Mr. Sam Lunt was honest, forthcoming, through and HONEST when examining my faulty heater. He provided a reasonable estimate and repair. He was timely and communicated effectively. The new products he installed where up to code and more efficient that the prior unit. He was not a high pressure salesman. He cleaned up after the installation. He was on time and on budget. HIGHLY recommend. read more

I am so appreciative that Sam came out the same day my heater broke even though it was the evening. Although he fixed the original problem, he also found a crack that meant he had to shut it off. Another company missed finding the crack until he explained exactly where it was and showed them a picture. If it wasn't for Sam, I would still be living with a dangerous heater. read more

Today, I have been looking for find them and add this review. Because I needed them to come and look at my thermostat and by mistake I had Sam hunt in my contact :) searching ND, took me to Lunt, and then here. I called them 6/18/2024 because my AC wasn't working. I went for a walk and Sam called that he was going to be early. I rushed home, he was waiting in the drive way, I went to show him where the AC was and he told me he already fixed it! it was the capacitor and he already replaced it! And, it was reasonable. I couldn't be happier. Calling them today! thank you. read more

I'm honestly still shocked that this company rep told me that my house dropping to 59 degrees in the winter is normal and that setting the heating temp to 65 was high read more

I had the guys at Lunt come and install an AC unit in our bedroom. From start to finish, Sam and his crew were super professional, honest and a pleasure to work with. They installed the unit quickly and neatly and left our home clean. I recommend them highly! Would use again in a heart beat:) Amy Hilmer read more

With Lunt, we've found the HVAC company we'll stay with as long as they're in business. A new 2-stage Bryant furnace was installed in our home a year ago by a clueless company and it has been a total disaster from day one. Rooms too hot and too cold at the same time. A month ago it was time to install a new filter and we weren't sure how to do that with this Bryant, so we called Lunt and were immediately impressed: they answered promptly, came as scheduled, then demonstrated how to install the filter. They clearly know what they're doing. So this week we had them come back to deal with our hot-cold rooms issue. They knew why this was happening and changed the 2-stage furnace to run only in high-flow mode. We have rooms with ceilings of different heights and the low-flow mode didn't circulate the air. It came on constantly for short periods of time, trying to heat the rooms with high ceilings. That waste of gas was VERY expensive. High-flow did it! Now the warm air circulates well, the temperature in the various rooms has evened out, the furnace comes on much less often, and will surely be gas-efficient. The bonus was a genial talk I had with Mark when he had finished. read more

Sam and Mark were great to work with. Mark was efficient in the diagnosis of our Your furnace problem and returned on a separate appointment with the right parts and quickly repaired our furnace. It now runs well and is much quieter. Thanks Lunt! If there is any negative, they were a little slow to return calls after the initial contact but I made it clear that were weren't in an emergency situation (we have a wood stove) and after living in Minnesota it never really gets cold in Petaluma! I heartily recommend Lunt HVAC especially if you have York equipment installed. read more

I called Lunt Heat and AC because my propane wall furnace wasn't working. Lunt called me back the same day and explained the soonest he could come by was Monday--which I understood because it was the beginning of very cold weather. I ended up taking the unit apart and fixing the problem myself so I cancelled their appointment. Being a retired contractor in the service business for over 30 years, I appreciate good customer service and I dislike folks that don't have the courtesy to return calls. 2 other companies never called me back. I felt I was treated well with Lunt Heating and AC and would use them again. read more

Mark came out right away to check on our AC that was not cooling. He quickly diagnosed the problem and replaced a motor. He discovered that the new motor was functional, but too noisy, so he came back and replaced it. His company was recommended to us by two people. Both said he was an honest businessman. I couldn't agree more. I would highly recommend Lunt. read more

Mark Lunt came out today to look at our nonworking AC. He immediately determined the problem and went about methodically fixing the unit perfectly. I was painfully anticipating a new AC unit ($$$) but Mark was able to fix our unit. Very professional, knowledgeable and quite personable to boot. A very good find indeed! read more

In the middle of the heat wave my A/C went out. i called Lunt and they were able to come out later that day. Sam is awesome! Very reasonable, thorough, knowledgable and he fixed it in short order. i highly recommend them for all your heating and air conditioning needs. read more

VERY highly recommended. It's 111 degrees out and our central air died. Sam was here within 2 hours of our call and within an hour had us up and running! Super professional service and a very nice guy! read more

We hired Lunt Heating and Air Conditioning in May of 2021 to replace our heater and install a new air conditioner. We hired Sam because of his vast experience and knowledge and because his price was competiitive and actually lower than his larger competitors. Many of his competitors also included features that we didn't need. Sam completed the job on time and the performance of the systems have been flawless. Sam is a person of integrity and is always responsive if i have a question. I give him my highest recommendation. read more

Called Lunt Fri mid day...nice polite csp i talked with took my info and passed it to Mark whom called me within an hour or so and said he'd "swing by in a bit". I had already explained the problem so he said he'd be over ...cool! wrong! 25 min later he calls to say he doesn't feel like crawling around and I should call a plumber ( mind you it's a copper condenser line) not a leaking faucet. Don't waste your time with this co. I should have yelped them 1st. read more

Been using Lunt for the last 20 yrs for most of our Heating / AC needs (my Father in Law, who was a contractor used him whenever he needed Heat/AC work). Very knowledgeable. My wife once called another company to try and fix our AC unit, they were clueless and couldn't find the problem. Mark came out and instantly figured out what was wrong. Mark has put in our AC unit, and completed necessary repairs over the 15 yrs since it's installation...okay, he's only come out a couple of times. I've learned my lesson though and won't use anyone else. Recently, after initial contact; he was at our house in an hour and the problem was fixed soon after. Awesome! read more

We used Lunt to install our Nest thermostat last December. They did a great job and it has worked flawlessly ever since. Timely, reasonable, great work. read more

We were having intermittent issues with our heater and got a recommendation to call Lunt Heating & Air Conditioning. Even through we couldn't reproduce the issue while Mark was here, and even though there weren't any clear problems with our system, Mark was able to tidy things up and get everything running smoothly again. Our heater has been working perfectly since his visit. Thanks! read more

Mark Lunt is a highly professional individual. In my case the blower engine in the heater/AC unit had come off its mounts. If he could have welded it back on that would have been the most economical. But the proposal involved replacing the entire motor (which was quite expensive), so I figured I'd try bringing the squirrel cage to an auto shop (where they have welding tools) to reattach the broken mount and reinforce the others. The problem was in hooking everything back up. I thought I took good notes on all the hookups, but it still didn't work. So Mark came out again and helped us untrip a switch to get the furnace working again. read more

Great job. My gas furnace broke. Called the office, workman in the field called back in 20 minutes, got here an hour later. He fixed it for a reasonable fee, and explained what the problem was. He was very open and honest and shared lots of information. (p.s. don't close your registers or your heater will overheat.) read more

I have a 1930 home with limited options as to heating and cooling. I wanted AC and had been recommended to the Lunts by a friend. My first meeting with Sam began with him walking up to my home, assessing the situation, and saying, "Here's what I can do for you." He recommended a mini split system. It was the perfect solution. Working with the Lunts and their colleagues was lovely. I always felt respected, informed, and confident that the job was well done. read more

Met Mark and Sam at the spring home and garden show in Santa Rosa. Had them come out and give me a quote. They didn't present as sales people but as folks that really wanted to make it right for us. They were informative, discussed options, what would work best and what would suffice. We didn't make a decision right away and I'm glad we didn't. We actually had them replace not only our heater but also our A/C. Mark was great about providing options. I didn't want to pay much for an A/C given that we don't use it very often but wanted something that would work well. Both he and Sam did an awesome job in installation, all in one day. I would highly recommend Lundt. No fuss, no drama and very competative pricing. Totally trust them. Wish the did electrical and plumbing as well. I'd hire them in a heart beat. read more

Called as our air conditioning wasn't going on. No power. They called me back within five minutes and to our house within twenty minutes. Great service. Repaired it for us. Thanks for great service Sam. read more

With an older building here in Mendocino Avenue, it seems like every summer there is a cooling problem and every winter a heating issue. It's probably time to replace the equipment on our roof, but it will be expensive ... Lunt Heating has helped us out a number of times with fast friendly service and excellent problem solving. Our last event was no heat while we were going through a spell of 30 degree temps ... our tenants were quite unhappy, but Lunt Heating was here fast and made the repairs we needed ... happy tenants again !!! read more

They were very thorough and took the time to explain the different options for a new heater and air conditioning during the initial quote. They weren't the cheapest and not the most expensive, but were the most professional--in reference to the quality of the quote, very quick response time, and quality of work. During the job they were kind, careful to keep clean, and were a good team with each other. They even left the plastic that they put down under the house. In addition, they pointed out some other things I might want to get checked unrelated to my heating job. And, they were quick to explain questions I had about the new heater after they left. Is definitely work with them again. And, when I can afford to put in air conditioning, will. read more

We had the best experience with Lunt Heating & Air and I would highly refer them. The were very knowledgeable and made it easy for me to understand. Some other companies weren't even looking at the intake return ( which was way too small) or the air vents to see what size ducts we had ( again too small) Lunt changed all the ducts and the intake return and got the permits, did the testing. I would highly recommend them. read more

These guys are beyond useless. I wish I could give them zero stars. They've been out to my business 5 times to try and fix the air conditioner each time claiming that it's in perfect working order and 24 hours later it stops functioning. If you want your AC vented correctly by someone who knows what they're doing and actually gives a shit about their customers call anybody but these guys. I actually had to ask them to clean up the mess of venting and insulation they tried to leave in my business as well. Completely unprofessional and horrible service. read more

Upgrade on furnace in old house: I purchased a 1500 sq. ft home with a high efficiency furnace a few years old. The furnace warmed the house but when the furnace blew air the sound was so load we could hardly talk. Over the years this noise became more frustrating. Further, on cold mornings in the West County, the furnace would run for 5 minutes, shut off and then recycle, 5 on 2 off for several cycles. Reading on the Internet it was apparent the furnace was oversized and going through overheating followed by the blower cooling the furnace. The furnace was installed by the local "sheet metal company" so I called them for a quote for a furnace with variable fan and modulating fuel valve. The nice young man looked at the furnace they installed in 2004 and said I could buy another like it, 80,000BTUs. He made no measurement, didn't inspect the ducts, just shot from the hip and said, this is what you need. My wife suggested getting a second quote so I read about other furnaces, besides Carrier and selected York. Their website sent me to Lunt. I called and two gentlemen came out. We discussed the noise and they evaluated our heating system. They brought equipment to evaluate the air flow and determined the furnace was trying to force too much air through the ducting, forcing it to overheat, hence the frequent cycling. Lunt Technicians measured the air flow through the ducting and did testing, up front at no expense to me. Using these analyses, they said I should increase the duct and air venting in two rooms to gain better balance. I followed their suggestions, had them install what they recommended and am very satisfied. The furnace, a York YP9C, is virtually without sound and the smaller 60,000 BTU furnace seems correct for our home size. I highly recommend talking to Lunt and not the "sheet metal company". read more
