5 Common HVAC Mistakes Homeowners Make

Many homeowners have certain bad habits when it comes to their heating, ventilation and air conditioning systems. It may seem like it doesn’t really affect your home, but in reality these bad habits can lead to a lot of problems such as issues with comfort, an increase in utility bills, and it shortens your system’s lifespan.

Here are five common mistakes homeowners make and how to avoid them, hopefully saving you some money and helping your HVAC system out:

Extreme Thermostat Temperatures

Homeowners commonly believe that it saves money to set the temperature to extreme levels when they are out of the house. Completely shut the system down and then just let it adjust when you get home right? Wrong. This practice means that your HVAC system will be operating ceaselessly for around 3 to 4 hours as you wait for the temperature to be brought back to what is normally desired.

It is better to set the thermostat to no more than 3 degrees higher than the normal temperature you desire when you leave the house to avoid uncomfortable temperatures and excessive work for your HVAC system.

Closed or Blocked Vents

Another bad habit some homeowners practice is closing vents in rooms that are rarely used with the belief that it will save energy. This is impractical because closing vents will create negative pressure which will send the air in places you do not want it to go.

Closing vents will also make your HVAC system work harder to maintain the set temperature, therefore damaging it as well as increasing its energy consumption. There are better ways to seal off a room or adjust your system than simply blocking certain vents.

Blocked Condenser

The purpose of an outdoor condenser is to release the heat that the refrigerant absorbed from inside the house. If it is covered by plants, weeds, debris, and the like, the airflow will be hindered and it will not be able to do its job properly.

To maintain the efficiency of your HVAC unit, clear anything around the condenser such as debris and plants on a regular basis. It is also wise to have a professional, like the experts from Ardmore Fresh Air, to clean the condenser coils at least once a year.

Dirty Air Filters

Dirty air filters will make your HVAC unit less efficient because dirt blocks airflow, so therefore it will work harder to draw air. This runs the risk of damaging the HVAC system, increasing your energy bills as well as having a negative effect on air quality.

Replace your unit’s filters regularly, ideally around 30 to 60 days, to make sure your HVAC unit works as efficiently as it should.

Irregular Maintenance

Similar to your car, HVAC systems require regular maintenance to keep the unit in perfect working condition.

It is a good practice to schedule maintenance sessions with Ardmore Fresh Air technicians ahead of time to minimize the chances of emergencies. And continuing service and maintenance on time greatly increases the chance that our professionals will discover needed repairs before parts of your units break down completely.
