Spring is the best time to get your air conditioner ready for the heat and humidity we see across Eden and the surrounding NC and VA communities. A few simple maintenance steps now can help your system cool better, run more efficiently, and avoid surprise breakdowns when temperatures climb.
At Dyer’s Plumbing & Air, we recommend a two-part approach every year:
- A quick homeowner checklist you can do in an hour or less, and
- A professional tune-up before peak summer demand.
If you’d like to get on the schedule, call (336) 863-1963 or request service online.
Why spring AC maintenance matters
During the off-season, outdoor units collect leaves and pollen, filters load up with dust, and drain lines can start to clog. When you flip the thermostat to cool, all that buildup can lead to weak airflow, uneven temperatures, higher energy bills, and water leaks.
Regular maintenance also helps catch small problems early, before they turn into bigger repairs during the hottest week of the year. ENERGY STAR specifically recommends pre-season checkups (cooling in spring, heating in fall) to avoid the seasonal rush.
Before you start: 2 safety basics
- Turn off power to the system before you work near the outdoor unit (thermostat off, then breaker/disconnect as needed).
- Do not open the refrigerant system. Refrigerant handling is regulated and should be done by a certified technician.
DIY spring AC maintenance checklist
1) Replace or clean your air filter
A clogged filter restricts airflow, makes your system work harder, and can contribute to comfort and performance issues.
- Check the filter monthly during the cooling season.
- If you aren’t sure, the U.S. Department of Energy suggests cleaning or replacing filters every month or two during cooling season (more often if you have pets or dusty conditions).
Pro tip: Make sure the filter fits snugly so air doesn’t bypass around it.
2) Clear debris around the outdoor unit
Your condenser needs airflow to dump heat outside.
- Remove leaves, sticks, and weeds
- Trim shrubs back to give the unit breathing room
- Make sure the top is clear (no covers, toys, or patio furniture nearby)
3) Gently rinse the outdoor coil (skip the pressure washer)
Dirty coils reduce cooling ability and can increase energy costs and wear.
- With power off, use a garden hose on a gentle setting
- Spray from the outside in (lightly) to rinse pollen and grime
- Avoid bending fins
If the coil is heavily matted with dirt or cottonwood, it’s time for a professional cleaning.
4) Check the condensate drain line and drain pan
A clogged drain can cause water damage and humidity problems.
Look for:
- Water around the indoor unit
- Musty odors
- Visible algae buildup
If you see water or repeated clogs, schedule service. We can clear the line properly and confirm the drain is pitched correctly.
5) Test the thermostat and cooling cycle
Set the thermostat to Cool and lower it a few degrees.
Listen and watch for:
- Outdoor unit starts smoothly
- Indoor airflow feels steady
- Supply air becomes cooler after a few minutes
If your system short-cycles (turns on and off frequently) or blows warm air, stop running it and call for help.
6) Walk your home and check airflow
- Make sure supply vents and return grills are not blocked by rugs, furniture, or curtains
- Replace crushed or disconnected flexible duct sections you can safely access
- Note any rooms that are always warmer than others (this helps us diagnose airflow or duct issues)
7) Do a quick comfort sweep before summer
These small steps reduce strain on the AC:
- Seal obvious air leaks around doors and windows
- Close blinds during the hottest part of the day
- Use ceiling fans to improve comfort so you can set the thermostat a bit higher
What a professional spring AC tune-up should include
A real tune-up is more than a quick look. Our maintenance checklist includes tasks like checking thermostat settings, tightening electrical connections, lubricating moving parts, inspecting the condensate drain, and cleaning/inspecting coils.
Professional maintenance can also include checking refrigerant charge and leaks, sealing duct leaks, measuring airflow, and verifying electrical control sequences.

Spring warning signs to watch our for
If you notice any of these, it’s best to schedule service before the first heat wave:
- Warm air from vents or weak airflow
- Ice on the refrigerant line or indoor coil
- Water around the indoor unit
- Burning smells, buzzing, or frequent tripped breakers
- The system runs nonstop but never catches up

FAQ: Spring AC maintenance
How often should I schedule AC maintenance?
For most homes, plan on annual pre-season maintenance, ideally in the spring before summer demand ramps up.
How often should I change my AC filter?
Many homes do well with checking monthly and changing as needed. The U.S. Department of Energy suggests every month or two during cooling season if you’re unsure, and more often with pets or dusty conditions.
Can I clean my AC coils myself?
You can gently rinse the outdoor coil, but deeper cleaning is best left to a technician. Dirty coils reduce cooling performance and can raise energy costs.
Why is my AC leaking water?
Often it’s a clogged condensate drain or a dirty coil causing poor airflow and freezing. Either way, it’s worth a professional inspection to prevent water damage.
Should I top off refrigerant if cooling is weak?
No. Low refrigerant usually indicates a leak, and refrigerant handling should be done by certified technicians following EPA requirements.
