"After being ghosted by several AC companies we were thrilled to have Behold answer their phones, make and keep appointments, and show up for the install. Our 1970s house is blazing hot upstairs in the summer, and after considering several options we settled on a mini split. It was installed today and our bedroom is delightfully cool. Both guys on the job were professional and courteous. They kept us appraised of what they were doing and showed us how everything worked at the end of the day. They have also promised to file all applicable rebates."

"It was very easy to work with D&D Air Duct Pros. They were very responsive and made scheduling easy. They showed up on time, were very friendly, and did a great job. They provided before and after pics of our ducts and went above and beyond to make sure they were as clean as possible! I would definitely recommend this pro."

Air Conditioning FAQs, answered by experts

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

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.

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

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.

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.
