Furnace maintenance

Detecting minor issues during routine annual furnace maintenance improves safety, saves money, and prevents breakdowns when it is cold outside. Our technician will thoroughly check your gas or electric furnace components and connections, lubricate moving parts, and test system controls and thermostat calibration. Maintenance service also includes a visual inspection of ducts, and high-quality filter replacement to ensure healthy air flow.

Gas furnaces should be checked at least once a year by our trained technician to ensure maximum efficiency and safety. Natural gas furnaces use combustion to create heat, and the process produces a small amount of carbon monoxide that gets vented safely when the system is working properly. Annual maintenance of your gas furnace by our certified technician includes:

  • Clearing fresh air intake of blockages
  • Ensuring tight seal on blower door
  • Analyzing combustion and making adjustments or repairs to be within manufacturer’s specifications
  • Checking components and wiring for damage that could cause safety issues
  • Check system for proper operation
  • Clean or replace filters
  • Clean condensation drain
  • Clean burners and flame sensor
  • Check blower motor bearings, function, and amp draw
  • Inspect blower wheel
  • Check and adjust gas pressure
  • Inspect heat exchanger for corrosion or cracks
  • Check all wiring, safety switches, and safety controls
  • Inspect all vent pipe, condensation drains, and external furnace related devises
  • Make recommendations to correct any observed problems


Fireplace inspection and maintenance

A gas fireplace is unlikely to be your main source of heat for the winter, but annual inspection and maintenance by our qualified service technician is still beneficial for safety and efficiency. A quick check-up of your family’s fireplace can catch any problems before there is a safety concern and at a lower cost than an emergency repair bill.

Did you know that gas logs should not be moved or cleaned by anyone that is not a qualified service technician? Gas logs should never be sprayed with cleaners for safety. If your gas logs need cleaned give us a call.


  • Pro tip: Replace the batteries in your fireplace remote twice a year. A good rule is to change these batteries when you change the batteries in your smoke and carbon monoxide detectors.

Heat Pump Maintenance

Winters in the valley along the I-5 corridor are relatively mild, and many residents choose a heat pump instead of a furnace. Utilize a heat pump to heat and cool is efficient and saves money. Maintenance for your heat pump in fall for a heating tune-up and spring for a cooling check-up will help us make sure you are comfortable in your home all year.

Our trained technician will check the overall health of your heat pump and airflow. Maintenance will also include checking the indoor coil, outdoor condenser, blower and fan alignment, coil fins, electrical wiring, and other components to ensure safe and efficient use of your heat pump for the coming season.

Change Air Filters

One of the best maintenance practices is to replace filters in your HVAC system at least twice per year. Changing filters helps keep your air clean, but it also keeps your system clean. A clogged filter can significantly reduce the efficiency of your furnace or air conditioner because it has to work harder to supply air to all the rooms. Contaminants that would normally be caught by a clean filter can cause problems in furnace components when the filter is not working properly.

Pollen, pet dander, bacteria and other contaminants that are not caught by the dirty filter travel through the duct system throughout the home. Our trained technician will remove used filters, and install new filters that are the best fit for your HVAC system. You can breathe easy knowing your HVAC system and indoor air are protected with a clean filter of your choice.

Many heating and cooling systems support air filters with a high MERV (Minimum Efficiency Reporting Value) rating. MERV filters with higher ratings trap smaller particles as the air travels into the system preventing dust, spores, and other contaminant particles from spreading through the system. We recommend MERV rated filters but it is always your choice. Talk with your technician today to learn more about the filter options that are the best fit for your HVAC system.

Indoor Air Quality

UV Air Purification

Ultraviolet (UV) air purifiers are a safe and powerful way to remove airborne and surface contaminants as air passes through the HVAC system. We install, service, and maintain a range of UV air purifiers for home and commercial HVAC systems to meet your indoor air needs. Our most popular UV air purifier is scientifically proven to remove allergens, break down viruses, and kill 99.9% of bacteria. Some of our air purifier models also reduce odors and remove harmful gases. This amazing technology is used in schools, hospitals, and office buildings around the globe.

Electronic Air Cleaners


We offer EAC’s (electronic air cleaners). These washable metal filters are installed into your ductwork and can be taken out and cleaned.

Duct Cleaning


Cleaning the duct system is beneficial for health, indoor air quality and increased efficiency of your heating and cooling systems. A comprehensive evaluation of the current condition of your heating, ventilation and air conditioning ducts by a professional technician is recommended for the health of your HVAC system every five years. Duct cleaning removes contaminants like allergens, dust and debris that build up over time in the duct system. We offer professional residential, commercial and duct cleaning services.
