Your HVAC system is one of your home’s best allies during the summer season. You’ll be using it all the time to keep yourself cool amidst the scorching summer heat. But what if you notice that your HVAC system suddenly starts blowing warm air even though it’s set it to the coldest setting? In this instance, there might be some problems occurring within your HVAC system.
In today’s post, your AC and home furnace repair specialist, Cooper Brothers, discusses the probable causes for your HVAC system blowing warm air in cooling mode.
Dirty Air Filters
Your AC system’s air filters might be worn out or filled with dirt and debris if your unit is blowing warm or stale air. First, ask yourself when was the last time you cleaned out your AC unit or air filter. When was the last time you changed it? Changing or cleaning your air filter will not only ensure proper airflow and cool air, but it will also contribute to the longevity of your entire HVAC system because it won’t be working harder to blow cold air through a clogged filter.
Thermostat Settings
Check your thermostat settings to make sure they’re actually set to cold. Sometimes, homeowners might forget to change their thermostat settings when adjusting it from season to season. Before the summer season starts, be sure to make a note to adjust your thermostat accordingly to keep yourself cool during the warm summer months. Read up on some of your AC unit’s specific settings to optimize energy savings during the summer. Some AC repair specialists would tell you to set it to “Auto”, as this provides an adequate amount of cooling adjusted to your room’s temperature without using up too much energy.
Worn-Out Compressor
Your compressor is responsible for the cooling in your AC unit. The evaporator coils bring down refrigerant and convert it into high-pressure gas, which then goes into the condenser coils. Once the compressor fails, the entire HVAC unit won’t function properly. Your compressor might fail due to refrigerant issues, electrical failures, overheating or simply because it’s reached the end of its service life.
