Our Mission: Comfortable Homes & Happier Customers


When we started Ultimate Comfort, we knew we wanted to create a company that provided the quality products and solutions needed to make our customer’s lives more comfortable. We also wanted to create a company with exceptional customer service—one that reflected our values of treating people fairly and honestly, and our belief that success comes from helping people solve problems and find solutions.

Above all, we imagined a company that listened to our customers and made the best possible recommendations for meeting your needs. A company that ensured your comfort from our very first meeting to your final “ah…” when you experience the warmth of your new heater on a January night, cool air from your AC in August, or when you relax in a warm bath.

For us, the relationships we build with customers are as important to us as the solutions we provide. We look forward to meeting you and finding out how we can help you live and work more comfortably.

Our Values

  • ribbon-1


    Whether it’s the great service we provide, the honest recommendations we give, or our quality guarantee, we believe in doing right by our customers and going the extra mile to ensure the job is done right. We do free site visits for every project, no matter the size, to make sure we have a clear understanding of your needs and can provide accurate estimates. We’ll always stick to our bids, so you can stick to your budget—and if there are any flaws in our workmanship, we’ll fix it fast and free, with no questions asked.

  • book-1


    Too many companies think of sales first, customers second, so they pressure people into buying products that may not be a good fit. At Ultimate Comfort, we want to help you make the absolute best decisions for your home and budget. We promise to provide you with honest recommendations, fair pricing, and the support you need to choose the best solution for your needs.

  • hearts


    As a partner of Energy Trust of Oregon, we carry an extensive line of energy efficient heating and cooling products that can reduce your carbon footprint and your utility bill. If you’re looking for energy efficient products, we’re committed to helping you find the best options for your home and budget.

  • aircon-1


    At Ultimate Comfort, we take comfort to mean so much more than being warm on a winter evening or cool on a hot summer day. It means that you’re as comfortable working with us as you are with the solutions we provide. It means the comfort of being listened to and treated well. And it means the peace of mind that comes from knowing that you made the right choice.
