Armstrong Air Conditioner Troubleshooting
If you're looking for help fixing your Armstrong Air Conditioner, look no further! Our comprehensive Armstrong Air Conditioner Troubleshooting guide will explain common issues, provide tips, and show you how to read your model's error codes.
My home is not getting cool air
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 COOL.
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
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.

Armstrong Air Conditioner difficulty
I bought this new unit to replace one I had for 20 years. The main reason I replaced it was because of efficiency issues plus difficulty in finding parts. This Armstrong I bought works well though. I haven’t had any trouble with it for the ten months I’ve had it. Good ac with great functionality.
Before I posted this I looked through the reviews and found that there are plenty of people who have had a bad experience with Armstrong. I’m glad I haven’t had to deal with any malfunctions. It’s been a year and a half now and so far the AC keeps the house cool and has great energy efficiency.
2 years and nothing is the problem. If only every other manufacturer made such reliable equipment. The Armstrong AC I bought 2 years ago hasn’t had any problems apart from a Freon leak that was fixed under the warranty. I’m looking forward to many more years with this unit.
Moving to a new place is expensive, especially if you have lots of repairs to take care of. For me, the worst thing is moving in and having to bear with the scorching heat just because the ac doesn’t work. When we moved in here the ac was one of the first things I made sure were functioning. I replaced the old Carrier I found with an Armstrong unit. So far I can’t complain about its functionality. The unit cools the house so well and isn’t one bit noisy.
Armstrong is a quality brand. I say this because my neighbor has had a Trane and a Rheem in a span of 6 years. I think he got ripped off twice by two companies. My ac has been in service for the last two years and I haven’t spent a dime to fix it. It’s a good deal but you appreciate it more when all you read online is about bad experiences and disgruntled customers. Hurray for Armstrong, I strongly suggest you check them out before your AC or replace an old one.
