HOME ENERGY EFFICIENCY

Get the most out of your HVAC system

Up to half of your home’s energy bills can go to heating and cooling, the EPA says. Make sure you’re saving energy and money by keeping your HVAC system properly maintained. Here’s how to keep your system in tiptop shape. CHANGE YOUR AIR FILTER

Keeping your filters clean is a simple task that can save you big bucks. It’s made even easier if your thermostat is able to set reminders. If not, set a reminder on your phone or calendar to change out the filter every three months. Dirty filters slow air flow, making the system work harder to keep you comfortable. It can lead to dirt and dust clogging your ducts, damaging your system. GET A TUNE UP

Have an HVAC professional come check out your system annually. A typical check-up includes tightening electrical connections, inspecting the condensation drain, lubricating moving parts, cleaning evaporator and condenser coils, checking coolant levels, checking gas connections, and adjusting blower components. SEAL UP YOUR DUCTS

As much as 30 percent of the cool or warm air moved around your home is lost by a leaky duct. Fix the problem by venturing into your attic or crawl spaces and tape up leaky ducts with foil tape (not duct tape, surprisingly). Ask your local home improvement center for the right product.

Start by looking for obvious holes and tears. Once they're sealed, move on to the connections at the vents and registers, making sure each spot is sealed tightly. If you have flexible ductwork, check to make sure it moves in gentle curves and hasn’t been squashed.

Insulating your ducts can also help increase efficiency and reduce cost. ASK THE PROS

If it has been a few years or you feel that it is best left to the professionals, contact your local utility company. It may perform an energy audit for you or have a list of contractors who can do this for a reasonable price.
