call us at (470) 200-3365. We'll get a technician headed your way as quickly as possible.
There's no single cutoff, but some guidelines help. Most part failures on systems under about 10 years old are worth the repair. Past the 15-year mark, or after a compressor or heat exchanger failure at any age, replacing the system usually makes better financial sense, especially with the efficiency gains newer equipment offers. We'll give you both numbers honestly and let you decide, because we'd rather earn your trust than sell you a system you don't need yet.
It depends on the job. Repairs usually come in between $150 and $650, depending on the part that failed and the type of system. A full replacement generally costs around $5,000 to $12,000 installed, depending on size and efficiency rating. Before we begin, you'll get a clear quote based on the diagnostic, and that number doesn't change.
In many cases, yes. Ductless systems shine in room additions, converted garages, sunrooms, and older homes that were built without ducts. The process 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 air would be the better fit for your home, we'll let you know.
The brand name on the cabinet rarely matters. Our technicians work on Carrier, Trane, Lennox, Rheem, Goodman, York, and the other major names you'll find around here. On the ductless side, we see a lot of Mitsubishi, Fujitsu, and LG. Most repairs use universal parts that ride on the truck, and factory parts can be sourced quickly when a repair calls for them.
Yes, we do both. We fix AC systems, furnaces, heat pumps, and mini-splits regardless of brand. If replacement is the better call, we handle the whole job: removing the old unit, a correctly sized new system, careful installation, and a full test of every mode. You'll have a clear quote for both paths before you commit.
