HVAC1 was absolutely amazing! We have had problems with our Mitsubishi Mini Splits ever since they were installed and multiple hvac companies came out and gave us crazy high bids saying we needed to redo the entire system basically (including ripping through most of our walls and ceilings). However HVAC1 came out and actually diagnosed the problem and found it was a faulty connection in the refrigerant lines. They came and replaced the connections (the correct way) and were extremely affordable! We now have had working heating and AC for the last 2 months and no problems!!! Thanks so much!
Prompt and excellent service! Highly recommend HVAC1
Vitale inspected and cleaned burner parts on 2 gas fireplaces on 10-1-22. He also replaced wall switch that operates upstairs fireplace. Very professional and knowledgeable!
The person who answered the phone when I first called having issues was extremely helpful in figuring out if the Nest thermostat was the issue. Then when it came down to needing a Tech. They were reasonable with scheduling, and came back out a second time to fix the issue after it was clear the initial problem wasn’t the only one. Tech was friendly and helpful with answering any questions and dealing with my kids and dog. I’d highly recommend them to anyone in the Spokane area.
When I was looking for service for my gas fireplace (and finding nobody available) I got in contact with HVAC1 and they were able to schedule someone to look at this within a couple of days. He came out, diagnosed and worked on the issue and had it running quickly. When I called later to ask some further questions he eased my concerns totally. I highly recommend this firm for any and all repair work--very professional and quick to respond.
Very happy with the level of service provided by HVAC1. I previously had a different company from the area come out and assess my furnace. They told me the motor needed to be replaced and that I would need to pay $1500 to do so. The tech from HVAC1 took apart the motor and found out it didn't actually need to be replaced, and instead only needed to be cleaned out! Thanks to him, I saved a ton of money! If you need work on your furnace, or need a second opinion after getting an outrageous quote from another HVAC company, I 100% recommend HVAC1.
The Best service ever! He came when you said he would. The young man was polite friendly and got the job done. So happy I found you. Thank you. Nancy Shively
We initially contacted HVAC1 when our previous provider's technician quit and was unable to provide service. HVAC1 was recommended by a friend. In conversation with Marissa at HVAC1, we were able to solve our cooling issue without having a technician visit. When time came, we called HVAC1 to provide annual heater maintenance. A technician came out next day. Now we are all set for the upcoming season. Any team members we have spoken with are knowledgeable and helpful. We will continue using HVAC1 to provide our maintenance services.
They are simply the best! They are Honest! They are a source of experience and knowledge! Reliable and effective! 100% recommended
I couldn't be happier with how quickly they were able to come out and replace our old AC unit during this heat! The technician was very nice and efficient with his work. I will highly recommend the company to everyone I know in Spokane ! thank you again for all you do!
We asked Hvac-1 to check out our central air conditioner. Paul the owner sent out one of his very best technicians Vitality Kir who was able to diagnose the problems and remedy it. We have come to be able to depend on Paul and the confidence of his crew every time we call them.
Did a great and efficient job at putting in a full new ducted system in our house. Trustworthy and beat their competitors nicely.
HVAC1. Mike installed my new furnace. The one removed was pretty old. He & (Tony, up on roof sealing off old vent) worked hard. Am also Impressed with office staff. Marissa you awsome. The owners run a professional business. Thank you all for being there for me & my home.
So glad I went with this team. 😀

Called two other companies to have them check our boiler and the first company was very rude and tried to over charge us and the second company didn’t even call us back to let us know if the boiler was okay. Called this company and they came in and fixed the valves at a much lower price then the first company. Great communication with the tech and the front office. Highly recommend!!
Great repair gentleman. Very polite and helpful. I will use these folks again.
Great service! Furnace was fixed and Vitaliy was awesome. Thank you!
They were great came fast and fixed my heater. Wonderful people
Excellent service. Called and repaired in less than 24 hrs.
I cannot praise them enough! Our A/C went out on the 4th of July. HVAC1 was the only company who could get us in the same week. Their customer service individual was personable and very communicative. I really enjoyed communicating her about the woes of no A/C. She also ensured we were in the loop about everything and was great with followup. Vitaly was our serviceperson and he was fast, efficient and knowledgeable. He came out 7/9 and diagnosed the issue within minutes and had the broken parts out of the A/C. He was back the following Monday 7/12 with the replacement parts and the A/C fixed with inordinate speed and care. I just cant praise these guys enough! I am so happy we hired them. The price was extremely reasonable too!
this is a great team. Paul was quick to find out the very best product for our house. He noted that the system we were replacing was a 100k BTU system but was only 85% efficient. By providing an 80k BTU at 95% efficiency he was able to provide the same capabilities to our home and save us money. 5 stars well earned.
Installed mini-splits in the lower level of our home as well as additional duct work to our existing furnace system. Paul and his team are professional, trustworthy, and experts in their industry. Our project was completed on time as promised. The appliances and craftsmanship are of superior quality. We are very pleased with our new climate-controlled environment and the working relationship that developed between Paul, each installer and the company! We highly recommend HVAC1 (Semenik HVAC)! Thank you for a job well-done. We wish you and your company much success! (residential, Spokane, WA)
All I can say is that Paul and his employees are truly amazing! Great service, they went ABOVE and BEYOND to get my furnace working for me, professional, friendly and kind. I cannot thank them enough!
Great price, fast, no BS and very clean install, like they were never there.
We were very impressed with the service we received from the technicians at HVAC1. We were able to get an appointment within a day of calling. The technicians were friendly and their service was top-notch. We were pleasantly surprised by the affordable price as well. We highly recommend this company!
Great service. Tech was very knowledgeable and gave me some great advice on what to keep an eye on. Also solved the leak in our system. Definitely recommend and will use HVAC1 again. Thank you!

I am very happy with your service, excellent and fast cleaning my system. Your technician is courteous and efficient. Thanks again!


HVAC was fast efficient and reasonable. I was delighted with the work they did. My tenants are happy too.


We have so pleased with this company, since they were recommended to us. They are always on time, know exactly what the problem is and fix it. There tech is very well qualified, on time, friendly, does his job and leaves. I would highly recommend this company to anyone, which I already have.


HVAC1 did a fantastic job all the way around, from making the appointment to finishing the job. The technician, Vitaliy was so professional and went above and beyond for us. He made sure everything was working well and found a leak that we did not know about. He cleaned the area extra well and it looks great. We could not have asked for anything more. Excellent service and experience.


We are very pleased with the service we had today. Both of these young men worked very hard to get the job done. Thank you to you all. Especially Michael and David!! Great company to work with!


They did the tankless water heater install last year and we had a service call yesterday I am very pleased with HVAC1. Service is exceptional. The technicians do excellent work and are very thorough in explaining what they’re going to do. Keep up the good work.

This was the 3rd time I have utilized HVAC1 services. And, always when it's an emergency. Very responsive. I really appreciated Vitally coming late on a Friday afternoon. More importantly, he explains what he is doing. Thank you so much!
