Heating and Air Conditioning questions, answered by experts

To make the most out of your AC, consider implementing the following best practices:

Choose the right size AC for your home to ensure your unit runs as efficiently as possible.
Choose a window with shade, as direct sunlight can cause your AC unit to overheat.
Clean or replace the filter at least every two months.
Inspect the AC’s fan and straighten it if necessary.
Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues.
Turn off (or adjust the temperature) when you leave the house.

There are several tell-tale signs that your AC coils need cleaning, including:

You’re getting higher electricity bills.
Your home doesn’t feel as cool as it usually does.
Your AC unit is running longer than usual to cool your home.
Your home is more humid than usual.
The coil is covered in frost while running.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.
