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:  Why should homeowners schedule annual maintenance inspection on their heating and cooling systems?

A:  One of the reasons to have annual maintenance inspections for your heating and cooling system is to ensure that it is performing at maximum efficiency, which directly affects your monthly utility bills. You also want to make sure your equipment is functioning correctly and catch any problems before they become major expenses. Regular maintenance will often pay for itself in lower repair costs. Lastly, you want to make sure that your heating and cooling system is functioning properly to avoid any safety problems that could endanger your home and family, i.e. loose electrical connections or holes in your system’s heat exchanger can cause a carbon monoxide leak.  Contact A.J.

Q:  What causes my faucet to drip?

A:  Most faucets work with a rubber or composition washer that closes onto a metal washer seat.  Over time, the washer will harden and crack or simply gets worn down.  This causes the faucet to leak.  You can close the faucet tighter to stop the drip, but this will only be a temporary fix.  In fact, you’re just increasing the internal damage to the washer and faucet and the problem is only going to get worse.  Usually when the faucet drips, the problem has a relatively simple solution:  the washers or other internal mechanisms need to be rebuilt or replaced.  You can do this yourself or contact a professional plumber who can fix this easily and inexpensively.

Q:  Why is it important to change the filter on my furnace?

A:  During peak season usage (cold winter months), by simply changing your furnace filter you can make the difference in how well your system performs and how much energy it uses.  A dirty filter forces your furnace to work harder, eating up energy and increasing your energy costs.  Over time, this can even damage your system, decreasing its lifespan.  Also, filters that are rarely changed can aggravate allergy problems and lower the quality of your indoor air.
