air conditioner’s warning signs

The 100-plus degree days have arrived, marking the beginning of air conditioning season. Air conditioners can fail at any time.

“Some of the warning signs are fairly obvious, while others are subtler,” explained Bryce Heffelfinger, owner of A/C Expertek in Goodyear. “Knowing the warning signs will allow you to get professional service before the problems get out of control.”

A typical air conditioner will last about 10 years. If an air conditioner is running but the house is not as cool, it can be a sign of:

• low Freon levels

• compressor failure

• a clogged air filter

• a clogged return duct

Heffelfinger advises homeowners to inspect their air conditioners – inside and outside the house. Look for any oil spray or splatters on the air conditioner’s components, which would indicate a major seal gasket has blown and caused the unit’s Freon to leak. A Freon leak should be fixed immediately; if the unit’s Freon goes dry, the compressor will sustain major damage.

“The only noise you should hear is the steady quiet hum of the air conditioner working smoothly,” Heffelfinger continued. “If you’re hearing rattles, bangs, or other noises, it’s not functioning properly. A technician can identify these noises and their root problems.”

Most repairs on air conditioners are quite simple, but homeowners frequently avoid a check-up as they fear a large bill, he said. If the AC unit is new, the repair may be covered under a manufacturer’s warranty. Even if it is not new, it’s best to fix a small problem quickly rather than delay and let it grow into a larger problem, Heffelfinger added.

“If your unit is older than 10 years, our technicians can give it a thorough check during an annual check-up or as part of a maintenance plan,” Heffelfinger explained. “We can also give you an indication of the unit’s remaining life.”
