Alaskan Air Conditioning lists the most commonly reported air conditioning problems so that you may be more aware of what is major or what may be minor issues with your HVAC system. Major issues should never be ignored. Some of the other issues, however, you may be able to fix it yourself.

Here are Common Major Issues That Need Expert HVAC Attention Immediately:

Iced up system: on indoor unit, outdoor unit or any connections. This indicates a major issue with your coil.

System never quite reaches the temperature it is set for: this could indicate a lot of issues: needs refrigerant, needs maintenance or cleaning, bad condenser, etc. Very common, too, is the thermostat is no longer operating properly and needs replacing.

Blowing hot air in the cooling mode: this is a major system malfunction. It may be time to replace the refrigerated air system if it is over 10 years old and consistently malfunctioning.

High electric bills in the summer: this probably means your system is running constantly and never shutting off. It is definitely time to replace it with a higher efficiency model. Your old system is nearing the end of its life and actually costing you money on high utility bills.

Not cooling: If bad weather, including  lightening and storms, have been occurring in your area like Phoenix and Tucson’s most recent monsoons, you may have a tripped system. You can try to reset it if you are familiar with the controls or breakers, but if not, give us a call. We can help and diagnose if there may be bigger problems.

Loud noises: Turn the system off and call immediately. This is a symptom of a major issue. Scary noises to look for are scraping, thumbing and banging. Sometimes you will hear humming, rattling or vibrations, but those sounds are less concerning and are cured with regular maintenance. However, if you are unsure, call for service immediately.

Minor Issues:

Thermostat keeps shutting off or has red light lit: this usually is a simple change…most likely it’s time to replace the batteries.

Dust and odors: this can mean it’s time to simply change your air filter. If the dust and odors persist and you have not had preventive maintenance done on your system, you can minimize it by calling for service.

Indoor fan won’t shut off: make sure you have your system on “auto” and not “on.” Fans are best to operate on the auto setting and call for air conditioning as needed. If set to on, the fan runs all of the time. If that doesn’t work, give Alaskan Air Conditioning a call to properly diagnose.

Not enough airflow in some rooms: with a new system installation from Alaskan Air Conditioning, our customers get “balancing.” That where we may install movable blade style registers with dampers to provide air to the rooms that call for it most. Or, we may suggest you Aeroseal your air ducts. Air ducts leak and if you have major duct leakage, you are losing air to unconditioned spaces. Aerosealing the air ducts seals the holes and creates better airflow throughout the home.

These are just some of the problems you may encounter with a air conditioning system. If you are experiencing a problem from our list that is major and needs immediate attention, call Alaskan Air Conditioning to schedule a repair or replacement quote.
