Air Conditioning

We have comparatively mild summers in the Bothell, WA area, but that doesn’t mean we don’t have regular need for our air conditioning systems. When yours breaks down in the middle of a heat wave, you need a repair service to move quickly to get it fixed.

That’s why we offer emergency services and can be available anytime, day or night, to handle your air conditioning issue. That way, we can get your system up and running again quickly!

Ductless Systems

Centralized air conditioning systems are very inexpensive and effective to use, which is why they’re so popular. However there are other options if a ducted system isn’t right for your home. Ductless mini split systems divide the load between multiple small units in your home, letting you set the temperature for different parts of your home separately.


There can be a temptation on the part of do–it–yourselfers to attempt to repair a troublesome furnace or other form of heater themselves. This is a big mistake. Heating systems are complicated and involve potentially dangerous components such as gas lines. That requires formal training and licensing from the state to properly diagnose and repair.

Instead of attempting to fix the problem yourself, call our trained team for quality heating repairs you can count on every time!

Indoor Air Quality

Most homeowners in the area quite rightly focus on temperature control when it comes to a comfortable home. But that’s not the only aspect of your household atmosphere that contributes to a happy environment. Indoor air quality is a factor as well: humidity levels, mustiness, the presence of germs in the air and other factors.

An air purification device installed in your HVAC system can address those concerns, helping your home feel more comfortable and your family live healthier.

Water Heaters

Your water heater is likely located in an out–of–the–way part of your home: in the basement, the garage, or perhaps a dedicated closet. It often does its job very quietly, which means it can be hard to spot serious problems with it until it’s too late.

Learn to look for signs of water heater trouble early, then call in a repair service when you spot them. They can include anything from strange noises to water that doesn’t stay hot!

Commercial HVAC

Commercial HVAC systems are a key part of your business, and you can’t afford for yours to go down for even a short amount of time. Doing so can cost you lost productively, turn away potential customers, and even damage key components to your business such as computers.

Look for a qualified commercial HVAC service to perform repairs and conduct regular maintenance sessions that stops potential repair issues before they start. That way, your business will keep running smoothly!
