Most Atlanta homes benefit from a cooling tune-up in spring and a heating tune-up in fall, or twice-yearly service for heat pumps. A good tune-up cleans coils, clears the condensate drain, tests electrical parts and refrigerant performance, and checks furnace safety. Between visits, change the filter regularly and keep the outdoor unit clear.
Last updated
Most no-cooling calls in Atlanta happen during the first real heat wave of the year, when systems that sat quietly all spring suddenly run all day. Routine maintenance won't prevent every failure, but it catches worn parts, clogged drains, and dirty coils before they leave you without air conditioning on a 95-degree afternoon.
When to schedule
- Cooling tune-up in spring, before the long Georgia cooling season starts in earnest.
- Heating tune-up in fall, before the first cold night, especially for gas furnaces.
- Heat pumps run in both seasons, so twice-a-year service is common.
Some manufacturers' warranties expect regular professional maintenance. Keep receipts in case you ever need to make a warranty claim.
What a cooling tune-up should cover
- Cleaning the outdoor condenser coil and clearing debris from around the unit
- Checking and flushing the condensate drain line and pan, and testing any float switch
- Inspecting the indoor evaporator coil and blower
- Testing capacitors, contactors, and electrical connections
- Measuring refrigerant pressures and temperature split to confirm the system is cooling properly
- Checking the thermostat and system controls
What a heating tune-up should cover
- Inspecting burners, igniter, and flame sensor
- Inspecting the heat exchanger and venting, and checking for safe combustion
- Testing safety limits and controls
- Checking blower operation and electrical connections
- For heat pumps, checking defrost operation and backup heat
What you can do yourself
- Change the filter. Check it monthly during heavy use and replace it when it's dirty, often every one to three months. Homes with pets, nearby construction, or heavy spring pollen may need more frequent changes.
- Keep the outdoor unit clear. Leave about two feet of open space around it. Trim shrubs, rake leaves, and avoid blowing grass clippings into the coil.
- Keep supply and return vents open. Closing vents in unused rooms can reduce airflow and strain the system.
- Watch the drain. If you can reach the condensate line's cleanout, a technician can show you how to keep it clear.
- Test CO alarms if you have any gas appliances.
Warning signs between visits
Call for service sooner if you notice new grinding, squealing, or banging noises, a burning smell that lingers beyond the first few minutes of the heating season, water around the indoor unit, a system that turns on and off every few minutes, or a sudden jump in your power bill without a change in weather. Catching these early is usually cheaper than waiting for a full breakdown.
About maintenance plans
Many contractors offer annual plans that include two visits and sometimes priority scheduling or repair discounts. They can be a good value if you'd otherwise forget to schedule service. Read what's included, whether it renews automatically, and how cancellation works. Request a tune-up and we'll connect you with a licensed contractor nearby.
Frequently asked questions
How often should I change my HVAC filter?
Check it monthly during heavy use and replace it when it's dirty, often every one to three months. Homes with pets, allergies, or heavy spring pollen may need more frequent changes.
Is an HVAC maintenance plan worth it?
It can be if you'd otherwise skip annual service. Look at what each visit includes, whether the plan auto-renews, and what discounts or priority scheduling actually apply.
Can I clean my outdoor AC unit myself?
You can keep the area around it clear and gently rinse debris from the fins with a garden hose after turning off power at the disconnect. Leave refrigerant checks and electrical work to a licensed technician.
