  • How often do I need to change my air filter?

    A good general guideline is to change your air filter once a month. However, factors like location, dust, pet dander, and other airborne particles may require you to replace it more or less frequently. Check your filter regularly, and if it looks dirty, it’s time for a change.

  • If I replace my outdoor unit, do I also need to replace my indoor unit?

    Typically, yes. Replacing both the indoor and outdoor units at the same time is recommended for several reasons. Outdoor units, such as air conditioners and heat pumps, are designed to work with matched indoor units, so pairing them ensures optimal efficiency and performance.


    Also, if both units were bought at the same time, the indoor unit may be nearing the end of its lifespan as well. Replacing them together can help you avoid higher energy costs and secure a warranty covering both units for easier repairs in the future.

  • Should I cover my unit in the fall and winter?

    While covering your unit can keep debris from accumulating, it can cause issues if you accidentally run the unit with the cover on. If you’re going on an extended trip and plan to turn off the unit, covering it is fine—just remember to disconnect the power before you leave.

  • How often should I have my unit serviced?

    Regular maintenance is essential to keep heating and cooling units operating effectively. HVAC professionals recommend scheduling a service inspection once a year. During this visit, technicians will check your system, lubricate moving parts, and repair or replace any faulty components.

  • How do I find out if my unit is under warranty?

    You can check the warranty status by looking at the label on the outer surface of your equipment to find the manufacture date. If your unit is under five years old, there’s a good chance it’s still under warranty. For specific details, reach out to the manufacturer.

  • What can I do to lower my energy bills?

    • Install a programmable thermostat to reduce energy use when you’re not home
    • Replace incandescent light bulbs with energy-efficient options like CFLs or LEDs
    • Use ceiling fans as an alternative to air conditioning when possible
    • Unplug appliances not in use, as they can still draw power when turned off
    • Seal windows and doors to prevent air leaks, helping your HVAC system run more efficiently
  • What should I consider when adjusting the thermostat?

    • Programmable Thermostats: Use these to preset temperatures for different times of day and night to save energy.
    • Consider Your Lifestyle: Adjust your thermostat to fit your daily schedule and comfort preferences.
    • Weather: Take outdoor temperature and humidity into account when setting your thermostat.
    • Insulation: Ensure your home is well-insulated to maintain a stable temperature and reduce energy use.
