Does your HVAC system suddenly feel like it is not producing enough cold air during the summer? If so, it's a problem you'll want to get to the bottom of very quickly. Here are some reasons that can be causing your home to feel warmer than usual.
Installing New Room Sensors
One new innovation with smart thermostats is that it allows you to put temperature sensors throughout your home. Normally, you are limited to having the HVAC system read the temperature at the location of the thermostat, but this is no longer the case. Unfortunately, the locations of the room sensors could be causing the issue if the thermostat is now reading an inaccurate temperature. The sensors are relaying to the HVAC system to not turn the air conditioner on and cool down your home because it thinks that it is not necessary. Thankfully, this is a problem that is easy to fix by adjusting the position of the room sensors.
Put the sensors on an interior wall that is going to accurately reflect the temperature of the room. Keep them away from the direct blast of a nearby air vent, which can make a room appear to have cooled down quickly.
Adding An Addition
If you recently added an addition to your home, you likely tried to use the existing HVAC system to cool it down. The problem is that you just added a bunch of square footage to your home, and your HVAC system may not be able to handle the additional cooling needs. You may end up with rooms that are not getting enough cold air because of modifications you made to the duct work, which are causing rooms to feel hotter than normal.
You may be better off closing off the ductwork to the new rooms and installing a separate air conditioning system for the addition. You can also upgrade your air conditioner to a more powerful unit that can cool off the entire home.
Having A Refrigerant Leak
It's also possible that your air conditioner has caused the temperature of the air to get warmer due to a leak in the refrigerant line. Refrigerant is what carries the heat out of your home to cool down the air, and without enough refrigerant, the system can be lacking in terms of the temperature of the air. Have an air conditioner service come inspect the system for a refrigerant leak and perform the necessary repairs.
