  • Why does my furnace smell hot when I first run it in the winter?

    While your heating system sits idle throughout the summer, dust can build up on the heat strips. The first time you run it in the winter, that dust burns off harmlessly.

  • How often should I change my HVAC filter?

    For optimal efficiency, you should change a standard 1"-thick furnace or air conditioner filter every month. We recommend changing it when you pay your electric bill.


    Some filters claim to last longer than a month, but changing them often is still a good idea.

  • How often should I have my HVAC system serviced?

    Having your heating and air conditioning system serviced twice a year keeps it operating at peak efficiency. When you have us inspect and maintain it at the beginning of the upcoming winter or summer, it's ready for the stress.

  • Why is my electric bill higher in the winter?

    If you have a heat pump system and the outside temperature is below 32°, it uses electric heat strips to back up the pump. These consume three times as much electricity.

  • Does mowing my lawn hurt my air conditioner?

    It's possible that debris from mowing can obstruct intakes that your air conditioner needs to operate efficiently. When leaves, lawn clippings, and other debris obstructs the airflow, the equipment has to work harder.


    We recommend sweeping away and washing off anything that might be blocking the vents or the coil on your outdoor AC unit.

  • What can I do if my heating or AC locks up?

    It's possible that a minor obstruction can cause your HVAC system to shut down or freeze. Turn the thermostat to the Off position and the fan to the On position, and check the filter to see if it needs to be changed. You should also check for anything near the return that might obstruct the airflow.


    If that doesn't work and the system looks clear, please call Gregg's Heating & Air LLC for prompt service. Emergency services are available!

  • Can I cool down my building more quickly by setting the thermostat to 60°?

    No. Your air conditioner only operates at one speed. Setting your thermostat for a lower temperature will not make it work any faster.


    This is also true for heating systems. Setting them to 100° would not heat up the building any more quickly. 


    The energy-efficient way to make your home or business comfortable is to set the thermostat at the desired temperature and let the equipment work as it was designed to work.

Tips to Help HVAC Equipment Operate More Efficiently

There are several things you can do to help your residential or commercial heating, air conditioning, or HVAC unit operate more efficiently.


  • Maintain free airflow — All heating and cooling units need to have a good airflow. If you have an outside air conditioner (a condenser), do not build a roof less than five feet above it. Do not install any landscaping (like flowers, shrubs, or retaining walls) within three feet of it.
  • Balance your temperature to reduce costs — In the winter, leaving your thermostat set at one temperature helps you to save on your electric bills. In the summer, you can cut costs by setting your AC temperature two degrees higher when you're out of the house during the day.
  • Have us perform regular maintenance — When you have Gregg's Heating & Air service your HVAC system every year, we can spot minor issues before they turn into large problems and costly repairs.
  • Change your filters on schedule — Dirty filters raise your utility bills! If the unit has to work harder to pull new air through a clogged filter, it operates less efficiently and costs more to run. Change your filters monthly, and be sure to keep the return air grille clean, as well. Do not obstruct return air grilles with plants or furniture.
