Kevin helped me install two Fujitsu Halcyon xltH 9K and 15K mini splits - one in our livingroom and the other in our master bedroom. I did my research and I learned flaring the freon linesets is a critical step. Done wrong and the system will leak freon and the system will under perform. Replacing the freon will cost you hundreds of dollars later on. I wanted someone willing to use the right tools and follow best practices. Kevin was the right person for the job. I had a date I needed the work to start and he was able to make that work with his schedule. When installing the system, he took the time to explain what he was doing and why. For example, while it is satisfactory to vacuum the lines down to a reading 500, Kevin kept going and we wound up with a reading of 250. This extracts more moisture from the system, which improves performance and should protect compressor from damage later. I will call Kevin when I am ready to expand my Fujitsu system to the other bedrooms. I highly recommend Kevin he is a hard work, who knows what he is doing and take pride in the work he does. You can't go wrong with Kevin. read more

Kevin Williams, the owner of Williams Heating and Air, provides outstanding service! Our furnace failed on a Saturday during this winter. We actually had CO enter the house and set off the CO detector. I called Kevin on the Saturday my furnace kicked the bucket. He was out to our house within an hour. He determined that the heat exchanger cracked and was the cause of the problem. Since our heating system was fairly old, it was not cost effective to repair it. Kevin installed a new furnace within a few days at a very reasonable cost. He also reconfigured some of the ducting to more evenly distribute air flow throughout my home. Kevin also took care of filing for a permit with the County and was present during all inspections. I will always use Kevin for all my HVAC needs. Very honest and competitively priced. Additionally, the new appliance came with an outstanding warranty! read more

I first met Kevin Williams 3 years ago when he worked for another company. He impressed me right away with his knowledge and capability. I could tell his professional standards were high, and he took the time to explain everything. Recently my HVAC system was "acting up". I received 3 failed service calls from a new company. I called Kevin as I realized I had saved his cell number from the original installation. Luckily, he has a new business of his own, I was immediately relieved. On his visit I explained my situation and he quickly diagnosed how to solve my problem. Everything is working great now. I won't call anybody else when I have heating or cooling issues. Williams Heating and Air is my first choice. read more

Thank you Kevin for giving me more than 1 reason and the confidence to recommend you to everyone read more

Being new to the area we reached out on the community peeps page asking for a recommendation for a good HVAC company. Immediately got 2 responses both said Williams Heating and Air so I called.

He found the leak quickly and resolved the issue then proceeded to do the complete HVAC preventative maintenance. He is super knowledgeable and eager to answer any questions. I would recommend him to everyone, including my Grandmother !!! read more

Kevin was awesome! Our heating stopped working yesterday and with three children in the house (2 under 2 years old), we needed a miracle to get it up and running quickly. We looked on Facebook and someone recommended Williams Heating and air. He contacted us shortly after and set up an appointment for the same day! He not only fixed the problem, he also checked out the entire system, cleaned the coils and fixed a couple of extra issues we didn't even know existed. I am so grateful for the service and caring he showed my family. He is polite and knowledgeable and I would recommend him highly! read more

This guy was the best! This is going to be the first guy I call any time I need HVAC work done. Two weeks ago I had ABT come in to fix our heater. They did little more than restart the systems and replace filter and leave me with a bill. Yesterday my system went down again, and Williams was quick to respond, do thorough diagnostics, actually pinpoint the cause of the failure. He walked me through the process of maintaining our system and gave me a clear path to get the repairs I needed. If you need help with your heating and air, I highly recommend calling Williams first. read more

What a great experience! Williams Heating and Air is 100% the right choice for anyone looking for HVAC repair or work in the Nevada County area. Kevin not only fixed our Air Conditioner the SAME DAY that I found that our unit was not working, but his cost was half of what I had expected. On top of that he taught me a lot about our HVAC system, and A/C systems in general, while he gave me a rundown of what our specific problem was. I really can't recommend Kevin enough... give Williams Heating and Air your business and you will not be disappointed! read more

Williams Heating and Air is now my first choice for all my HVAC needs. I was referred to Kevin from a friend and couldn't be happier. I was doing a kitchen remodel and needed some vents moved and a hood installed. Much of the work is under the house with tight crawlspace. He made all the changes look great. He even checked my AC unit and found it to be in dire need of cleaning and gave me tips on how to keep it running good. He was always very courteous and would call or text before arriving. I will definitely call him again for any hvac work. read more

I cannot say enough good things about these guys. Kevin is extremely knowledgeable and thorough. He was able quickly diagnose why my furnace had low air flow and would drip water when the AC was on. Not only that, but he was able to resolve the issue over the phone from over 400 miles away! He clearly explained everything that was happening and I learned a ton about how AC units work. Now my house is cool and drip free. I would recommend these guys in a heartbeat. read more
