AC Repair & Furnace Repair in Dunwoody

Most of the calls we answer come down to two things: a house that won't cool, or a house that won't heat. Here's how we handle both.

AC Repair in Dunwoody

A dead air conditioner on a hot afternoon is the call we run most. The usual culprit is a small electrical part, a capacitor or contactor, that our trucks carry, so most AC repairs are finished in one visit. You get a clear price before any work starts, and if the system is old enough that replacement makes more sense, we'll show you both numbers.

  • AC running but blowing warm air
  • Outdoor unit humming but not starting
  • Frozen coil or iced-over lines
  • Water leaking near the indoor unit
AC repair costs and common fixes

Furnace Repair in Dunwoody

When the furnace clicks but never lights, lights and shuts off, or runs without warming the house, the cause is usually one component. We test the ignition, airflow, and safety controls to find it. We also check for the problems that matter for safety, like a cracked heat exchanger, and give you an upfront price before any work begins.

  • No ignition when the heat calls
  • Short cycling on and off
  • Blower running but the air isn't warm
  • New noises when the furnace kicks on

HVAC Problems We Solve

When Homeowners Should Call for Help

Not sure if you need professional help? These are the most common heating and cooling problems we solve in homes across the area.

AC Blowing Warm Air

Low refrigerant, a failed compressor start, or a dirty condenser can all masquerade as the same symptom. Real diagnosis beats parts-swapping every time.

AC repair

Furnace Won't Stay On

Frequent on-off cycling is the furnace protecting itself from a real problem. Ignoring it risks the heat exchanger, the most expensive part in the cabinet.

Furnace repair

Rising Bills, Weak Airflow

A system that runs constantly but never satisfies the thermostat is burning money. Seasonal maintenance restores the efficiency you paid for.

Maintenance & tune-ups

Old System, Repeat Repairs

R-22 refrigerant, rust on the cabinet, a compressor on its second capacitor, these are signs the smart money is on replacement.

System replacement

Dusty Air & Musty Smells

Dust settling everywhere within a day of cleaning, musty odors when the system kicks on, or allergy flare-ups indoors all point to the ductwork.

Air duct cleaning

Rooms That Never Get Comfortable

We size and mount mini-splits cleanly, proper line sets, condensate handling, and a tidy exterior finish, so they work as good as they look.

Fast Appointments

When the heat is out in January, hours matter. Our local technicians roll out same-day with stocked trucks, ready to repair on the spot.

We Fix the Cause

We don't just swap the failed part. We check what killed it, airflow restriction, voltage, refrigerant charge, drainage, and correct that too, so the same failure doesn't repeat next season.

Your Dunwoody HVAC Team

Local Experience That Makes a Difference

For over 15 years, Dunwoody HVAC has been a leading provider for HVAC service in this part of GA. Our locally based technicians understand the unique challenges that local comfort systems face, from the seasonal swings that work equipment hardest to coastal air that corrodes condenser coils.

Our team doesn't just swap parts and leave. We check the airflow, the charge, and the electrical supply driving the failure common to local homes and businesses. This local knowledge means faster diagnosis, fewer repeat visits, and systems that last.

Testimonials

Our Customers Speak for Themselves

★★★★★
4.8 out of 5 · 150 reviews

"We signed up for their maintenance plan two years ago and it has already paid for itself. On the fall tune-up they caught a cracked igniter that would have left us with no heat in January, and replaced it on the spot. Best subscription we have."

"Half our house was always five degrees warmer than the thermostat said. The tech rebalanced the dampers and fixed a kinked duct run, then set up a new smart thermostat and actually taught us how to use it. Every room finally feels the same."

RN
Raj N.
Dunwoody, GA

"Another company quoted us a full system replacement. Dunwoody HVAC traced it to a failed blower motor and fixed it for a fraction of that quote. The tech said the rest of the system had years left in it. You remember honesty like that."

FAQ

Your Questions, Answered

Most air conditioner repairs in Dunwoody run between $150 and $650, depending on the part. Common fixes like capacitors, contactors, and fan motors sit at the lower end, while compressor and refrigerant work costs more. If the system is beyond economical repair, full replacement typically ranges from $5,000 to $12,000 installed depending on size and efficiency. We diagnose first and give you a clear, upfront quote before any work begins.
A good rule of thumb: if the system is under 10 years old and the fix is a component, capacitor, motor, igniter, sensor, repair usually makes sense. If the compressor or heat exchanger has failed, the unit is past 12 to 15 years old, or repairs are stacking up season after season, replacement is the smarter investment. Our technicians walk you through both numbers honestly so you can decide with real information.
We offer same-day and emergency HVAC service throughout the Dunwoody area. Our trucks carry the most common parts, capacitors, contactors, igniters, flame sensors, and universal motors, so the majority of repairs are completed in a single visit. Even full system replacements are usually scheduled within days, not weeks.
For many Dunwoody homes, yes. Modern heat pumps heat and cool from a single system, run far more efficiently than electric resistance heat, and current models perform well even in cold weather. They cost more upfront than a basic AC swap, which is why we run the numbers on your actual usage and utility rates before recommending one.
Yes. Our technicians work on all major residential and commercial brands and system types, central air conditioners, gas and electric furnaces, heat pumps, packaged units, and ductless mini-splits. We carry universal parts on the truck and can source brand-specific components quickly when needed.
