If your system is nearing the end of its lifespan, we'll help you determine whether repairing or replacing the equipment is the better long-term investment.

Air Conditioning Repair & Installation

While Western Washington has traditionally been known for mild summers, many homeowners now rely on dependable cooling during periods of higher temperatures. Our cooling services include:

Air Conditioner Repair: We'll diagnose refrigerant issues, electrical failures, airflow restrictions, frozen coils, compressor problems, and other common AC concerns.

Air Conditioner Installation: Whether you're replacing an older system or installing central air for the first time, we'll recommend equipment that fits your home's size and comfort goals.

Heat Pump Cooling: Heat pumps provide efficient cooling during the summer while also serving as your heating system during colder months.

HVAC Solutions for Rural & Hillside Properties

Many homes in this area sit on larger lots with mature trees, rolling terrain, or tucked-away locations near May Valley and Cougar Mountain. Some properties have been remodeled over the years, while others have retained much of their original character. Those differences can affect how a heating and cooling system performs.

Factors like multiple additions, detached garages, finished basements, varying insulation levels, and changing airflow needs all play a role in designing an effective HVAC solution.

Rather than recommending the same equipment for every home, we evaluate your property's layout, comfort concerns, and existing system before making recommendations tailored to your needs.

Preventative Maintenance for Year-Round Reliability

The best time to schedule HVAC service is before your system stops working. Routine maintenance helps identify worn components, improve operating efficiency, and reduce the likelihood of unexpected breakdowns during peak heating or cooling seasons.

Our maintenance visits may include:

System inspection
Airflow evaluation
Safety testing
Performance checks
Cleaning of applicable components
Recommendations for future repairs when necessary

Preventative maintenance helps homeowners protect one of the most important systems in their home while extending equipment life.

Quick, knowledgeable, and resolved a complex issue that wasn’t obvious from the start. Was able to avoid what could have been a more expensive issue.

Joseph and Josh installed a new furnace and they exceeded my expectations by going the extra mile and answering all my questions and custom bending the exhaust pipe and cold air return to make it all fit, look nice and left no mess. I would recommend one hour heating to grandma and all my friends...Plus the price was very reasonable. Their manager even came by twice to check out the job while they installed it. Great work and great service with a smile...

I have owned a mini split system for 5 years with multiple heads. I have had 4 different hvac techs out to work on it. They could never get it to work right. Jeffery with One Hour came out figured out the problem. Rewired the units and it has never worked better. They did a great job! I will be using them in the future. Highly Reccommend!!!

Wow! What exceptional customer service. From the moment they answered the phone I knew I had made the right choice. The representative I talked to was so friendly and knowledgeable and willing to work with my schedule. That of course was only the beginning. The technician who showed up was clean cut and dressed very neatly. Putting his shoe covers on first thing to protect my home. I told him it wasn’t necessary but he insisted. Instead of just jumping into the repair like previous companies I dealt with. He took the time to ask me several questions about what was currently happening and the history of my equipment. He then proceeded to explain the whole process of how the call would go. Once he was finished with the diagnostic, which was very thorough I might add. He then asked if it was ok to present a few different options. Educating me in detail on each option, but never trying to sell or lead me. It was very low pressure. Well I picked the right option for me and my system is working better than ever. 5 stars service start to finish, Great job guys,

Colin was great! Very knowledgeable and gave us peace of mind that the AC would be repaired. He was very professional and talked us through each step of process. He completed the job in a very timely manner and got us back on track. Thank you Colin and I would definitely recommend and use this company again if the need arises.
