Tip of the Month

Closing HVAC vents in unused spaces/rooms in your home has been a common practice, but it doesn’t actually save money, it could cost you.  This practice dates back to a much earlier time in history, when homes were heated from a central location, like a fireplace.  Back then it worked.  Today, however, homes are equipped with central heating and air conditioning and closing off parts of your home by shutting vents can actually increase your energy costs, not reduce them.

First, HVAC systems in modern homes are designed to heat or cool the entire home and are sized according to this need.  By shutting off a part of the air flow, you increase the air pressure within the system, which increases the amount of leakage from the ductwork.

Second, too many closed vents can actually cause your HVAC system to malfunction.  Your system relies on a certain amount of air flow to maintain a certain temperature.  Reducing air flow in your furnace can cause furnace burners to shut down, a protective function that prevents overheating and possible damage to your system.  Once this occurs, however, the system can no longer heat.

And lastly, most internal doors are not weather stripped, so that there is no threshold to prevent air exchange from the rest of the house.  This allows unconditioned air to be drawn into the occupied air and causes your system to work harder to compensate for the vents that were installed to handle the closed off rooms.

Q&A’s – HVAC & Plumbing

Q: What’s the best way to get my air conditioning running in the spring?

  1. Remove the air filter on the furnace and clean it out.
  2. If you have a humidistat, turn it from 35% to 0%.
  3. 24 hours before starting your air conditioning, turn the disconnect back on.
  4. Wash the condenser unit (that’s the unit outside your house). Set your hose nozzle for a fine spray of water and spray from the top down.
  5. Turn on your air conditioning and enjoy the cool comfort inside.

If you haven’t already, be sure to schedule a tune-up for your air conditioning before the heat of the season is in full swing.  Annual maintenance improves efficiency and increases safety, comfort and reliability. 

Q: What are some things I can do to take care of my faucets and sinks?

A:Even small drips can waste thousands of gallons of water, as much as 150 gallons a day. Be sure to check under sinks for moisture or small leaks. And always repair leaky faucets right away to avoid paying for wasted water, and also to avoid water damage to your fixtures and pipes and surrounding areas. Remove and clean your faucet aerators annually to ensure an even flow of water. Make sure overflow holes on tubs and vanities are clear and open to prevent water damage to floors and ceilings.
