I needed a full AC/Heater replacement and shopped around local and big box companies in the Bay Area. The owner Josh was super responsive and came out the next day to check out what I needed for my home. He provided me a quote that day and after reviewing 3 other companies it was a no brainer to go with Killen Mechanical. His team came out 4 business days after I signed the agreement and got everything installed in just 6 hours. His whole team was extremely friendly and respectful of my home during the installation process. Couldn't be happier with the price, service, and outcome. Highly recommend you call them before you make your decision.
5 stars! Josh installed two units and a whole house fan. Installation was quick, clean, and handled with real expertise. Everything was explained clearly, and the work area was left spotless. The way we had things set up did not make sense, and Josh was able to figure everything out and recommend the best solutions. Highly recommend, and I’ll definitely be using them again in the future.
This company is exceptionally detail oriented. I used them for servicing my AC a couple of times and was happy with the service (and the price) so used them to replace my old AC (2 of them) when it was needed. They did exceptional work with a great price. These folks are my “go-to” for all things HVAC related. I should also note that they gave me options on the AC replacement which allowed me to pick an option that fit my budget! Highly recommended them.
As the owner of an HVAC company myself, I’m very selective about who I refer customers to when a project falls outside of my service area. Killen Mechanical is one of the few heating and air conditioning companies I confidently recommend. Their team is professional, knowledgeable, and committed to doing quality work the right way. Whether it’s air conditioning repair, furnace replacement, heat pump installation, preventative maintenance, or complete HVAC system upgrades, they consistently provide excellent service and clear communication. In our industry, your reputation is everything. That’s why I have no problem sending customers their way. The feedback I’ve received has always been positive, with clients praising their honesty, workmanship, responsiveness, and attention to detail. If you’re looking for a reliable HVAC contractor who genuinely cares about customer satisfaction and delivers high-quality heating and cooling services, I highly recommend Killen Mechanical.
Killen Mechanical sets a high bar. I have worked with a lot of different HVAC companies throughout the years and these guys are by a far the best. Josh Killen has been there for us at multiple residential properties that we own- from emergency repair, to full replacement. In addition to having a terrific response rate, sense of urgency and clear communication - is the level of expertise he has of the latest and most efficient products in HVAC. You are getting top of the line in technology, and installation - improving how efficiently your system runs is priceless. Killen Mechanical has always been top notch - I highly recommend.
