Sunny Windows, Shady Trees and Other Non-Electrical Supports to HVAC

The heating and air conditioning system in the average residential home is often the biggest user of energy. Fluctuations in the monthly utility bills are the first clue that homeowners are given to indicate that their HVAC system's efficiency is falling. While the first reaction may be to suspect a mechanical issue or the age of the system, homeowners may also want to first explore another critical possibility within their home environment that may be making their heating and cooling system work less efficiently. 

Humidity levels

A certain amount of humidity is necessary to keep humans and animals comfortable in an enclosed space. Information from the Environmental Protection Agency (EPA) shows that 60 percent is the maximum level of humidity for an indoor space, with lesser amounts — between 30 and 50 percent — preferable. Homeowners who are unsure about their home's humidity level can use a simple, inexpensive tool called a hygrometer to test the air in their home. 

Effects of high humidity

Part of the process involved in cooling the home requires removing excess humidity from the air. When excessive humidity levels exist, the cooling system's condenser components must run longer and more often in an attempt to lower them. Increased run time for the condenser translates into higher energy bills. If the condenser is unable to effectively lower the humidity inside the home, homeowners will notice that they no longer feel as comfortable inside their home. 

Recognizing high humidity

Air that contains too much moisture is uncomfortable to live in and breathe. In the home, high humidity levels that are not quickly corrected can cause a host of issues beyond higher heating and cooling bills including: 

• Mold and mildew formation
• Drip marks on walls and damage to wall coverings and materials
• Clouded window panes and swollen window and door frames
• The development of odors and stains
• Wood rot 

Homes that suddenly develop high humidity issues may be experiencing an undetected plumbing or roof leak, moisture infiltration into their basement or crawlspace, or extreme changes in water-use habits inside the home. Correcting issues that cause humidity levels to raise may be all that is needed to get your HVAC working efficiently once again.

In some cases, adding a dehumidifier unit to an existing HVAC system may be needed to restore proper humidity levels and help increase system efficiency. 

Homeowners who have concerns or questions about their home's humidity levels and how they can help their HVAC system work more efficiently should discuss their concerns with a heating and cooling repair contractor like Soco Air Conditioning at their earliest opportunity.
