Troubleshooting the More Common A/C Problems Homeowners Face

Cooling system troubles are always stressful, but is the problem something you can fix yourself or do you need to call in a pro? Understanding common air conditioner problems can help you decide. Here are a handful of A/C troubleshooting tips to help you out.

The Condenser Isn’t Operating

First, check whether the system is plugged in and receiving power, then try setting the thermostat back five degrees to see if the condenser cycles on. If not, look in the main breaker box for a blown fuse or tripped breaker. Call an HVAC pro if these fixes don’t work.

Insufficient Cool Air

If you notice less cool air arriving at the registers only on extremely hot days, it may not be a cause for concern. An A/C can only bring down the indoor temperature a certain amount in relation to outdoor heat and humidity. If you’re seeing a gradual reduction in cooling output and it’s an ongoing issue, get it checked by an HVAC specialist. Having the evaporator coil cleaned may solve the problem, but if not, the A/C may be too large a capacity for your home.

No Cold Air Output at All

A severe restriction in system airflow can sometimes cause this problem. Check the air filter first and replace it if it’s dirty. You can try gently hosing down the condenser coil and clearing away any tall grass or yard debris from around the outdoor unit. If there’s no improvement, call for service.

Frequent On and Off Cycling

If you have a manual thermostat, adjusting the heat anticipator to lengthen the cooling cycle can often stop inefficient short-cycling. Dirty coils that impede heat transfer are another possible culprit, in which case carefully cleaning the coils may help. If not, it’s wise to get a professional diagnosis.
