A properly-functioning heating and cooling system is necessary for home comfort and energy efficiency. If you have comfort issues or high energy bills, we can inspect your San Francisco-area home and your heating and cooling system to determine the cause. Kevel Home Performance takes a comprehensive, whole-house approach to comfort and energy efficiency. We identify the root cause of home performance issues and prioritize energy-saving solutions based on building science.



We install a variety of Trane and Bryant furnaces and air conditioners in San Francisco Bay Area homes. With many models to choose from, Kevel Home Performance can work with you to find the right heating and cooling system for your home and budget. We can also air balance your HVAC system and seal your ductwork.


Whole-house fans are an effective and efficient way to cool and ventilate homes, while promoting both home comfort and indoor air quality. These fans draw out heat, moisture, and odors, while bringing in a stream of cool, fresh outdoor air. Whole-house fans typically use 90% less energy to operate than air conditioning systems, significantly lowering your cooling costs. Kevel Home Performance proudly installs AirScape whole house fans.


For your heating and cooling systems to operate properly in San Francisco Bay Area homes, they must be sized properly. Both oversizing and undersizing a system can cause it to use more energy while decreasing home comfort. Kevel Home Performance makes accurate heating and cooling load calculations, as these are the foundation for right-sizing the HVAC equipment and ductwork.

We are also skillful in identifying ways to cut your heating and cooling costs. Kevel Home Performance is certified by the Building Performance Institute and is highly skilled in taking a whole-house approach to energy efficiency.

Our Customers Speak for Us

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.
