Commercial HVAC
Design and Build Services

Our commitment to your commercial HVAC design & build goes far beyond merely meeting a schedule and staying within a budget. Before we cut a single piece of sheet metal, we carefully plan every aspect of the job, coordinating with other trades and figuring out the smallest details in advance.

Project Management

Our job is to make your projects go smoothly. If your project is not properly managed, a lot of things can go wrong: costs overruns, schedule slip, building occupants complain, and efficiencies are lost.

At Home Comfort Alliance, we understand, which is why we take a proactive and comprehensive approach to defining, designing, and delivering every project. We provide professional, trusted advisors. Our mission is to ensure that your projects run smoothly. When a project isn’t effectively managed, various issues can arise: costs can exceed budgets, timelines can be delayed, building occupants may voice complaints, and overall efficiency can be compromised.

At Home Comfort Alliance, we recognize these challenges. That’s why we take a proactive and comprehensive approach to defining, designing, and delivering every project. Our professional and trusted project management services are tailored to meet and exceed your expectations every time. With over 50 years of experience specializing in HVAC-related projects, we understand buildings and know how to complete projects on time and within budget.

Comfortable Environments. Efficient Projects. Energy Savings. Tenant Satisfaction. If these are your priorities, reach out to the company you can trust: Home Comfort Alliance.

Response from the owner:Thank you for your kind words, Gail! I’m delighted to hear that Allen provided a wonderful and professional service. We’ll be sure to assign him for your next appointment.

First-time home buyer and recently just moved in. We purchased through Costco and got a fantastic rebate. The experience has been good throughout. I was shocked at how prompt and responsive the entire process was; I’m not used to companies being so on top of things. Ruslan Klimansky & Antonio Salazar were outstanding to work with while installing our new heat pump. They were on time, professional, willing to explain each part of the process, put on all the finishing touches, and resolved any issues. We’ve only had the new unit a few days, but so far it’s keeping us plenty warm through this burst of cold. We would recommend this company to our friends.
Response from the owner:Thank you for your 5-star rating, Colin! We’re glad to know you had a positive experience with Home Comfort Alliance – Redmond. If there’s anything else we can assist you with, feel free to reach out.

Evan came to clean my dryer vent after my dryer was sending an error code due to a blockage. He arrived on time, explained the process, completed the cleaning, and left my laundry room cleaner than it was when he got there! Very personable guy, too. Highly recommend Home Comfort Alliance!

The technician (Reylli Myers) was friendly, knowledgeable, and thorough. They clearly explained the condition of our HVAC ducts and dryer vent, and the work was done efficiently and professionally. I especially appreciated the thoughtful recommendations they shared for improving air quality in our home—practical, not pushy, and genuinely helpful. We’re seriously considering the next steps they suggested. Highly recommend.
