Technician was very knowledgeable. Was very helpful. He recommended another vender when he realized his servers were an over kill. When does that ever happen? read more

Great work and highly recommended. We'd had some issues with underfloor heating, but everything is great now, thanks to them.

The technician was terrific, but. First they charged me $1,800.00 labor to install a part under warranty. It took just under 3 hours. That's $600.00 an hour. WOW! Then they had to replace another part, a valve. Took 20 minutes. Labor $369.92. Double wow. On a five year old furnace. Unreliable TraneXR95 Product, crazy labor rates read more

Trevor in customer service is AWESOME! I've used Foss Heating before and the service was great and price for a thermostat was really reasonable. Today I called to get a quote on moving a gas range which would involve an extension or new line and I spoke with Trevor. I have spoken with him a few times before and I just want say that Trevor is consistently helpful, extremely polite and kind. He is really personable and caring and I appreciate that he goes the extra mile to get the answers to any questions I have had. read more

The sole source of heat went out in an apartment in my building in Laconner Wa just before Christmas! Thank goodness for Clint DeFries from Foss Heating able to come immediately to provide an estimate for a replacement. Clint was very professional and I am pleased with his service. It's a mini split which is very efficient provides heat and air conditioning for the apt. The tenant is so happy and so am I as Landlord. The price was very fair for the value. read more

Foss Heating & Cooling - Laconner - Heating & Air Conditioning/HVAC Near Me - Mount Vernon, Washington

Our furnace quit working during the winter freeze we had in December of 2022. I called the heating company who installed the furnace first, only to be put on their "emergency list" and I never heard from them again. Foss Heating and Cooling came recommended by my neighbor so I called them next, and I'm so glad I did. They booked me for the first service the next morning and the service technician showed up right on time, and had my furnace up and running in less than a half hour. Now that is service! You can bet who I'll be calling first the next time I need my furnace or air conditioning worked on. Thank you Foss Heating And Cooing, we really appreciated your prompt and professional service. From my first phone call, to when the technician departed from my home, we received outstanding five star service and nothing less. read more

After a large tree fell on my heat pump, crushing it, my prior service provider told me it could take up to 3 or 4 weeks to replace (I had no heat). Foss came out within 2 days and installed it 2 days after that. They also determined that my old system was installed incorrectly and had incompatible parts. With the new system my house is warmer than it's been in years. Super happy with their advice and service. read more

Besides being expensive to have the mini-split cleaned by Foss, the 'help' you get as a customer is lacking. When there is a problem they seem to fob you off to 'look it up online'. They can't even answer any question that might explain what is happening in order to make a decision whether I have done something incorrect in the programming or if i need someone to come out. Big difference, and if they can't even ask a few questions to figure that out i call that BAD AFTER CARE SERVICE. It feels as if i am flying solo and they couldn't care less. read more

Andre from Foss Heating and Cooling arrived today as expected in their four hour window. He called to let me know he was on his way. He introduced himself and immediately addressed the services I requested. He checked out my fireplace and I also requested to get an estimate for installation of gas pipeline for a dryer. He quoted a very reasonable price and to my surprise did the installation today. He called in for some supplies which someone else from Foss delivered quickly so that Andre could begin working. He was very courteous, professional and got the job done in great timing. I would use them again and highly recommend Foss Heating & Cooling. Thank you Andre and Foss Heating and Cooling! read more

We are over the moon with the wonderful service we received from Foss Heating and Cooling today. I was able to secure an appointment the very next day after I called initially and the communication was flawless every step of the way. Every contact we encountered from our scheduler to our serviceman was friendly and knowledgeable. We wouldn't go with any other hvac company and would strongly recommend Foss for all your heating and cooling needs. Thanks again! read more

No consideration for costumers time! I told them I'd be traveling over 60 miles (with 2 children) for the appointment and the best they could give me was a four hour window of which they couldn't even make it to. Extremely disappointed. Update: the technician was very kind and considerate and got the job done as efficiently as he could. I'll change my 1 to 3 stars. read more

Found our condensation pump was broke and had water leaking out onto the floor. Called Foss first thing, texted over some pics, and they came out the same day. Brett not only fixed the pump, but suggested we service it. It looks brand-new again. Brett was very professional and courteous something I haven't seen in a service person in a long time. Thank you Brett read more

Quick service and very friendly, initially I would have given them 5 stars. The technician told me he would include information in order to check warrant status but he did not and quoted me $700 for repair. I was able to readily find the part online for less than $100 and finally sourced it for $56. Six screws and two pipes. $700, really??? Took me about half an hour. read more

parents a bad experience with Handy Heating trying to get a new water heater tank. So they decided to use FOSS. It was easy to set up an appt. the technician was professional and very informative regarding the new regulation on a new water heater tank. He assessed the situation and was able to provide a formal quote before leaving. The work was completed promptly and my parents are happy. Highly recommend!!!!! read more

I needed someone to install gas lines in an existing house, a gas stove, an on demand gas water heater, gas stove connection, a bbq connection and coordinate with the gas company. FOSS came out and crawled through my entire house including the crawl space to figure out the best way to install everything. The bid was competitive with other bids but I chose FOSS because they seemed to be the most thorough. The owner came out to evaluate the installation and to assure it was completed in the best manner possible. It all turned out better than I expected. I will be using them for my system and heat pump maintenance. I highly recommend FOSS for any heating or cooling installation or maintenance. Very Professional. read more

Normally I try and make these funny but this was just not a good experience. We had just moved into a new house and neither of the two gas stoves are working. They're the primary heat for the house so we were using the electric back up. Not a desirable situation but not an emergency. I was working so my wife met with the repair man. $240 to inspect and diagnose both stoves. We were told that one was unsafe to operate because of the monoxide levels and the other was out of production but needed a new temp probe, it was faulty and causing the unit to think it overheated. We took their word, they were genuinely nice guys. They sent a consultant a week later to-give us our options. $14,000 to have new stoves installed or closer to $20,000 for a ductless HVAC system. We ended up calling a family friend to give us some advice and what he thought. The one with the temp probe issue, it was that the pervious owner had the fan taken out for some reason and a $50 fan and a half hour and it was back to functional. The unit really was over heating. The second one, with out he pilot light on and being a cold day the cold air was forming a plug keeping the exhaust gasses from escaping and being pushed into the room. They tried to sell us a lot of product and charged us to be lied to. I don't appreciate it, I would only let them work on products that they had installed. read more

I got their service on heat pump on Feb 28th, 2019. While clumsy technician were staying for 2 and half hours, he had not done any cleaning. Most other technicians are doing some cleaning of filters. He removed some ice and then heat pump started working. He tested defroster sensor and one connector. I got shocked to see his estimate after he gave recommendation of changing those two simple gadget. The part cost will be less than 100$(maybe around 50) and it will take around one hour to finish it. But he quoted 750$. Also in addition to diagnostic fee of 150$, he charged trucking fee of 50$ more. I should not have paid 50$ more but I wanted that clumsy and lazy guy go away as soon as possible. Stay away from this terrible company,. It would be waste of your time and money. read more

I love this company! Any time I have a problem with my furnace or air conditioning I call Foss Heating and cooling. They are professional, fast and nice. I have them service my heater and air conditional every year ensuring I have no problems. Before I found this wonderful company, I had used another company that I was very unhappy with. I called Foss, they came right out and fixed the original problem and the problem the other company made. I believe that once you have found the best no-one else will do, I know I won't use anyone else. Please never go out of business. read more

Foss had their hands full with our antiquated heating system. Our service tech,Brett, was amazing...he truly cared about our problem and bandaged it the best he could. We are in the market for a new furnace, they are the first on our list for an estimate. Highly recommend this company! read more

They are honest and extremely competent. Have done business with Foss since 2008. They originally corrected a major problem the contractor who installed the heating system in our new home. We have used Foss since then and would not consider changing. They are simply the best! read more

Great company they keep promises. Basically no many big heating and repair company is not around Of this area . We followed reputation and had few times visit because heater is old and hard to fix but guy from there " Sam"? Fixed well for now. Talk to owner found out he is nice guy and I was misunderstand about something. Sorry for that. But emmet need help new heater next time anything happens we sure ask them to set up new heater. read more

My husband got these people to come out to install a new branch on a propane line from our furnace to our dryer. When I heard about a 100.00 charge just to bid a job I was worried they were greedy. We are moving the a new house and since things were getting complicated and pricey we did not have the energy to get a second bid (and didn't want to waste that 100.00)... The worker came out and bid the job, and my husband agreed. Unfortunately it cost over 1000.00 and this job should have been hundreds less. I realize he could have said nope to the bid but when you are already in for 100.00 and sort of over a barrel for time it feels very much like a huge rip off. After I saw the bill, I called some other plumbers with a description of the job, and they felt half that would be about normal for the length of pipe run, and to find out if there were some extenuating circumstances. Called Foss to complain and they just blew us off. The guy who called me to "explain" the bill said the worker had 4 hours work into the job... but that includes all their travel (I figure the 99.00 "bid" fee should have covered that; probably 45 minutes total travel. They arrived around 8:30 am and I had a copy of the invoice by 12:15...that was after the person left and had been paid, and my husband forwarded a copy to me. The only difficult part of the job was doing a crawl space.. isn't that pretty much expected? Of all the tradespeople and businesses we are using to get our new house together, this one stands out as the worst in attitude and price. They made out like bandits on us. read more

Melody was very unprofessional and rude on the phone. I won't be calling back for that reason alone.

A family member recommended Foss Heating. I first spoke with Kendra, then Trevor in service, they were both so friendly and professional, a pleasure to deal with. Brett, the technician came out and repaired and or serviced two gas fireplaces and our furnace. He was extremely knowledgeable and patiently answered all my questions. Everything is working beautifully. Im very pleased with my experience with Foss, and would highly recommend them . read more

I called to get a quote on a heat pump and the receptionist told me that they don't service my area. Then I looked on their website which illustrated that they do service not only my area but areas far beyond where I live. I called back and she told me in a rude and short way that they don't service my area, then hung up on me. I guess one of their competitors will get my $10,000. read more

Very, very. very pleased with the whole experience with FOSS. Everyone provide high standard of work. Estimate, installation, financial department - everybody who works there is professional, and i just wish every other company can provide same customer support and services. Installed with them a new center system AC for an office building in Mt Vernon. read more

These folks are professional and good at what they do. I had them replace my furnace with a high efficiency Trane unit and it has been great. The following year I had them replace my water heater with a tankless unit. Very nice installation and has been operating without issue for several years. Furnace failed this morning and Foss is unwilling to service unit because I live 10 miles south of their southernmost boundary for service calls. I understand that they are a business and need to keep their crews generating revenue and not on the road, but I feel a bit "stung" on this one. If they changed their service boundary, it would have been nice to have been grandfathered in given the substantial investment I've made with them. If I have been south of their service area all along, I could have gone with a different company for the installs. Either way, I'm now working with someone else out of necessity. read more

In the latest wind storm our power was knocked out and stayed out for over 36 hours. When it finally came back on we noticed our furnace was only blowing cold air. We called around and everywhere couldn't get to us earlier then that fri. (7 days after the power was originally lost.) We called FOSS they came out that night, within a few hours...The tech (Sam) was very knowledgeable. He was very sensitive to the surroundings aka appliances in the area of the breaker box. He explained the whole problem & solution thoroughly. If we ever have another heating issue we wouldn't call anyone else but FOSS. Thanks so much! A special thanks to Sam! read more

We had Foss give us a proposal for a new heat pump system. We were pleased that there was not the hard sell we encountered from one of their competitors. They gave us four options with all the information we needed to select the system that was best fir us. The costs were well documented and easy to understand. Everyone we worked with through the completion of the system has been very professional and helpful. We are very happy with the system and had Foss make repairs to the HVAC system on a second house we were selling. read more
