Reasons for AC Repair in Howard County, MD

by | Jul 16, 2018 | Heating and Air Conditioning

Being sticky and hot during the summer is quite the hassle, and when the AC runs constantly, it becomes annoying and expensive. If the unit always seems to be on, there are a few troubleshooting tips to help find the root of the problem. Below are a few things to look for and information on how to prevent these issues from occurring.

Improper Installation and Unit Size

It’s crucial to start the discussion with a fact: an energy-efficient, properly sized central AC unit will run almost constantly during summer to maintain the desired temperature. If the unit’s too small, it will struggle to cool the home and will fail prematurely. However, if a unit is too large, it won’t remove moisture from the indoor air and will cycle rapidly, using more power than it should. Solve the problem by asking the technician to perform a cooling load calculation before AC installation.

Dirty Air Filters

If it’s been a while since the air filter has been changed, it’s likely so dirty that it’s inhibiting air flow. This reduces the amount of cold air the unit produces, which makes it run more throughout the day. Surprisingly, most HVAC failures are due to clogged, dirty filters, but cleaning the debris or changing the filter once a month will ensure free airflow and keep the unit working as it should.

Thermostat Failure

If the system never seems to shut off, the thermostat may be to blame. While it may be due to the home not reaching the desired temperature, the thermostat may not register the conditions inside the home. If basic troubleshooting steps don’t resolve the problem, call a pro for Ac Repair in Howard County MD.

Poor Insulation

Insufficient insulation or poor sealing is another reason a unit may run inefficiently and constantly. If the home isn’t sealed tight when the system is being used, all that cold air may flow right out through the walls, windows, and roof. During maintenance calls, a technician may look for potential problems in the home’s insulation.


Any of these issues may cause an air conditioner to run more than necessary, which costs money. In such a situation, it’s best to contact a professional for Ac Repair in Howard County MD. Call Maryland Heating & Air today to schedule maintenance, installation, or repairs.
