What you can do yourself
- Clean what you can
Clean or replace any filters inside your system’s indoor unit. Also, clear away any dirt, leaves, and debris from your system’s outdoor unit.
Pro tip: Keep plants, weeds, shrubs, and other vegetation at least 18 inches away from your outdoor unit to avoid debris buildup.
- Watch out for leaks
Check for leaks or holes in your system’s ductwork, evaporator coil, or cabinet (the outside “shell” of your unit that holds all the parts inside together).
- Keep your ears open
Listen closely for any strange noises when your system starts. If you hear any, call a technician to inspect the problem more closely.
- Perform a smell test
Take note of any suspicious or unusual odors when your system starts. If you smell anything strange, call a technician to identify the issue.
- Keep your vents clear
Make sure you move any furniture, drapes, rugs, etc. that could be blocking your supply and return vents.
When to call a technician
- Your energy bills keep rising
If your utility bills increase but your overall usage remains the same, one or more components of your system may not be working as they should.
- Your comfort isn’t consistent
If your air conditioner, furnace or other HVAC system can’t maintain consistent temperatures, a technician is the best person to investigate the issue.
- Your unit’s fins are damaged
Bent or damaged fins on your air conditioner or heat pump’s outdoor unit can trap heat inside your unit, causing performance and temperature issues.
- Your unit takes on a lot of water
Excessive water, such as from a flood, can seriously damage your unit’s electrical systems. If you suspect that your unit’s mechanical equipment might have water damage, do not attempt to resolve the issue yourself. Call a technician. Electrical problems are potentially life-threatening and should only be handled by a professional.
- You smell electrical burning
Turn off your unit immediately and call a technician. A burning smell could mean your unit is experiencing a malfunction or electrical issue requiring professional attention.
