Do not use this company unless you want to pay double and sold on products you don't need! My fireplace pilot would not light. Tech came out and said I needed a new gas valve and I should also replace the pilot ignitor at the same time, even though it wasn't faulty. I stupidly didn't research the reviews of this company and said yes to a $1700 quote! Found out later that was at least double what others charge. Turns out we got the pilot lit on our own and I wanted a refund on the pre-paid parts (minus return shipping), since the fireplace was now working. Owner wouldn't work with me and got so angry and called me swearing and called me a Karen on the text thread! He was SO unprofessional that I just went ahead and disputed my credit card charge. read more

Have dealt with many HVAC companies in the valley and this is far and away the worst. Horrible service and hostile owner.

Stay away from this company. Unless you want to pay considerable markup for parts that don't need to be replaced. Oh, and if you bring your concerns to the owner, be prepared to be yelled at, cussed at, and demeaned. read more

Fast, friendly service! My fireplace needed a new insert and Quantum was able to install the new one and it is just wonderful. They left my living room spotless! read more

Great company from the person who answers the phone to the repair people. The customer service and scheduling the appointment was awesome, thanks to Selina. Beau was our service person he did an outstanding job. Very professional and friendly after the job was finished he cleaned up and vacuumed the area. Would hire this group again. They came to fix a freestanding fireplace. October 13, 2025 read more

Had a disappointing interaction while inquiring about fireplace fan repair. When I asked basic questions about service costs, I was met with defensive responses and told they're 'only interested in customers who want to pay.' Their $195 diagnostic fee was only revealed after multiple requests, and came with condescending remarks about 'hiring professionals.' Instead of simply stating their rates upfront, they seemed more interested in lecturing potential customers. While they may be skilled technicians, their customer service and communication approach needs significant improvement. The passive-aggressive responses and reluctance to provide basic pricing information made me glad I hadn't scheduled service with them. Would not recommend based on this interaction alone. read more

Owner rude and totally unprofessional. When my wife called with a concern after an installation, all he could respond with was to belittle and act immature. Then totally took no responsibility for his responses. There too many other competent hvac companies. I would not recommend this company read more

Save yourself time and money and find another place. Josh had his workers come on Friday, they didn't complete the job and scheduled a follow up for the next day (Saturday) at 2pm. My wife called at 3pm to see what was going on and had the pleasure of speaking with Josh, the owner. She asked about the bill from the day before where we were charged 12% tax when our local area has 7.25% tax. This set Josh off. He lashed out and verbally abused my wife. He called her horrific names, made sexual references to her and what acts she should do. When I stepped in he called me every derogatory word he could think of as he threw this toddler like tantrum. He called me a homosexual and told me multiple times to go back to my own county (I'm Australian). He threatened us. He called us back three times to hurl additional insults without letting us say a word. We needed to file a case with the local police department due to his threats and harassment, we have since reported him to the BBB, the Consumer Protection Department, and the fraud division of the Utah state tax authority. This man has serious anger issues. No customer deserves to be abused as we were. If you have witnessed his abuse then report him to the resources above. Abuse is not ok. Insulting women is not ok. Being racist and a bigot is not ok. Check the invoice out below and do your own math to see Josh is ripping you off with taxes so high they are not even seen in California or New York. State taxes are not 12% in Utah and don't let yourself get scammed by this vile individual. Edit: Utah State Tax Commission Publication 42 Rev. 6/23 actually says that the type of service we were charged for is non taxable in Utah. Charges for cleaning real property (i.e. furnaces, built in HVAC, fireplaces) is non taxable. So not only is 12% wrong, even the 7.25% would be illegal. Edit #2: I also am including a response from the Utah Tax Authority. The cleaning should have 0% tax read more

My wife and I couldn't be happier with Quantum Heating and Cooling. Yesterday began with our AC unit that was not working. My wife called another company but they said it would be 2 weeks out. I recalled that we'd used Quantum before so she called them at about 9:30 or so. It was scheduled for a repairman to come out at 3:00 PM THIS SAME DAY. Joshua came to our home with American made parts and replaced the faulty parts and had us up and running by 3:30. He was extremely courteous and careful about wearing shoe protection whenever he came in the home. We are pleased with their service...especially Joshua. read more

They came out to service our fireplace. Told us we needed a new part and were going to charge us almost $1200 for everything. We hired Loves Fireplace and they came out and cleaned, painted and serviced it for only $225. Said no parts necessary and guaranteed the work for a year. I love Loves and these guys are a scammer!! read more

Run! The owner is very scary, although the workers he sent were very nice and gave me a bill verbally they could not send a quote number with their recommendations. They would not put the bid in writing. I was not told in advance they did not put anything in writing and I expressed I needed this for a court case. When I called and asked for a memo bid on what they told me verbally, the owner started yelling at me and said they don't do that it costs too much. You get nothing for the $150 service call, then he threatened to call the police because I complained that I should at least get a bid paper that stated what they saw as all other businesses do. Then he sent me unhinged text messages. The only good reviews are probably made up by their relatives. Please see the BBB.org - Better Business in Utah for additional information on this business as it is "not BBB Accredited" https://www.bbb.org/us/ut/stansbury-park/profile/building-contractors/quantum-heating-and-cooling-llc-1166-90025327/complaints. and I am also unable to find a contractor license on the division of Professional Licensing: https://dopl.utah.gov/ read more

465.00 for the part and charged almost 500.00 for labor, which took 43 mins. The tech told me they charge 218 per hour of a minimum of 2 hours, plus there is a 30 dollar fee for them to pick up the part at the supply house. Will not use again and will NOT refer to friend or family. greedy people read more

We called Quantum for chimney cleaning of our wood stove. They did do a comparable job, but they charged extra for everything: 1. $300 just for the drive to our address on the East side of SLC (they are based in Herriman). 2. They wanted to extra charge just for cleaning the stove itself....Huh??? We cleaned the glass ourselves. We were planning on calling them for an annual visit, but it is the most expensive Chimney cleaning call EVER? So, unfortunately for them, they will miss out on any future business from us. read more

Horrible experience. Our gas fireplace started going out so we called them. Josh came out and said we needed a replacement part and that we'd need to pay for the part upfront and then when they received the part it would be an additional cost of labor. We paid over $400 for the part. Two polite guys came and installed it and started doing some other cleaning and maintenance. One of the guys doing the work said the additional cleaning was normally $360 but because we ordered a part, it was free. Half way through he said it wasn't free because the part wasn't big enough?? So I told him not to do it. They finished up and had the fireplace working. And then he gave me the total labor, and cleaning ($360). I reminded him that I had said not to do the additional cleaning? I didn't schedule that. So he lowered the cleaning price to $260. I agreed to pay the lower price because he had done the work and he was a nice kid. The total was $460 for cleaning and labor. We paid it. They left. After they left, I googled the part that they showed me they had to replace. It's $45 for the exact one on Amazon that they charged us over $400 for. Now, maybe there is something I don't understand... Maybe the exact same looking part on Amazon for 45 dollars is a cheap knock off that shouldn't be purchased? I'm a reasonable person. I thought I'd call and talk to the owner to have him explain the high cost. So I called to try and see what the reasoning was. I was not rude or aggressive. I even complimented his employees on being polite. Before I could even finish explaining he started getting worked up and cutting me off telling me that he quoted us for the cleaning and that I had just been out of the room. To be clear, he did not. He started using profanity, yelling and telling me I was harassing him???? He wouldn't even let me talk. I mean, totally an insane way to responde to a customer with a concern. I hung up on him and he started texting me telling me never call him again or he will file charges for harassment! His name was Josh. We just paid him over 900 dollars for, from what I can tell was a $100 job and then got his wonderful customer service. Don't worry, I won't be calling again. Update : I posted this review on Google and when the owner saw it he began harassing me through text. Using profanity, calling me names, calling my husband names. He has since removed my review and one other 1 star review from Google. read more

A technician came out to service my gas fireplace, was here for less than five minutes. Told me the fireplace was old, and needed a $900 pilot assembly. Later I found that the gas was not on when technician tried to light fireplace. So I called Quantum HVAC back, asked them to explain how to light a gas fireplace with out the gas being on. I was called a bunch of witches and several F bombs were dropped. This is the most unprofessional business I have ever dealt with, secondly I think it is a scam. They take advantage of senior citizens. I would not recommend them to my worst enemy. 2 weeks later I am still traumatized by the phone call I had with the office manger. read more

We had Quantum come out recently for Fireplace repair. Our gas fireplace was turning itself off after being on only 5 to 15 minutes. The young man who showed up seemed very affable but didn't spend very long examining the fireplace. He explained that the problem would be solved by buying 2 parts and with labor the price for fixing it would be over 1500.00. We had similar problems before with a different fireplace and it had been fixed for a far cheaper price so I told the employee I would check around and price the parts he said we needed and then call again. I am SO glad we didn't go with Quantum. Fireplace etc came out a few weeks later and told us the problem was a dirty sensor. They cleaned it and it works great. The cost was $185.00 compared to the 1500.00 Quantum quoted. Quantum is either totally incompetent or just out to fleece customers. Stay far away from this business. read more

Had to reach out to Josh and his team 7+ times to get updates on a part that was ordered AND PAID FOR. He was not proactive at all and seemed agitated when I reached out for an update. He was sarcastic and rude on multiple occasions. This was a 4-month process on a simple installation. I will not be using his services again. read more

My experience was great. Had Cody and crew come out to fix my gas fireplace (which wasn't installed properly by the first company). They fixed it, followed-up quickly, were on time/early for their appointments, were very professional and did a great job. Also, Selina with the main office was very responsive with communication and updates. Highly recommend these folks. read more

I am 77 years old and i had The Quantum Company come and start my swamp cooler for the summer. This people came worked for less than half hour charged me $174.99 when they had quoted $129.00. Less than half hour after they left the cooler stopped working! I had my son called and he gave him a laundry list of what else was wrong with the cooler TOTALING 1000 DOLLARS. The list came after the fact, after they had left and got paid! My son spent 2 hours and $42 to get it working. $174.99 to turn water on basically. I ADVISE PEOPLE NOT TO USE THIS COMPANY! THE LACK INTERGRITY AND HONESTY... read more

They did not completes work. Work they did was substandard. I'm handicapped so couldn't go on roof to check it. Found out when the roofers mentioned continuing issues. It was a mistake to pay them but they said job was completed...I've waited for 6 months with constant promises to return to fix job. I'm finding another contractor and taking QUANTUM HVAC to small claims court. Avoid!! read more

This is by far the worst business that we have ever dealt with. Shoddy workmanship, you can't believe a thing Joshua tells you, he has never finished our job but has told us numerous times that he is "going to". You see the photos he posted about our job...well the empty boxes and the pallets were just left in our driveway along with our old water heater for us to get rid of. You see the water heater pictures well our pictures are the way he left it. There are NO safety restraints and there are supposed to be two of them nor is there an expansion tank which attached. These are all code by the way. Look at the pipes coming from our water heater and how they are tied up with our own coax cable. Stuff is just hanging everywhere Shoddy workmanship The two large white pipes that are connected to our new furnace are the new ones that we had to have another HVAC company install because of the way Joshua left it because first our furnace did not work properly and secondly because it flooded our basement 2 times within a month. That also cost us an additional $1700 We also tried to find his HVAC or Contractors License but we couldn't find one on file with the State. We tried Joshua Steven Gardner, Quantum Heating and Air Conditioner and nothing. We which we would have looked first not after so, BUYER BEWARE OF THIS COMPANY! read more

I have an HVAC cooling issue issue, I called Friday afternoon and they were there within an hour, which was incredible, I should've known it was too good to be true. Technician Joshua G. Showed up and was polite, I have a young child that wasn't able to sleep well because of the heat. After service I paid $340 for nothing and was told my control board was bad and got quoted $1200, I asked for a parts list and got nothing and was told "it will be on your file when you're ready to repair the unit". I work in the commercial field and have worked with a lot of different HVAC companies over the last 15 years and after this terrible experience, I called one of my contacts and after an 11 minute phone call, we got the unit running and it was a wire that was crossed, I called this company as this was a personal home issue, so beware of this company as they do not seem to be practicing ethical business practices, I've already told many of my friends and I will let all of my commercial contacts know to never use this company as they do not provide ethical business. read more

Don't walk away from Josh, RUN!!! He will make your home project, and life for that matter, a living hell! We hired Josh and his "crew" (which you should know is only his younger brother and Dad) to finish our basement. We fired him 1 and half weeks into the project based on really crappy work and ridiculous up charges for things. He way oversold his abilities to do quality work. I have attached a bunch of pictures so you can see just how shoddy his work is. In the past couple of weeks, we've since had multiple plumbers, HVAC, electricians, and framers in to give us bids on cleaning up his mess, and all of them have commented on how bad the craftsmanship is, and they feel terrible that we got hosed as bad as we did. One of them even asked if he could take pictures of the plumbing so he could show his crew how not to do things. We paid Josh $13,000 for terrible work that is going to have to be ripped out and redone. Josh acknowledged that we overpaid him by about $4,000, but he insisted he wasn't giving us any money back. He touts himself as an honest business man who will give his customers a fair pricenothing could be further from the truth. An honest person would have only accepted and kept the money he'd earned for the work he did. We pre-paid him and he threatened to lie to the police and say that we were holding his tools hostage, and he would push for a lien on our property until we gave them back. Again, nothing could have been further from the truth. I had to beg Josh to come get his tools out of my basement, so I could move on with others who are legit, professional tradesmen. Josh tried to upcharge us $236 for each canned light we wanted to add to our basement project--most other electricians would charge $50 - $80 per light on a project they were already engaged on. In addition, the plumbing work he did was atrocious! He wasn't willing to jack hammer through our footing to get the drain for the washer/dryer hookups in the wall, so he left us with pipes that are about 8 inches away from where the wall will be framed (see attached photo.) Based on expert opinions from two other plumbers, we're pretty sure he didn't put p-traps on the drains either--which means we would have had a stench in the basement if we didn't get a true professional in to fix it. He ran 4-inch drains into 3-inch drains which is against code. The HVAC (his specialty) needs to be moved or completely redone in some parts. The framing work is literally laughable (see attached pics.) His brother can't hit a nail in straight, so he just used 5 nails when 1 would do the job. He added these weird braces throughout the framing and the corners are left with hanging boards that aren't attached to anything (see attached pics.) The electrical work is all wired on one continuous loop, for a 1,225 square foot basement. We have literally been told that he shouldn't be in business by 4 different tradesmen. We're not vindictive people. We just don't want anyone else to get scammed like we did. Hire Josh and his "crew" at your own risk. You've been warned. read more

Horrible company to have your central air done with. It's been about 8 months of trying to get ahold of them since they have installed our main stuff but they still have not came to install the thermostat or add another vent like we agreed. They dont give you any updates and if you call to find out you dont get anywhere and when you finally can get ahold of them you get yelled at for wondering what is going on. They do not care about their customers one bit. They took the money we paid them and said they would be in touch but have not reached put one time. They came and said they needed their payment and would be back but have been ghosts since. Just a really horrible company with bad work ethic and even more horrible customer service. read more

Had them come out and replace a water heater. Was told the water heater they were installing had 500 dollar rebate so we decide to use them. After installation we called multiply times to get an invoice. It's been a month and still no invoice and rebate program is no longer excepting applications. Talked with the main person and all he could say on the pone was oh call this number and gives me a number that does not work. I would never recommend any one to use them unless you want to be lied to and get the run around. read more

Had these guys install a new furnace and AC for us very fair priced great work friendly what more can you ask for !

Josh and his company have fixed multiple heating furnace problems and water tank issues multiple times in our rentals. When we have a problem we call him for fast fair service. We have been very happy with his work. read more
