Air Conditioning

Air conditioning repair services rank among the most important services you can contract for keeping your Kirkland, WA home safe and comfortable. A good AC repair technician can be trusted to handle the problem properly the first time, to arrive promptly when there’s trouble - especially during a heat wave - and to provide both an accurate estimate and a list of your options. That’s part and parcel of what we offer for every air conditioning repair call! Contact us today for an appointment with one of our professional technicians. 

Ductless Systems

A ductless system provides multiple smaller air conditioning units spaced throughout your home instead of just one. That allows you to reduce the amount of usage in parts of the home that aren’t occupied - or even turn the unit off completely - while still running it in parts of the home you are. That cuts down on your monthly cooling bills! We offer a full range of ductless services. 


When it comes to heating systems, your unit will likely go through very specific phases of its life, all of which will require a trained and experienced technician. It starts when you get a new heater installed, which means choosing the right system and using quality tools and equipment. When your heater is running you need regular maintenance and timely repairs when needed. Finally, the same service should be able to replace you old heater with a new one! Contact us for all your heating needs. 

Indoor Air Quality

If you’re concerned about keeping your home germ-free, consider a UV purifier to help. Ultraviolet light is often used on amusement park rides and at rock concerts to make white clothes glow in the dark. While harmless to us, it’s lethal to germs and bacteria. UV purifiers are placed at the apex of your ducts and kill the germs as your heating and air conditioning unit cycles the air in your home through the system.

Tankless Water Heaters

Tankless water heaters differ greatly from the traditional tank models that everyone is familiar with. They use an entirely different set of principles to heat the water instantly as it flows through the pipes. That means you need a service that understands how tankless water heaters work and can install and repair them with ease, rather than a company that only has experience in tank water heaters.

Commercial HVAC

One of the most important aspects of a commercial HVAC service is the ability to work after hours. That allows them to stay out of the way of your workers and customers while they get the job done. It also means they can perform the work quickly and ensure that any problems with your commercial HVAC system don’t impact the business of doing business. Finally, it means they can arrive anytime, day or night to deal with the unexpected.
