Reviews of local pros in Cornelius, Oregon

Williams & Sons Heating & Air Conditioning installed our original Carrier Weatherbeater 9200 furnace over 21 years ago. when we bought our home, we started noticing some heating problems. the secondary heat exchanger was having trouble, so we decided to have the furnace replaced. the service we got was excellent—really friendly and professional. their team gave us a full and honest look at what needed to be fixed, then handled the job quickly and efficiently. i really liked how cesar took the time to explain all the details about the new hvac system and answered all our questions. you can definitely count on them for reliable and knowledgeable help with heating and air conditioning.

I have been using Williams & Sons Heating & Air Conditioning for many years. Their service is always excellent, and they respond quickly whenever I have a furnace emergency. They have replaced the furnace systems in two of my homes and also take care of the regular maintenance each year. I appreciate how they remind me when it’s time to have my furnace and air conditioning checked. Jalen recently did a thorough inspection of my furnace and explained everything clearly. I highly recommend their services.

I had a fantastic experience with this HVAC company in Cornelius! Ruben was extremely knowledgeable, patient, and helpful. As a first-time homeowner, dealing with heating and cooling system issues can feel overwhelming, but Ruben took the time to explain everything about maintaining our AC unit and what signs to watch for. If you want a team that clearly explains your HVAC concerns and walks you through the solutions, this is the company to call. Ruben got our air conditioning system running smoothly again and the cost was very reasonable. We’ll definitely use their services again!

Danny is an honest and professional technician who really knows heater repair. I first met him when he worked for another big company in the area, and I was always happy when he came to help because of his friendly attitude and skill. When I found out he started his own business, I made sure to contact him to take care of our heater. Danny quickly diagnosed the problem and fixed our heating system so it now works perfectly. He also took care of registering the replacement part for the warranty, which he did as part of his regular service without me even asking. Every time he came into the house, he wore shoe covers to keep things clean, which shows how much he respects his customers’ homes. His prices are very fair, and you can tell he cares about doing the job right. If you need someone trustworthy, knowledgeable, and respectful to repair your heater, Danny is a great choice. He even followed up with a call to make sure our heater was working well. I highly recommend this company for anyone needing heater repair—you’ll be very happy with their service!

We had a fantastic experience with our furnace repair and replacement in Cornelius! After getting several quotes from different companies, this team stood out as the one we felt truly comfortable with for replacing our two old furnaces, as well as handling our air conditioning and humidifier upgrades. Ruben and his crew took care of everything, including updating some of our ductwork and making sure all the electrical and plumbing for the new humidifiers was up to code. From the first meeting, there were no pushy sales tactics—just honest advice and clear answers to our questions. The technicians were always professional, letting us know before they arrived each day and keeping us informed throughout the whole process. They worked steadily until the job was finished, and the installation went smoothly without disrupting our daily routine. They also made sure to clean up and remove all the old equipment and debris when they were done. The price we were quoted was exactly what we paid—no surprises.

Ruben and Elias are skilled heater repair technicians that I would recommend for any heating system needs.

Throughout the process, they patiently answered all our questions and even gave us a helpful walkthrough on how to use the new smart thermostat. I highly recommend their services for anyone needing heater repair or installation.

We hired a local company in Cornelius for heater repair and installation in a custom home my son built for his family. making the home energy efficient was really important to us. danny helped us from the very beginning, making sure we picked the best heating system for our needs, and he really knew all the different options out there. we had danny and his team handle all the heater work for the house, including in-floor heating, mini-splits, and a high efficiency boiler. i’m amazed at how quiet and comfortable the house feels now. the utility bills are even lower than we expected. you can tell they take a lot of pride in their work—the mechanical room looks great and my son loves showing it off. everyone on danny’s team, from the office staff to the technicians working on the house, was very professional and friendly. they made the whole process smooth and were always patient, especially when weather slowed things down. as we got closer to moving in, they made sure to finish everything on time. pricing was fair and upfront for the high quality of work we received. i highly recommend this company if you need heater repair or installation in Cornelius.

I contacted Williams & Sons Heating & Air Conditioning because my AC unit had a strange burning smell. Jalen arrived right on time and was very professional throughout the whole visit. He made sure to cover his shoes before coming inside and wore a mask, which I really appreciated. Jalen took his time inspecting my air conditioner, carefully checking everything to find out exactly what was wrong. He didn’t try to sell me any unnecessary parts or services, and explained everything clearly. I’m very happy with the honest and thorough work. I’ll definitely call again if I have any heating or cooling issues in Cornelius. Great service!

I recently had my AC installed in Cornelius and wanted to share my great experience. Brady came out and gave us a clear price, and the installation happened the very next day. The whole process was smooth—Brady and his team were friendly, tidy, and made sure everything was done right. Our new AC unit works perfectly and keeps the house cool, which is a must in the warmer months here. There was one time I needed help because I made a mistake with the settings, but they responded really quickly and got everything running again without any hassle. I also called back for some AC vent work, and Elias was very polite and helpful on the phone, making it easy to schedule a visit. Cesar arrived early the next morning and fixed the issue fast. This company always goes the extra mile for their customers. The staff are pleasant to talk to, work neatly in your home, and really care about doing a good job. If you need AC repair or a new AC unit in Cornelius, I definitely recommend them!

I recently had a safety issue with the heat exchanger in my furnace, which was found during a regular inspection by another company. They gave me a repair estimate that was almost as much as buying a new furnace. Wanting to be sure, I decided to get a second opinion and reached out for help. Jordan came out the very next day, confirmed the heat exchanger problem, and ended up installing a new furnace for nearly $1,000 less than what I was originally quoted for just the repair. The service was fast, affordable, and focused on making sure everything was safe and working properly. I was really impressed by how smoothly the whole process went and how much they cared about customer satisfaction. I highly recommend this company to anyone needing reliable furnace repair or installation in the area.
