We love our customers... and we think they like us too! See what they have to say:

Very professional and knowledgeable, excellent customer service. With a new baby, improving the indoor air quality and thermal comfort of our home was a priority - Kevel delivered with great work completed in a timely manner and on budget.

Graham, San Francisco, CA

My house was very drafty with no working heat before Kevel came. Now, our formerly broken central heating is working great, and I notice a significant decrease in drafts throughout. I would say that Kevel is very responsive and responsible.

Koralle, Berkeley, CA

Excellent workmanship and attention to detail--as well as to our questions. The understanding of the whole house energy system was exceptional, and the "as-built" system diagrams were a real plus.

William, San Rafael, CA

Very professional, knowledgeable, pleasant to work with. They found several major problems with our ductwork that have been around for at least 30 years. Noticing a difference already in how the house seems better able to maintain a constant temperature.

David, San Anselmo, CA

Great workmanship and completed in a timely manner by conscientious people. My home temperature is uniform throughout, before the upgrade the downstairs was always a lot colder.

Barry, Mill Valley, CA

Everyone was very friendly, considerate about tracking dirt into the house, kept worksite neat - not to mention did a great job. Brian even came one evening to fix the furnace door which came unlatched so that I could have heat.

Kay, San Rafael, CA

I am very happy with the efficiency, the fit, the look, and the partial sound reduction. Indow Windows are a very good product with obvious benefits. Kevel provided very knowledgeable and professional service.

Laura, San Francisco, CA

Feels like a whole different house. No longer do I wake up feeling like I'm camping (i.e. with chilly air feeling like I'm outside). The air sealing I think made the most difference - much more than I had expected.
