Can High Humidity Damage Your AC?


HVAC experts recommend a humidity level below 60% for your home to be comfortable. Have you ever wondered why? High humidity, especially in extreme weather conditions, can affect the cooling performance of your HVAC system. Although the HVAC system is expertly designed to remove moisture from the air, most systems fail to cope when the humidity level spikes. High humidity cancels out the unit’s ability to condense and remove excess water vapor from the air. In short, your air conditioning system will not be able to cool as efficiently as it does during normal days. 

Can a larger, more powerful HVAC solve the humidity problem? 

Many homeowners believe that having a larger, more powerful HVAC unit is the effective solution to counter humid conditions. In reality, that’s not true. It may seem counterintuitive, but a big, powerful HVAC system does a poor job of regulating both temperature and humidity. Their compressor never runs long enough to remove humidity from the air. Moreover, the system will be working longer without providing the desired result – this ultimately results in higher utility costs. 

What you can do?

The most effective and reliable way to manage the moisture in your home is to install a dehumidifier directly into your HVAC system.

The sole purpose is to reduce and maintain the humidity level in the air and make the inside atmosphere comfortable & breathable. The equipment further eliminates musty odors by preventing the growth of mildew. 

Will it work directly with my  HVAC?

Yes, the dehumidifier will work with your new or existing or HVAC system. Once installed, it will automatically pull the excess water from the air before passing through the air ducts to your room. Nevertheless, the dehumidifier’s performance is greatly affected by its size and humidity levels. For the best fitting solution, we recommend you call an HVAC professional. They will measure the area where you want to install a dehumidifier and recommend the best-configured system. With the dehumidifier installed on your HVAC, you will be able to regulate both humidity and temperature inside your home at the same time.

What are the different sizes of dehumidifiers? 

Dehumidifiers are available in many different options, and the one you choose depends on the space and humidity level. The most recommended choices are:

  • 30-Pint Dehumidifier – Ideal for areas up to 1500 square feet and widely chosen for most residential basements. 
  • 40 or 50-Pint Dehumidifier – This dehumidifier size is suitable for areas up to 2000 square feet 
  • 60 or 70-Pint Dehumidifier – Recommended for spaces much larger than 2000 square feet.  

Can you install a dehumidifier on your own?

Installing a dehumidifier requires a well-planned approach. Since it is a heavy and expensive piece of equipment, proper installation is a must to keep it working reliably. Experts with accreditation and training should carry out installations, repairs, and maintenance.

Excessive humidity can affect HVAC system performance, compromise the inside air quality, and even increase the chance of respiratory problems. Installing a dehumidifier into the HVAC system is the best solution for maintaining comfortable and breathable conditions. With a dehumidifier, you will be able to precisely control humidity levels and increase HVAC performance and efficiency throughout the summer.
