I have used Mountainside Air as my go to for HVAC inspections every year since the purchase of my home in 2021. I had them out Friday 3/14 to perform the annual inspection and the tech found no major issues. I woke up 4 days later to a hot home with no AC. Imagining the worst, I called Mountainside Air and explained…

Very informative and pleasant technician who explained everything in detail. Will definitely use again.
Mountainside is the BEST. They were super quick to come out and figure out what the problem was, the tech was very nice and informative. Best service!

My home warranty company was being difficult and I needed someone to come out sooner than they could/would accommodate. Actually asked ChatGPT to recommend a reasonable and reputable company near me and Mountainside was at the top of the list. And now I know why. When I called I spoke with Kate, who was…

He was professional, knowledgeable, and genuinely…
I noticed that my A/C wasn't cooling so I called Mountainside Air. It was around 7:30pm. Josh arrived not long after, and by 9:30pm my A/C was working again! I've had Mountainside out a few times, these guys never let me down! Thanks for the great service.
I called in a few weeks back with an issue, they could not get a tech out but offered mesome advice and got my AC working. I decided then they would be my new service provider. Had another issue today, tech was out in a matter of hours, very friendly guy. Very happy with the service provided.
Fast response, quick repair.
Last minute call for an issue. Steve had a technician in the area. After finishing that job came right over to my place to evaluate problem. Found problem confirmed with me for approval and installed new parts needed. Everything good Thanks
Repeat customer and once again they didn’t disappoint. Worked around my schedule to come out same day to get my AC running again. They also arrived at the beginning of my time slot so there was no waiting for hours in the heat. Thank you!
Mountainside Air was very responsive. The technician Victor identified and repaired the problem quickly and efficiently. Very good experience
Scheduled a checkup and they were able to catch catch something before it got worse. Great service. The technician kept me updated the entire time.

This is the second time I have used Mountainside Air. They are reliable, arrive on time, communicate problem, fix right away, and their prices are reasonable. I will continue to use them when needed and recommend them
We love Mountainside Air! Been using them for 6 years. We messed up and called another company one time and they said we needed $2400 worth of work and we said we will get back to you and called Mountainside and they came out and said our AC was fine!!! So don’t get scammed! Call Mountainside Air! Friendly…
I cannot say enough about Montainside Air. Same day service and very reasonable rates. I will not change AC companies again. Tom and Steve very knowledgeable and professional. Updated: New AC system installed, and works like a dream and really cut my electric bill. Update: Condensate clogged up and again…

Great Company and Cristian was very professional
Our air conditioner in the primary bedroom quit working late yesterday afternoon. I called Mountainside Air and they immediately responded back. They provided me with a workaround. The following morning Steve arrived and found several vents which were closed and opened each. He also changed the filter. The air…
It seems as if your people are knowlagable and are out to do things right. I appreciate that. Thank you.
The crew was nice and very professional did everything we wanted and worked hard. Raul is very talented at his job he made things happen. Thank you Mountainside Air.
Second time I have used Mountainside Air and am not disappointed. Fast friendly and knowledgeable.
Chris was outstanding and very helpful to us, our dog likes him too! Good job thank you
Had a bad blower motor replaced by Cristian. He did a great job. Answered all my questions. I will set up my checkups with Mountainside Air. If I or any of my friends need a new AC unit I will definitely recommend this company.
The team was prompt on time for the appointment. They made sure everything was secured and cleaned up when they left. Great service by the whole team!
Workman worked very hard to try to fix my A/C system, but it was not repairable. TYVM for trying!!
I have had 2 techs for different jobs and they both were excellent. Installed thermostat where Threshold said couldn't be done.
Love this company! They explain everything, reasonable pricing, great technicians! Highly recommend!!
My AC system blower had started short cycling. I was able to change out a few simple/cheap components that I know can cause this myself, but when it did not fix the issue I called Mountainside Air. This was my first time using Mountainside and I was very happy with the service. They sent someone out the same day and…
Very prompt and friendly service. Tech arrived as arranged. Diagnosed and fixed the a/c.
I woke up to an 82° house this morning. I made the perfect choice with Mountainside. Steve was my technician and he explained everything to me in a way that I could understand and was very honest.
Quick, knowledgeable, and reasonably priced!
Was very glad they showed up at 8 am and not noon. All issues explained well along with pricing. Repairs done in 2 hours which was awesome.
I chose Mountainside Air repair due to their five reviews. They came out and diagnosed the AC issues which were clogged drains in the attic, causing a leak in our family room. I am now going to use them for annual air conditioning check ups to prevent any mishaps in the future. Congratulations to Mountainside for…
Chris S was pretty amazing, although he couldn't help me, (I need a new unit), he delivered the bad news with grace, empathy, and a really pleasant demeanor. He was encouraging and is clearly an asset to this company.
The service man was prompt and diagnosed the problem in a few minutes. He made a recommendation for repair and suggested we think about replacing our 17-year-old old unit. The repair was done within an hour and cooling was restored.
My ac unit quit blowing cold so I googled for ac service in my area, found them, and saw all the awesome reviews. So I figured I’d give them a try. I filled out the contact us on their web page and I heard back in under 10 minutes, and got scheduled quickly… and also they were able to accommodate my schedule on a…
Christian was great! Was on time and completed all needed work. I would recommend this company to anyone.
quick response. got the job done and saved me from having to replace the whole unit. 5 stars.
Nice individual and knowledgeable.
Awesome awesome service!! My mother's a/c took a crash so I called Mountainside Air on a Sunday spoke to Steve, one of the owners, he told me they weren't available until Monday, but was more than willing to help me over the phone being that the issues I described could be an easy fix. Unfortunately we did need…
Straightforward, honest and refreshingly professional service call. Steve was down to earth, he explained things from his perspective if this situation were to happen at his home. He Took care of our air conditioning issue on the spot and left me with a very comfortable piece of mind feeling that my Air conditioning system is now in very good hands
Tom came out on time, was very professional, knew his trade well, kept me informed every step of the way, invoiced me correctly and I am very impressed with all aspects of the AC repair that was under the other bids we received. Fantastic service!
Very responsive, even on Sunday. Prompt, professional, and economical. They take a personaI interest in solving any a/c issues. I will use Mountainside Air for all future HVAC needs. I highly recommend them.
Tom and Mountainside air installed my new AC unit. As a landlord I was in a time crunch to get a new unit in. I reached out to a few different companies. Mountainside won me over with every aspect of company. From the professional phone call in the beginning to the handshake after the installation. A few months…
Excellent company! Workers were on time, polite, professional and knowledgeable. Workmanship quality was excellent and the system as a whole was a great value! Highly recommend Mountainside Air…
Professional service. Replaced compressor.
Very satisfied on time excellent work and clean up.
Mountainside was fantastic to work with. We called on a Sunday morning, when it was 95F inside and they responded immediately. Due to the extreme heat wave they had to schedule us out one day, but they brought several portable AC units to keep the house livable. The owner, Tom was the one who took the call (again,…
Great service. Technician explained everything they saw, diagnosed and fixed. Gave good tips for how to maintain the unit. Friendly, effective and quick.
I called Mountainside Air at 1pm and they were able to send someone out so quickly to help fix our AC. The technician Josh was nice and professional. We will be using them again!
What an amazing experience! This will be my go to AC team without hesitation. Josh and his assistant came out to the house took time to assess the situation, and explain what was going on. They could have easily fixed what I was initially told by another AC company but Mountainside Air has integrity and didn’t do…
Very quick to fix your problem and work with you on a new unit. Very professional!
Great folks to work with, trustworthy, professional, knowledgeable,and very easy to talk to. Made my repair process easy and painless

Great experience. transparent, affordable, fast and a veteran business, what more can you ask for!?
My ac unit was performing poorly last Thursday . Wouldn't cool my house below 87 in the afternoon. I called Mountainside Air. They scheduled me for Friday afternoon between 12-4pm. The tech was here at 1230 pm. He did a thorough check and determined the problem. Had my unit up and running properly a few hours later.…
Mountainside Air were responsive when I called when my elderly father's ac stopped working. They responded within an hour and they were professional. I was impressed!
Very fast response and saved the day. Raul was AWSOME
Steve and Josh were awesome! They went right to it, located the problem with the AC unit. Up and running in 30 minutes. It was a 114 degrees, but they are some Cool Dudes!! 😆
They have provided nothing short of superior service to both my clients, and myself personally! They have always gone above and beyond expectations!
We have used Mountainside for years and will never use anyone else. They fixed our problem immediately, they are always responsive, quick to solution and a company you can truly count on!
2nd time using Mountainside Air, excellent customer service, takes time to communicate. Worked with Tom first time, Raul this time. Highly recommend.
Great service, very personal service technicians as well. Small shop with a great attitude and appears to care about its clients needs. Doesn’t try and upsell you on a new AC since the technicians are not commission based employees.
Mountainside Air has one hell of a team,, each and every employee I have worked with is hardworking honest and very communicative. If I had 4 hands I'd give them 4 thumbs up. Highly recommended 👍👍👍👍
From the initial visit to the full system replacement, the teams were professional and great to work with it. Steve and his team were at our house and ready for a full system install one day after our initial visit. The team did an amazing job and the entire process was seamless and easy. I highly recommend Mountain…
Very honest professionals. I have had them out two times to assess and different problems on an older AC system. They never try to upsell maintenance or unnecessary repairs. A very trustworthy company.
