Excellent experience with heat pump installation. Good communication and problem -solving. When a glitch with thermostat occurred 6 weeks later we got a prompt service call, and the tech fixed the issue and showed us what to do should it happen again . Would definitely recommend based on our experience.

Mike did his usual thorough job with my furnace, two water heaters, and a boiler. Ben with Feller for maintenance for many years. Very satisfied.

Wow! We are so impressed! The repairman was on-time, friendly, quick and efficient. He carefully checked that everything was working well (and it was!). The customer service people are very good at their jobs. They listen carefully. They explain well. They are friendly. Thank you. We will definitely use Fellers again.

The technician was very pleasant and helpful advising me about the questions I asked him. He was on time and did a great job on my furnace. This is the second time I have had Feller heating out to my home and both times I received great service and will continue to use them.

Big thanks to Matt at Feller Heating & Air Conditioning ensuring our mini split system is working at peak performance. Matt cleaned and tested the system and installed the heater coil in the heat pump unit. Matt provided excellent customer service and expertise. I would highly recommend Feller Heating & Air Conditioning for installation and service of HVAC systems.

Emergency call on New Years Eve and feller responded as if their own heat was not working. This is not the first time Feller has come through for me in a jam. Really appreciate them. Thanks Matt!

Feller Heating did the annual furnace maintenance today at my place with competence and courtesy. Aaron is a professional technician who is very knowledgeable, courteous, and honest. He notified me when he was coming, arrived on time, took care of business, cleaned up the area after completion, explained what he did, and answered all my questions. It is a perfect service for a fair cost. I highly recommend Feller Heating! A+++++

At first I was unhappy that you sent a different technician. I felt Mike should have come the second time for he knew the situation. That being said , Matt seemed to get with the program and figured how to carry on. I hope my charges will not be increased being Matt may have taken longer?? Seems like the necessary repairs were successful. Thank you Feller Heating. TonyP. S. Please follow up with checking the heating & air conditioning system each year or two with inspections and keeping the system maintained. What would the cost be?

Fast friendly service! Thanks to Matt for giving me a long overdue tutorial on my home heating units…everything is working great now…highly recommend feller !👏👍

Review 10 (2024-12-16 - Rating: 5)
I did quite a bit of research to find the best heating and air company that would not charge me an arm and a leg and that would be reliable and honest. Feller not only met my expectations but far surpassed them. Im so satisfied with their service that I will be sure to use them again.

Review 11 (2024-12-02 - Rating: 5)
The knowledgeable and courteous technician diagnosed the issue of the fireplace flame turning off after running for a short period of time. A new part will be ordered. Feller Heating & Air was recommended by a friend, and they did not disappoint.

Feller Heating did a great job installing our AC. The guys left everything clean and ready to go. Nothing was done sloppy. Thank you!

Can’t say enough nice things about Feller! They’ve been great to work with, and have been understanding dealing with my Uncle who has dementia. Great communication from the office and the technician. I would definitely recommend them!!!

Review 14 (2024-11-05 - Rating: 5)
I am highly satisfied with Feller Heating & Air Conditioning services, which is why they are my “go to” company for all my furnace and water heater needs. They are very professional, provide rapid and very trustworthy service, as well as recommend other service options if they cannot provide it themselves. I highly recommend them!

Review 15 (2024-11-08 - Rating: 5)
Excellent service at fair price. Is there for us in a timely manner for emergencies. We have radiant heat and feel very fortunate to have discovered Mike at Feller Heating.

Review 16 (2024-10-16 - Rating: 5)
Aron from Feller came today to look at my ageing furnace. I learned more about my furnace today than I have in the last 10 years. I appreciate someone who can honestly tell you while showing you what the status of your equipment is, and what to expect in the near future. Also I signed up for the annual service which gives the customer better annual pricing, but I also found out that it did not happen? I have been on a service agreement for about 35 years now. That was when Mr. Feller owned Feller Heating and Air Conditioning? I consider Aron to be the best tech that I have had in a many years. Thank you, Aron.

Review 17 (2024-07-21 - Rating: 5)
From responding to a request for a bid to completion of the heat pump installation Feller has been fantastic. Courteous, excellent communication throughout, minimal interference in our routine during the installation and amazing cleanup at the end. Everything very professional and thorough. Answered all our questions and anticipated and answered some we didnt know to ask along the way. We are very pleased. And cool! Thank you Phillip, John, and crew.

Review 18 (2024-10-31 - Rating: 5)
Aaron did a great job. We needed to trouble shoot the minisplit thermostat and he showed me how to do that myself saving us repairs not needed and money. Efficient and trustworthy.

Review 19 (2024-10-01 - Rating: 5)
Our new heatpump installed by Feller worked admirably for nine months then all of a sudden seemed to become erratic. We played with settings and tried to get it back to normal for more than a week but then gave Feller a call. Within, literally, less than one hour from the time I called, the Feller technician was in our driveway. After checking various digital records he re-booted the entire system and with that got everything back on track. The culprit was unknown but probably a power outage we had experienced some weeks before that took a while to detrimentally affect the system. The system is once again working normally. Thanks Feller.

Feller heating was responsive when my heating system didn’t work properly at the start of the fall season. The technician investigated thoroughly, replaced the faulty parts immediately and then explained options I may want to consider in the future.

Technician arrived on time, was friendly and professional. He tested my furnace and did the annual maintenance as requested. He was knowledgeable and efficient. Highly recommend!

Feller Heating: the ONLY union shop in town that does residential. We want trained techs in our home! In Washington state HVAC businesses arent required to have a specific license that requires training. Feller only has trained, certified techs and installers. AND they make a living wage. Every employee that has entered my home over the last 14 years has been courteous, professional and paid attention to detail. Aaron (our tech today) held to the Feller standard. Bravo!

Review 23 (2024-08-26 - Rating: 5)
Fellers technician came out and did the annual maintenance with competence and courtesy. The tech was knowledgeable and did not try to up-sell anything, but just took care of business. Thank you, Feller!

Review 24 (2024-07-01 - Rating: 5)
Feller helped us with two successful projects. In one they installed dampers in some of our forced air heating/cooling ductwork to moderate flows at certain times. Second, they did trouble shooting and fixed a propane fireplace that had been acting up for years. All of the Feller people I’ve met have been very helpful, polite, and very competent. I am very pleased to have worked with them and will in the future.

Matt was personable, efficient and thorough! Now I’m ready for fall/winter (I think😀). Thanks Feller, appreciate all the excellent service you have provided me all these years.

Review 26 (2024-06-01 - Rating: 5)
Their crew was very proficient and knowledgeable. Feller knew I didn’t have any heat in my house and moved expeditiously to get my new heat pump in. And their bid was the best price for what I needed-they didn’t try to over sell me. I would recommend them any time and will use them in the future for all the maintenance

Review 27 (2024-06-13 - Rating: 5)
We had a flood and needed replacement boiler and hot water heater. Feller did a top notch job on both. Hats off to Mike for a well thought out and implemented install of the new boiler! Solid company, solid crew. Thanks!

Review 28 (2024-07-05 - Rating: 5)
I have a boiler, and whenever there is something I need done, feller always has some one to help. I also had a mini split AC unit installed, and they did a great job, for half the price of Barrons quote.

25 yr old heater finally died on us. Feller came out immediately, gave a quote, had it installed in 2 days. Now we have a heat pump and furnace and a great relationship with the owner, estimator and installers. 100% would recommend Feller.

We had the best experience working with Feller Heating for our mini-split heat pump installation. Highly recommended! At different points in the process we worked with Phillip, Jon, Matt and Mario.

I am impressed with Feller Heating. Should have had hired them at the beginning of heating system install. They know what they are doing and they do the job right. I wish I would have had them hired seven years ago or even little after. This would have saved us ton of cold days and bills. Thank you Feller Heating. Not cheap but worth every $. Its money well spend - I prefer being warm.

We recently had Feller replace our old forced air system with a brand new 98% efficient gas furnace and all new insulated ducting. From start to finish they were easy to deal with and communicated very well. They definitely had my trust throughout the entire process. Lastly, all of their installers were so friendly and knowledgeable. I highly recommend them.

Fellers team recently installed my new American Standard GOLD 96% Furnace and AC system during the two hottest days of the summer, handling the tough conditions like true professionals. I can only imagine how brutal it must have been working in the attic.While there was an issue when the team accidentally scratched my fairly new hardwood flooring, I was impressed with how quickly the situation was handled. Manager Jon immediately arranged for a company to repair the flooring. Robinson’s Hardwood did an excellent job fixing it.Overall, Im extremely satisfied with Fellers service and how they went above and beyond to ensure everything was perfect. Their prices are competitive and reasonable. I highly recommend them!

I highly recommend Feller heating / cooling. I procrastinated getting my forced air furnaced checked and when Nov. Winds hit the furnace motor went out. I called every HVAC company in and around Bellingham and everyone was 1-2 weeks out.Feller squeezed me in a day and got my part ordered and scheduled to fix within next day. Always staying with Feller heating.

Review 67 (2020-01-10 - Rating: 5)
Feller Heating is top notch. They are highly professional, responsive and dedicated to getting the job done right. Because of their expertise, we were able to get off of natural gas and choose much more environmentally responsible option of an all electric heat pump and air conditioner that is 100% efficient. Id highly recommend them for any job you are considering!

Review 68 (2019-10-04 - Rating: 5)
We interviewed three companies and decided to go with Feller because we felt that 1) we were listened to from the beginning - our needs, both long term and short term were taken into consideration, 2) we were given ALL the options for consideration with clear and transparent communication about prices and what was or wasnt included in the cost quoted, 3) even when our install went a little sideways and we were up against a delay, Phillip took extra care to communicate timelines and next steps with us. He really went above and beyond.We are so glad that we chose Feller to work with. Thank you so much!

Arrived on time and respected the current guidelines set in place (mask etc). The assessment was exactly how you’d want it to be, he went right to the furnace and started doing his thing.

We have used Feller before and for this trip they get 5 stars for promptness of service. During a few days of freezing weather the pilot light would not stay lit in a rental house gas fireplace which is the only heat source. We did troubleshoot the best we could but to no avail. Called Feller in the morning and the service man arrived about 2:00 pm and fixed it. Thank you!

FELLER is a real pleasure to work with – – everyone I encountered from estimator to installer, electrician, and coordinator, were professional, helpful, thorough, and thoughtful. They were able to quickly schedule the job – – replacing my old gas furnace and water heater with heat pump and electric water heater – – and completed it in a day and a half, leaving the job site clean and even helping me set up the app on my phone to control the heat pump remotely. They explained everything every step of the way and answered any questions I had. Great guys! Highly recommend.

Our furnace went out unexpectedly. We spoke with Steve at Feller late in the day and he had someone out to look at our furnace the next business day. The tech, Ron, was knowledgeable and efficient with a main priority of restoring our heat. Unfortunately that wasn’t possible due to the age of our furnace. Phillip arrived as the tech was finishing up and quickly got us rolling on choosing a new furnace. Our choices and estimates arrived within a couple of hours and we were able to choose quickly. Due to the cold weather, Phillip moved around some things in his schedule and was able to get the installation done the very next day! We were so impressed with the high level of knowledge, efficiency and care that we were given. In cold weather, when the heat is out and children are involved, it’s an emergent issue and they treated it as such. So grateful for the entire Feller team! We would definitely recommend them for all of your heating and air conditioning needs! We will absolutely be giving them our business in the future.

Happy with replacement of a 20 year old system (infloor heating and hot water) with a Bosch Greenstar Combi 151. Phillip gave us information. Mike installed with care over 3-4 day period, and briefed us on his process. Our boiler room now has space to be a tool room (way less space occupied) and we expect good efficiency this winter.

The requested diagnostic gave me the info I needed to understand my rental home heating system. My very basic questions were well answered and I now know better how to manage the heat, replace the filter, and if needed adjust dampers to individual rooms. I will happily recommend Feller and return for service when needed.
