Paid a premium for a new HVAC system, and the A/C has had issues every summer since installation. Service calls have been frequent but only resulted in temporary fixes. Most recently, the system failed completely, and despite promises of follow-up and support, the company has been unresponsive and disorganized. Communication is poor, and I've been left without A/C during extreme heat. Very disappointed in the lack of reliability and accountability. Would not recommend. read more

I'm going to be calling One Hour to send a technician over to review the reports I'm getting from other companies explaining that my ten year old Amana system is in need of replacing because it was not installed correctly to begin with. read more

Very satisfied with the work performed by Chandler. He was punctual, performed quality work on the installation and answered all of our questions. Very professional. read more

Here's the thing - we LOVED this company at first as their installation crew and sales rep were amazing. We spent a LOT of money to get a completely new HVAC system installed in our house after ours went out. The installation team was polite, professional and very respectful of our property. This is where the good ends. The Customer service from this company is awful - like non-existent and AWFUL! We called 4 times in 4 weeks to have the billing department send us our itemized billing statement to show what we paid for our furnace and new AC system and the cost of the install so we can send the information to Xcel and United Power for rebates we qualify for. EVERY time we call, we get a representative who says they will "put the information in the computer and have billing send us the info we requested." It has been over a month and still we have received nothing. I just called again and spoke to Edgar, who refused to transfer me to the billing department and said he had no manager available and had no other numbers but the customer service scheduling line, which is where he worked. COME ON! They designed a system to purposely eliminate any actual "customer service" and give me the run around. How long does it take to email me a detailed invoice of my purchase? I mean we certainly already got the bill for our 1st payment due, so why does the billing department need WEEKS to email what should be a simple invoice with purchase information? Very very very disappointed in this company. read more

Christopher is great. One Hour is lucky to have him on their team!Great communication and customer service. He quickly fixed the issue I was having with my humidifier. read more

DO NOT CALL THIS COMPANY. tech told me my 4 yr old furness was the cheapest available, that it looked 20 years old, no way to fix it, worst he'd seen in 29 yrs. Gave me the hard sell-a complete new system. I left the room for about 2 mins. When I got back he said he removed the flame sensor, cleaned it but it didn't help-$10-12k system Needed. HVAC friend came over. Said my furness and system were fine, cleaned the sensor, said it had NOT BEEN CLEANED. system runs great now. He said the Rhude furness' can last 20-30 yrs. Dishonest, out and out liar for a tech. I can't imagine how many people they have taken advantage of. The WORST kind of company, this is what is wrong with society-greed and dishonesty. BUT!...they were on time! read more

One Hour has always had technicians who explain everything clearly. If I say no to a service or recommendation, they respect that. I would recommend One Hour. read more

I don't know why I didn't look up the reviews for One Hour Heating & Air Conditioning of Loveland before I scheduled them. I agree, they are a 1 star company. I made an appointment with them over a week ago for our house in Boulder and was depending on them because I was only going to be in town for two days. I flew in late last night to be here first thing this morning for our appointment and one hour before showing up they call to reschedule. The person calling showed absolutely zero concern or regret even after I told her I was depending on them showing up. I was angry, but in reality, I am glad to know their busisness practices up front because was planning to spend a lot of money installing an entire new HVAC system so I definitely DODGED A BULLET on this one. THANK YOU 1 Hour!!! Hmmm maybe they named themselves "1 Hour" because they cancel 1 hour prior... read more

I've dealt with One Hour Heating and Air 3 times in the last 6 weeks. Yes, you read correctly, 3 times in 6 weeks. As a result, I have a very good understanding of how they work. Call 1. My AC went out, the repair tech came out with the $90 trip fee, said it was the capacitor, and replaced it. This fixed the problem. I then paid the additional fee for a complete diagnostic top to bottom, the one they recommend you do yearly, and the tech said everything checked out great. Despite the $400 fee, I was so happy and posted a 5-star review! Call 2. Now the problems start. Just 3 weeks after visit 1, the unit started leaking! I paid another trip fee of $90. Tech comes out and says the main drain line was plugged. Huh? The drain line suddenly plugs up 3 weeks after a supposedly complete diagnostic? I guess so. I paid another $300. (I can't help but think the tech inadvertently plugged something when out on visit 1, but I have no proof.) Call 3. Just 2 weeks after visit 2, the unit starts squeaking VERY loud, like there is lubricant missing or something like that. I call One Hour again (by now they are on my speed dial), and said, hey, "something is going on here, I think the the tech is missing something - can you come out without charging the $90 trip fee? I'm okay paying a repair fee for whatever it is, but 3 trips in 6 weeks seems out of line." Nope, they will not. They want the $90 trip fee on top of whatever repair. Even though I just paid the trip fee twice, likely for something the tech missed on visit 1! So I'm looking elsewhere. If I'm paying a $90 trip fee, it's going to somebody else, who will hopefully catch all problems in one trip, not three or four or six.... In short, my review is this: One Hour will nickel and dime you to death if they can. read more

Beware. Always get a 2nd (or 3rd) opinion. Don't rely on their 3 Option Close. "Why would you get other estimates? I'm giving you 3 right now..." is a ploy they teach. A sales pitch. This company is shady. And the ripping people off approach comes from the top down. I've met the owner, Cory (listed as the VP of Operations on their website, but he's the owner), and he's not a very pleasant man. Great salesman, horrible person. Doesn't care about you or what you really need. It's all about the $$$ for him. Believe the other negative reviews and find a more reputable company. read more

I had a great experience with this company in servicing my HVAC. They were available the same day and super helpful and informative. I felt their prices were fair too. I see some other reviews about selling you on things, but I did not have that experience with my technician Scott Callahan. He was honest about what needed to be done, and only recommended one fairly inexpensive part be replaced of the two systems he serviced. read more

I got a whole new furnace and AC put in through them in December of 2022 running around $20k with all these promises of "hassle free" maintenance and "no lemon" guarantees only to have the system break down TWICE in the two years since. First, the furnace wouldn't heat properly a mere 6 months after purchasing it and it took a tech 2 or 3 trips out to my house to repair it. Was the $500 awarded for their promise to come out with 24 hours and fix any issues under warranty? Nope. Then 6 months after that, my AC isn't cooling properly, a tech comes out and isn't able to finish the job AGAIN. I have two different techs come out that summer, one because a part of the AC unit wasn't working properly/leaking and thus was completely frozen over and another one to do a routine maintenance job on the AC unit. Neither tech did their jobs completely and the second one "didn't have enough fluid in my van to do the flush it needs because there are particulates in it. But dispatch will get someone out here soon to do it." Did this happen either? Nope. I finally call to have them follow up on that service and at the end of this visit, AGAIN the tech couldn't complete the job because he "couldn't clean my AC because I didn't have a hose." On top of that, they claim I owe them $150 for the service because I wasn't a VIP member anymore. I told them this was a follow up visit and got literally YELLED at over the phone by the tech's supervisor because she "trusts my team and if you don't have it in writing, then you owe us for today. I'm done talking to you about this." The post-visit notes are a joke and illegible carbon copies of chicken scratch, so banking on having things written down is next to impossible. I called to speak to a manager about their "2 Year Satisfaction" clause on my Bill of Sale and no surprise here, I've still not received a call back. Their customer service is atrocious, their techs are condescending and use scare tactics to get people to pay for VIP memberships and expensive products, they give people the run around when they call, and I've yet to have a tech come out and complete a job the first time. This company has been nothing but disappointing and honestly more of a hassle and headache than anyone should have to face after spending $20k on their services. Please do yourself a favor and spend the massive amounts of money needed for your AC/Furnace somewhere else. read more

1 Hour Heating and Air condemned our furnace in a routine inspection and we later found out they falsified a photo of a "crack" on our heat exchanger using a furnace of another brand that they ADMITTED to. We wasted 2 hours getting a quote for $20,000 to get our furnace and AC Condenser replaced. We were told we could cancel our install with ease and we called 2 times only to tell us we weren't actually on the schedule. Finally canceled when calling the install technician directly. Everything about this company feels untrustworthy after every phone call. We went with an install elsewhere. Now, even after getting Operations and Project managers involved, now they claim it was "cracking" not cracked. They didn't do necessary tests to actually condemn it although they forced us to replace a unit that did not necessarily need to be replaced by scaring us into thinking carbon monoxide can leak out into the ducting, they just slapped a sticker on it and left. Now they are doing NOTHING to make it right or help us out. Be wary of what you're told and ASK to be SHOWN your results on the spot. Don't trust your 1st contact. Most installation technicians don't second guess the inspection technician they just install the equipment based on the 1st person's results. Always get a second opinion. read more

We have a maintenance contract ($35/month) with this company which is supposed to cover HVAC, electrical (through Mr Sparky), and plumbing (through Ben Franklin Plumbing). Plumbing and electrical have been great; HVAC not so much. They are supposed to do annual maintenance on the furnace. It was scheduled for Friday, September 13, any time between 2:00 PM and 6:00PM. Got a text from Jasmine at about 4:30 saying she was on the way and would arrive around 5:00. She did, we saw her pull up and park in front of our house, but she never got out of her van. After about 20 minutes, I saw her drive off. I called the office, but I was told dispatch was 'really busy' and they could get in contact with their tech. They re-scheduled us for September 24 - another 4-hour window, 'cause, gee, my husband and I have nothing better to do than wait around. I accepted this at the time, but now that I've had a night to sleep on it, I'll be calling them on Monday and cancelling that appointment and the maintenance contract. read more

Recently dropped our maintenance contract with this company. Called to schedule an appointment with an office lady who told us it would be on Oct. 25 from 2-6pm. Never received a confirmatory email and I called and confirmed a week previous to the appointment. One the appointment day, they neither came nor called. When we left a message that night, they never returned the call. My husband got ahold of a technician the next day , who said they were very busy but would try to get us in that day from 2-6. He called back at 5 pm and said he was too busy to come. He then connected us to an office person who was extremely rude and said they couldn't squeeze us in until November 14th. Our original call for an appointment was in early October. We decided to cancel the appointment and the maintenance contract even though we had already paid for a fall check-up. Clearly they do not have adequate staffing and don't value the customers they do have. Stay away from this company! read more

They don't service, they sell. I called for a furnace check and almost immediately the pitch started -- the furnace was old, it had some rust, there was a crack in the venting (ok, change the vent NOT the furnace). The tech droned on about all the problems. Finally, I had to demand -- just give me the cost to repair and cost to replace. Then the tech wanted to measure the house and all the windows to get the right size furnace. I said the old one heated the place quite well, so quote me one with the same output. No, he wanted to measure windows. I mentioned all this to a friend who had an even worse experience -- hardcore sales, overpriced service and then a heat exchanger that looked like Swiss cheese in 5 years (should have talked with her before I called One-Hour, but she was out of town). The tech did not service the furnace. He left with it not working. And instead of a $90 service call, I was charged over twice that to get an annoying, high pressure sales call. NEVER, EVER use this company. read more

In January of this year (2021) I bought a new furnace and air conditioner from One Hour Heating & Air Conditioning (Loveland, CO). I was told that final test and adjustment of the a/c would have to wait until warmer weather. That test & adjustment service call was last Thursday, and the a/c was pronounced as working correctly. Yesterday, the a/c failed completely. When I called for service, I was told that the "soonest" appointment was July 2 - 2 1/2 weeks away during the hottest days of the year. Repeated calls and emails have not changed that July 2nd date. Considering the magnitude of my investment with One Hour Heating & Air Conditioning, and that that investment is fully paid for, and that that investment was only 6 months ago and therefore the equipment is still under warranty, and that One Hour Heating & Air Conditioning inspected & tested the a/c less than one week ago and pronounced it working properly, One Hour Heating & Air Conditioning should not make me wait 2 1/2 weeks for repair service during the hottest days of the year, even if that means finding another reputable & capable company in the area (and there are a number of them) to provide the needed repair service ASAP that One Hour Heating & Air Conditioning cannot provide. I asked them to get help from another company but that request fell on deaf ears. I am very disappointed with this company. Beware who you buy from. read more

These people are so inconsistent in the quality of service they provide. I've been allowing them to service my home's heating and cooling system for years, but now I'm done with them! And that guarantee of theirs, "always on time or you don't pay a dime" is a bunch of BS! read more

DO NOT USE One Hour Heating & Air! On December 23rd my furnace stopped working (remember how cold it was?) I should have known when the shyster showed up with no tools and took a look and said I needed a whole new HVAC system (furnace & AC). He said "we aren't the cheapest, but we aren't the most expensive either" (lies -they ARE the most expensive!) but I was desperate and purchased a top of the line $18K system. Furnace worked fine. Yesterday I turned on the AC for the first time and NOTHING. Called them and they said soonest they could come out is Wednesday. I said it is supposed to be 99 degrees tomorrow and he said that was the best he could do. Explained that this was a brand new system that isn't working... he said it will be a $45 service call and see me on Wednesday! DO NOT USE!! read more

Do not use this company. They are money hungry and unethical. They left our family without heat overnight in January. Our youngest recently turned two and he woke up crying so hard because he was freezing cold overnight. We also risked our pipes freezing. Here's what happened: Not long after moving to this house we began having One Hour come do our yearly maintenance on our furnace and AC. We bought a new AC through them a couple of years ago. They are always sales-y, trying to sell us things we probably don't need and sometimes a bit pushy, but nothing we couldn't deal with. Then just yesterday a tech came to do the yearly maintenance on our furnace, and we had a TERRIBLE experience. This furnace has worked perfectly with zero issues for the entire seven years we've lived here. All previous techs told us that our furnace wasn't the most efficient because of its age, but that it was working fine. They always did the maintenance, gave a few recommendations, and left. This tech told us our furnace was life threateningly dangerous and tried very hard to sell us a new furnace that day. He told us all sorts of unverified things about this and that being burned up and worn out and leaking this and that, and that it was extremely dangerous. He said it would be manslaughter for him to leave us in our home with that furnace turned on. He also said we damaged our furnace by sometimes closing two of our 12 heat vents. His only solution for us was to sell us an entire new furnace, today. We aren't in the position to buy a new furnace at this time, but realize we may likely consider it in the near future. Ours works perfectly with zero issues, and all of his claims of "danger" were completely unverified, so we knew we didn't need to be pushed into a purchase in a day. We thanked him for the information, said we were not prepared to purchase a new furnace today, and that we wanted a second opinion. The tech would NOT take no for an answer. He turned off our furnace and left. Before leaving he told my husband how to turn it back on "at his own risk" but neglected an important step. My husband is not experienced with HVAC and without knowing about the missing step that the tech neglected to tell him, he couldn't get it turned on. So us, a family with small children including a two year old baby, slept all night in Colorado in January with no heat at all. Our house got very cold and our youngest (just turned 2 years old) woke up crying very hard because he was so cold and I had to hold him to warm him up again so he could go back to sleep. The next morning my Dad was able to help my husband over the phone and they found there was a third step to turning the furnace back on that the tech neglected to tell us. They got it on and it again runs perfectly as before. Learn from our experience and stay far away from this company and work with someone honest and reputable instead, who doesn't lie and leave families with babies and young children without heat all night. read more

Overpriced with all repairs Then try to sell you a furnace and air conditioner when you don't need one Do NOT use this dishonest company. read more

We were rushed into buying a new furnace and air conditioner by their rep. We bit and paid at least twice what it would cost else where but it hot and we needed the air. We now are trying to get the A/C serviced and One Hour keeps canceling our appointment, saying they must move us back to service members in their very expensive service plan ahead of us. DO NOT use their services unless you want to spend a bunch of money to be ripped off! read more

Paid almost a $1,000 for air duct cleaning, they told me it would last for 4 years!!!!! Told me they would take before and after pictures, they DID NOT!!! BIG RIP OFF!!! read more

I've been dealing with this company for many years and have been paying a monthly fee for a service contract that was supposed to get me priority service for repairs. My a/c stopped blowing cold air and when I called for help when temps were reaching 100°, I was told the "first available appointment" was two weeks away, but I could keep calling to see if there was a cancellation! I found someone else who not only fixed the problem within a couple of days, but discovered the fan setting was twice what it should have been, putting unnecessary stress on the motor. I would no longer recommend this business! read more

One Hour heating is a very reputable company. We have used them for the past 20 years. Rich Conaway is an excellent person for service work he does a very good job and is very pleasant to have around. He is always good at explaining everything and you can be sure it is done properly when he is finished. read more

We purchased a new furnace, air conditioner, humidifier, some blue light air cleaner, all the warranty's that Cory offered, he was here for 4 hours selling us this system. We paid the monthly fee each month for the bi yearly checkups and had people come out every 6 months to check out the system. We told them every time that the upstairs was hot and after 3 years they did come put a mini unit in our master bedroom upstairs but left the other rooms upstairs hot. Then after 5 years of telling them the humidifier was not working they sent a new hire out and he told us that they put the humidifier in wrong and had checked it every 6 months for 5 years and lied to us telling us it was fine and worked properly. I am sure this guy lost his job. They tried to sell me an upgrade and I refused so they finally came and replaced ours with one that worked properly. Its amazing how nice it is to have what you paid for to be working. If you keep on them they will honor there warranty but they will not try to upsell you on what ever they can first and if you do not fall for it and hold them to it they will honor what they say they will. read more

I was very disappointed in what this company seems to have become. I had used them before with good results so called them to check out a furnace problem. The tech who came out told me the heat exchanger was cracked and that he would have to disable the unit as it was unsafe. He said I needed to set up a meeting with my spouse so we could evaluate our needs before he would give a price on a replacement and that the company would not participate in any bidding process because "it takes too much of our time to determine the proper unit and then let somebody else get the job." Well, I didn't waste any more of his time and called for a second opinion. The second contractor could not find any damage to the heat exchanger nor any other reason to red tag the unit. He made a few adjustments and re-did a drain line and all was fine for a little more than $100.00. I am sorry to see a company that was once reputable sinking to such tactics My suggestion: don't waste your time calling them. read more

This company advertises an "on time" guarantee. When I called for service they wouldn't give me even an estimate as to when the tech would be here - not even an indication as to whether he would arrive in the morning or afternoon. All they would tell me is that he would call when he was on his way. So, yes, they guarantee they'll be "on time" because they won't set a time! The guy who came was nice enough and talked me into a monthly subscription for yearly furnace tune-ups. Since then, I keep getting sales calls. Every time, I've asked them to put me on their do-not-call list. No luck. I finally called the company directly and was assured I would not be called again unless it was to schedule my furnace tune-up. Tonight - you guessed it - I got another sales call. That's it. I'm done with them. read more

So I called this business simply to get a quote on how much they charge to come out and do a furnace check for the winter and the guy that I talked to was extremely pushy. I didn't leave a phone number or name or a message. Apparently they have caller ID and he called me back because he saw my number on caller ID, I should've been smart and dial*67 so they can't see who's calling. Because he was so pushy and rude I would never use this business and I don't recommend them to anybody if that's the way they act simply because I called to ask a question. read more

I have used this company for years and spent literally thousands of dollars with them. I had my ducts cleaned as well as the the blower on the furnace. Later the same evening when the furnace should have turned on, it did not. We didn't notice it right away because the day was warmer. I called the 24 hour service line only to be told that they would get us an appointment "tomorrow" . I told them that wasn't acceptable, but all I got was a sorry and the same "script". They said they could not reach an on call person or their dispatch. Someone would contact me back as soon as possible. They did not. The temperature went down to 23 degrees and they only suggested I use a space heater. I have a maintenance contract with them as well which is supposed to get me priority service. What good is a 100% satisfaction guarantee and so called priority service, when the technician did something to cause the problem and then patronize a customer and not send someone out immediately to fix it? This is terrible customer service for a company who claims to have emergency service and created the emergency in the first place. I am very disappointed to say the least. read more

If I could give negative stars I would! The tech didn't call before he got there, and didn't wear a mask. In assessing our heater his service sheet said the heat exchanger was rusted, cracked, warped and in "Dangerous condition" and that the induction motor was bad. recommendation was furnace replacement at a cost of between $4000.00- 6000.00 depending on standard or hi-efficiency model! The hot surface ignition module was blinking with a 2 flash error code which is indicative of a pressure switch/sensor problem. We called another company the next day and got a tech out within an hour. He took the heat exchanger out and showed me that there was absolutely nothing wrong with it, checked the induction motor again nothing wrong. checked the ignitor, nothing wrong, assessed error code took out pressure switch cleaned it put everything back together and fired it up! Worked just like new without replacing any parts! And NO CHARGE! One hour charged us $90.00 to BLATANTLY LIE to us read more

Sold us a broiler (paid cash for it), which was to big for our home, was back 4 times to fix it, then figured out it was to big. Replaced a smaller one, but never gave us back the difference in the broiler prices, plus the hassle of it all. Looks like a mess. read more

ONE HOUR HEATING AND AIR - Northern Colorado location - Dishonest service, rude sales people and most concerning non existent customer service. One Hour Heating and Air, Northern Colorado refuses to return my calls or emails to address my customer service issue, so I will post here. I called in January for service on my furnace. The quote to fix and or replace my furnace was $3,000. I got a second opinion and was able to get it fully repaired for $500 elsewhere. Turns out One Hour told me things were broken, that were not to over sale me. I did not complain, I simply exercised my right to use another company. A month later I got an unsolicited phone call from One Hour Heating trying to sell me their maintenance plan. When I declined and the sales person tried to persuade me I started to explain why I would not use them. He interrupted me mid sentence, cut me off with a snotty "oooookkkk" and hung up on me. Worse than all that, after that call I called One Hour to let them know I did not appreciate what happened. One week later, 3 phone calls and 3 messages left AND an email sent, NO ONE at One hour has returned my call. HORRIBLE customer service to ignore a customer with a complaint. Add to that lying to me about what was broken, add to that a rude sales person telemarketing and hanging up on a customer he called.... go ANYWHERE else but here. read more

The furnace they installed at my house failed after 7 years -- the heat exchanger completely rusted through. Their technician really didn't look at it, just launched into a high-pressure sales pitch for their pre-priced, very expensive "service contract." When I called several times to complain, I did not receive a return call. They were unresponsive, expensive and seemed to have no idea what they were doing. read more

I will never do business with this Co. again. My Air Conditioner went out--my furnace was full of water, I called them and all the satisfaction I got from them was someone trying to sell me on some monthly service plan--he talked for about an hour!! I had to get another Co. to put in everything new and found out several things were put in wrong and I was near having a fire or asphyxiation!! read more
