Air Conditioner Repair

Armstrong manufactures appliances that homeowners have come to trust. Even a trustworthy appliance requires occasional maintenance or repair, however. If you’re in need of Armstrong appliance repair from experienced professionals, your local Appliance Helper can help.

Maintenance and service must be performed by a qualified installer or service agency. 

At the beginning of each cooling season, the system should be checked as follows: 
1. Clean and inspect condenser coil. Coil may be flushed with a water hose. Be sure the power is off before using water to clean the coil. 
2. Outdoor fan motor is pre-lubricated and sealed. No further lubrication is needed. 
3. Visually inspect connecting lines and coils for evidence of oil leaks. 
4. Check wiring for loose connections. 
5. Check for correct voltage at unit (with unit operating). 

Indoor Coil 
1. Clean coil, if necessary. 
2. Check connecting lines and coils for evidence of oil leaks. 
3. Check condensate pan line and clean, if necessary. 

Indoor Unit

2. Adjust blower speed for cooling. Measure the pressure drop over the coil to determine the correct blower CFM. 
3. Belt drive blowers: Check belt for wear and proper tension.

My home is not getting heat 

Your gas might not be on 
Check the gas valve at your gas meter, the shutoff valve at the furnace and any other shutoff valves. If any are OFF, call the gas company or your local Armstrong Air dealer to have the gas valves turned back on. 

Your system might be turned off or your unit might be unplugged 
Check that all your HVAC equipment is plugged, including the outdoor unit and thermostat. 

A circuit breaker may have been tripped in your home 
Locate your circuit breaker box (or electrical panel). They are typically located on an inside wall at the back of the house. Check the circuit breaker box and make sure breakers are in the ON position. Also check that the disconnect switch (located near the air conditioner or heat pump) is ON. You may need to reset your circuit breaker. 

Incorrect setting on your thermostat or your thermostat may simply be OFF 
Check that your thermostat is ON and set to HEAT. Make sure that the thermostat is set higher than the indoor temperature currently showing on the thermostat. 

Blocked filter 
Check the furnace or air handler filter to see if it is blocked with dust and dirt. If so, change the filter. Remember to change your filter approximately once a month. 

There is no airflow 

Blocked filter 
Check all the filters in your HVAC system components. Follow the recommendations in your user’s manual for cleaning and replacing your filters. 

Dirty coil may have frozen your system 
Check your indoor unit and see if there is evidence of water below the unit. Feel for a cold surface on the indoor coil enclosure. You can turn OFF your thermostat for 1–3 hours to see if it will defrost. Contact a certified repair person if the problem persists. 

Dirty or blocked ductwork 
Check your indoor unit to see (or hear) if the blower is running. Then go to different vents in your house to feel for airflow. If you do not feel any air, contact a certified repair person for duct cleaning services. 

The drain pan is overflowing 

The overflow switch is likely not functioning 
Turn your system OFF and contact a certified repair person. 

My unit runs all the time 

Your thermostat setting might be too high or low 
Adjust your thermostat during extremely hot or cold days so that your heating and cooling system doesn’t have to work so hard. 

My utility bills are higher than normal 

Your system is not reaching its thermostat setting 
If your outdoor temperatures are constantly in the extreme, you may experience higher-than-average utility bills as your system tries to keep up with extremely hot or cold weather conditions. 

Your utility company may have had a recent rate increase 
Check with your local utility company to ask about recent rate increases. Ask them about ways to conserve energy with your existing equipment. It may be time to think about upgrading your equipment for greater energy efficiency. 

Are you using a new appliance that uses a lot of power (hot tub, pool heater, sauna, etc.)? 
You may consider turning the appliance ON for shorter periods of time or completely OFF when not in use.
