How often should I replace my air filter?
The air filter on your HVAC system needs replacement every 1 to 3 months. Simple 1" panel filters need changes more frequently, while 4" pleated filters can last for 3–6 months.
Do you offer financing on equipment?
Yes, we offer financing through GreenSky. Call for details at (763) 445-4725.
What does MERV mean?
MERV stands for Minimum Efficiency Reporting Value. It’s the standard measurement used for the effectiveness of air filters. The higher the MERV rating, the smaller the particles the filter will trap. Most residential air filtration systems will use filters with MERV of 8 to 12. A filter with a MERV rating that is too high will restrict airflow through the ventilation system.
How can I improve the air quality of my home?
- Allow for fresh outdoor air circulation when the weather permits.
- Change the HVAC filter every 1–3 months.
- Clean and dust the house regularly.
- Install a whole-house dehumidifier or humidifier.
- Have whole-house air filters and air purifiers installed.
- Invest in an energy recovery ventilator or heat recovery ventilator.
- Arrange for professional air duct cleaning every few years.
What is a zone control system?
Zone controls divide a home's HVAC system into separate areas so that the whole house doesn’t need to be heated or cooled simultaneously. A central thermostat and local room thermostats can restrict heating and cooling to specific zones, ensuring that the HVAC system doesn't expend extra energy on unoccupied areas of the house.
What does a heat pump do?
A heat pump is a refrigerant-based comfort system that works similarly to an air conditioner. However, it can switch the direction in which it operates, so it can work either as a cooling system (moving heat out of the house) or a heating system (moving heat into the house).
What is a ductless system?
A ductless system is a type of heat pump. Unlike standard central heat pumps, ductless systems do not use a single indoor unit connected to a network of ducts. Instead, the outdoor unit connects to 1–4 smaller indoor units mounted up on the exterior walls of rooms around the house. These units contain blower fans and refrigerant coils and send conditioned air directly into the rooms. Each wall-mounted unit can be operated independently of the others.
How can I heat my home more efficiently?
- Always have your heating system professionally maintained.
- Change the furnace air filter every 1 to 3 months, so it won’t clog.
- Place weatherstripping around doors and caulk windows.
- Make sure no room vents are closed or obstructed.
- Rotate ceiling fans in the opposite direction to push heat down from the ceiling.
- Close the flue on any fireplace that’s not in use.
- Call for heating repairs as soon as you notice any issues with your heater.
What type of water heater is the best?
This depends on your household and your water usage. Tankless water heaters are best suited for smaller households that don’t place simultaneous demand on the water heater from several taps at once. Tank water heaters are suitable for many uses and work well for larger households. Heat pump water heaters are excellent options for all-electric homes. Consult with our professionals to find out which water heater best matches your household and budget.

What Does SEER Mean?
