I just wanted to let you know that Genaro did a great job. It was definitely not easy as I had expected, but he took his time and fit everything in and did it correctly. A lot of people would have rushed or hacked through it. He also went above and beyond what he needed to do by taping up some unsealed seams around the furnace. He did not have to do that as it had nothing to do with the dampers, but he did! That’s great customer service and workmanship. Please let Genaro know I was very pleased with his work. I will definitely be recommending you to anybody I run across that needs HVAC work.


Just a short note to say Thank You for the fine job you and your crew did installing our new furnace and A/C units. I was very impressed at how hard the crew worked. They were professional, courteous, and answered all of our questions, explaining some of the work being performed. I will definitely recommend your company to anyone needing Heating and A/C services.

Thank you for your great service! I will recommend you to anyone I know who need your services.

Dennis G.

Thank you for your wonderful work. It sure has made my home a “warmer” yet “efficient” place to be.

We haven’t had an occasion to use the A/C, but the furnace is “whisper” quiet. The guys did a great job cleaning up, too.

After having a disappointing experience with another AC repair company, I found JW Hanson Heating & Air. Kim was very friendly and helpful in scheduling the appointment. It took a few visits to get my AC back up and running, however, they did not charge me for the additional trips. Overall I was pleased with their service and would recommend them to others.

Called Kim @ JW Hanson because we had no heat in our house. Major issue since my wife is 8.5 months pregnant. She was able to arrange an appointment for the next morning at 7:30 AM. She was extremely sympathetic of the situation and re-arranged schedules to accommodate us.

Jason, her service guy, showed up at 7:25AM. He was professional and skilled. Methodical about trouble shooting the problem and able to identify and resolve the issue in 1.5 hrs. He even had recommendations about how to maintain and extend the life our furnace.

Couldn’t be happier about the results and will only use them in the future. I’ve used Yelp in the past and read reviews, but never posted before. The experience was so good it motivated me to submit my first Yelp review. Use them!

Will Hanson finished doing a repair of my 10 yr old furnace in less than an hour. There was no trying to sell me something I did not need. He was efficient and helpful in explaining the functions of my furnace and its repair needs. I felt that he was very skilled and professional with this repair and the other questions that I asked him. I recommend this company for your heating and air needs. There are too many HVAC companies out there willing to sell you a new unit when you do not need one. Call them for your repair or new furnace/ac needs. You will not be disappointed.

We called when our heater was blowing only cold air. We called on a Monday afternoon, and had an appointment for the next day!

The technician, John, was professional, courteous and very knowledgable. He diagnosed the problem quickly, located a part with the help of Kim in their office. He returned later with the part and installed it quickly.

The heater is working again! Thanks so much Hanson Heating and Air. GREAT company to work with!!

My mother-in-law’s AC unit went out last night, and with temperatures in the high 90s (and she’s in a wheelchair) we were very concerned. We called JW Hanson and Will came out this afternoon. He identified the problem right away and had it fixed in well under an hour. Thanks AGAIN for the help, they are a class act!

John H.

My AC unit needed service as it was not cooling off the house at all. Called in the morning and they were able to come at same day. They did a great job checking everything out. AC unit needed some more refrigerant and now it is back up and running. Cool! Very Cool.

We’ve got a pretty complicated hydronic/solar/propane water heater and Will knew exactly what was wrong and how to fix everything. He’s very professional and a perfectionist which is what you want when it comes to plumbing.

We are in the midst of an extremely complicated overhaul of our existing radiant heating system. The company who originally installed it and recently serviced it overlooked some alarmingly dangerous safety issues. Will Hanson identified the problems and offerred solutions at very reasonable rates. He and Kim have been continuously available either by email or cell phone to answer questions and troubleshoot until he is able to be on site, which has always been the same day I’ve called. Though we are not yet finished with the overhaul, I have complete confidence in his ability and knowledge to make our system function at the optimal safe level. I would wholeheartedly recommend JW Hanson for your HVAC needs and will update again once our project is complete.

We chose JW Hanson to do our furnace and duct replacement our recently-purchased 60-year old house with a failing 30-year old furnace. After talking to 3 companies about this job, all of which came in with approximately the same price range and strategy, we went with Hanson because Will (owner) and Travis gave us the most detailed analysis of the options we had for getting the old furnace relocated from the crawl space — and they were the only ones to actually go in under the house to check out the current situation (about 10-15 feet under in a small space). Demolition/removal of the old furnace and ducting, and then the installation of the new system (based in the attic now) went very smoothly with Will, Travis (mainly), Manuel, and John collaborating on this over 3-4 days. Kim’s coordination from the office was a great help, too. Inspection went smoothly, and the team took the time to fix up a few last details on the ducting that we never would have known about, so we appreciate their integrity as well. This was hard, dirty work since so much of it involved working under the house and in the attic. Overall, we got great attention to detail and a safe, clean, efficient job.

Our heater went out and the usual people weren’t readily available. I called Hanson after reading the yelp reviews and I will never dial the old number again! The guy showed up precisely at the arranged hour. He was polite, efficient and reasonably priced. The heater worked fine until the chilly evening when it wouldn’t go on. The owner showed up the next morning with a temporary remedy and an order for a new part. That remedy also failed on that night. We got home at 9:00 PM the following night and two of their trucks were in the dark driveway. They rush ordered the part and both men showed up to be sure they got it right. It’s humming along like it was brand new. Seeing how they problem solved and went out of their way to be sure it was repaired immediately was very impressive. I don’t know how they could have been better. Highest recommendations for these people.

Ken B.

As always I tend to trust Yelp reviews and this was no different. From the first conversation to the end of the service call, I was nothing but impressed. I would highly recommend JW Hanson Heating and Air. We will definitely use their services in the future for a biannual service checkup.

Julie M.

I called JW Hanson because of the great reviews on Yelp, and I was not disappointed. Like the others have stated, from the first phone call to paying the bill at the end, I was impressed.

Our heater has never worked efficiently, and when our thermostat broke a month ago, I knew we needed to bite the bullet and finally get the furnace serviced. Now, our furnace works great. I didn’t realize how inconveniently we’d been living all these years! Our house temperature stays at a comfortable level, and the system seems to be quieter overall. Best of all, the service cost was very reasonable.

Thank you, Jason, for your excellent service.
