According to the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE), your heating and cooling system uses more energy than any other system in your home. It’s estimated that heating and cooling accounts for nearly 40 percent of a typical utility bill.

You can save money by regularly maintaining and upgrading your heating and cooling system along with appropriate insulation, air sealing, and thermostat settings.  By doing this, the EERE estimates you can save on your heating and cooling bill, and reduce environmental emissions from 20% to 50%.

Here are a few tips to save on your heating and cooling bill:

  • Use a programmable thermostat and set it at a comfortable temperature.
  • Clean or replace your furnace filters once a month.
  • Clean your warm-air registers, baseboard heaters, and radiators as needed.
  • Bleed trapped air from hot-water radiators once or twice a season.
  • Place heat-resistant radiator reflectors between exterior walls and the radiators.
  • Turn off kitchen, bath, and other exhaust fans within 20 minutes after you are done cooking or bathing.
  • During the cooler months, keep the drapes on your south-facing windows open during the day to allow the sunlight to enter your home and closed at night to reduce the chill from cold windows.
  • During the warmer months, keep the window coverings closed during the day to prevent solar gain.
  • Select energy-efficient products when buying new heating and cooling equipment.

By following these tips, you should notice a reduction in your heating and cooling bill! For more information, you can speak to one of our team members or you can contact us online!

No matter how long the winter, spring is sure to follow.  ~Proverb

Thank goodness for that! With Spring comes blue skies, warmer days, longer nights and…..spring cleaning?

That’s right…spring cleaning. What do we have to do with spring cleaning? There’s never a better time to get your AC in shape for the Spring and Summer months! We have complied a list of things you can do to prep your HVAC for the change in seasons.

  1. First and easiest thing to do? Change your filters! This isn’t just for Spring but now is a good time to do it!
  2. Pop your head into your attic to see if your ducts are sealed properly. How would you know? If you have the air on and it’s cold in your attic, you have a leak.
  3. Take a look at your condenser unit outside and see if it looks clean and free of debris that might stop the blades from running. During the winter leaves or dirt can get in there from the weather and they need to be removed.
  4. Make sure your exterior pipes are still properly insulated and protected from the weather. They can take a beating over the Winter months.

The lights in my home dim when my cooling unit turns on. Does this mean there is a problem with my unit or my breaker panel?

Air conditioners, refrigerators, freezers, furnaces and other devices that have large motors require large amounts of power when the motor first starts. Once the motor is spinning, the energy requirement drops down.

This instantaneous need for motor shaft speed can cause a momentary dimming of your lights. AC units come equipped with start-up capacitors. These give the motor an electric boost when it first starts up. But over time, these capacitors can get weak and become ineffective. Eventually the power draw can cause circuit breakers protecting the wiring to the units to trip.

Your air conditioning system may also be overcharged with refrigerant. Overcharging puts stress on the compressor, and in turn the motor, when it tries to get the compressor engine moving.

Excessive dimming can also be caused by a loose neutral wire in the breaker box. Your AC serviceman can check for overcharging of your AC unit, properly working start-up capacitors and loose neutral wire connections.
