Which type of water heater is best for living in Washington?

Both tank and tankless water heaters work well for Washington. The type of water heater that best fits the individual needs of a home are different, however, so we recommend you work with our professionals to find what water heater model is ideal. Tankless water heaters tend to work better for smaller households where there aren’t multiple hot water taps on at one time.

How often should I be replacing my furnace filter?

This filter needs to be changed every 1 to 3 months while the furnace is in regular use. Simple panel filters need to be changed most often, while stronger pleated filters and media filters will need less frequent replacements.

What does your AC installation process in Bellevue look like?

After first meeting with you, our technicians will perform a load calculation to determine how much cooling power your house requires. We’ll find the right size unit based on this calculation as well as your input on what features you want. On the day of the installation, we’ll first remove your current AC (if you have one) for recycling, then put in the new unit, connect it to the ductwork and power, and test it. The process will take a few hours.

How long does a water heater last in Washington?

A tank water heater will last for 10–12 years, and a tankless water heater can last for 20 years.

What are the benefits of a ductless system?

  • Can be easily installed in homes that lack ductwork
  • Higher energy efficiency than ducted systems
  • Flexible for targeting hard to heat-and-cool areas and for add-on rooms and room conversions
  • Zone control—only heat and cool the rooms that need it
  • Improved indoor air quality

What are some signs that I might need a new water heater?

  • The volume of hot water has dropped
  • Water won’t get as hot as it used to
  • Reddish discoloration in the hot water
  • Corrosion on the water heater
  • Large increase in your heating costs
  • The unit is past its manufacturer’s estimated service life

What brand of equipment do you work on?

What is the price of a tune-up?

$179

What kind of payments can the tech take? Can they take cash?

Our technicians can take cash, checks or credit cards

Do you carry parts at your location for purchase?

Sorry, we do not.

Do we do duct cleaning?

Although we offer several services for ducts, we do not offer duct cleaning.

What is the lifespan of my HVAC system?

This depends on the type you have and how often it receives maintenance (we recommend each HVAC system have maintenance annually). Here are estimates for several systems with regular maintenance:

  • Gas furnace: 15 years
  • Electric furnace: 20 years
  • Central air conditioner: 10–15 years
  • Heat pump: 10–15 years
