HOW IT WORKS
On the cooling side, the unit draws warm interior air into the system through a series of air return ducts. The air is then moved over a series of refrigerated coils. As the air moves over the coils, the heat in the air is transferred to the refrigerant in the coils. A fan or blower sends the cooled air back to the interior of the building through a series of ducts. The heating side typically relies on a furnace or heat pump to provide warm air through the same ventilation system. To simplify, the system can make hot air cold and cold air hot.
WHY SHOULD YOU CARE
The HVAC system uses more energy and drains more energy dollars than any other system in your home. On average, 44 percent of your utility bill goes toward heating and cooling. For the past 30 years, manufacturers of HVAC equipment have made the system more efficient to help battle rising energy costs. The United States Environmental Protection Agency has also imposed tighter restrictions in recent years in an effort to help save the planet. You can save yourself some money and increase your comfort by properly maintaining and upgrading your HVAC equipment.
PICKING THE RIGHT ONE
The size of your HVAC unit varies based on the size of the space you’re trying to heat and cool. A unit sized too small will constantly run and may never reach the desired temperature. A unit that’s too large will start and stop frequently. The short-cycle causes unnecessary wear and tear on the unit and shortens its lifespan. Figure out the square footage of space you need to heat and cool by measuring the room’s length and width. Multiply the numbers to get square footage, then consult with a professional.
Almost all HVAC brands offer manufacturer rebates. To save even more, request written estimates from at least three contractors. Let them know you’re getting multiple bids so they will quote you their best price. Like the cost of a house or car, price is negotiable.
Timing is also important. HVAC contractors are busiest when the weather is hottest. You’ll probably find a better deal in the off-season when business is slow. Once you settle on a contractor, ask about government tax credits and utility company rebates. The federal government is offering an energy efficiency tax credit and some utility companies are rewarding the purchase of energy-efficient products with rebates. There’s no word on how long the credit and rebates will last, so act soon.
WHEN TO REPLACE YOUR UNIT
The salt in our air isn’t kind to HVAC units. Has yours been around for a decade or longer? If so, you may want to consider replacing it. Most warranties last from five to 10 years. After that, the cost of repairs could soon be greater than the unit’s value.
Using your car as an example, is it really worth spending $4,000 on a transmission when the value of the 10-year-old vehicle is $5,000?
Fact is, older systems are not as efficient. You could save 50 percent or more in utility costs with a system upgrade. Over time, coils get dusty, the refrigerant level may fall and drain lines may get plugged. Maximize your unit’s durability with an occasional tune-up.
Doing so will make our upcoming Dog Months a bit more manageable. It also means you’ll have less to complain about when that payback phone call from your friend inevitably comes.
