It was very easy to complete the financing process as well. Before it was installed, JLM sat down with me to review all of our available options based on the current status of our system. I feel they are very trustworthy, unlike some other "bigger" companies we've used in the past for service. Highly recommend. Thank you JLM!

Living in this area the old quote, " It's not the heat, it's the humidity" is very true. Our…read moredehumidifier stopped working and the house quickly became miserable. The A/C does a great job, but when the temperature outside is in the upper 90s and the relative humidity isn't far behind, then the house gets sticky quickly. We called Hoffmann Brothers and made an appointment with our favorite tech, Kevin G. He checked out the unit and knew exactly what it was and fixed it on the spot! The unit began working instantly and I was so happy! Thank you, Hoffman Brothers for hiring the most professional techs who are also so knowledgeable in this area. I won't use any other company than Hoffmann Brothers and will always request Kevin G.

I was really pleased by the process for getting our AC replaced. Matt worked with me on a bid for…read morethe new unit in October, and spoke intelligently about the options, where other companies did not seem as educated on the components. This bid was actually less than the competitors, and they had not been around as long as Harster! It was an easy choice. We scheduled to do the replacement in January. Jim and his team came out to do the install and addressed some additional needs to increase the air flow, make the existing unit up to proper code, and make the filter track so it fit filters appropriately. The last unit installation I'm sure was a DIY job or done by a less qualified company. Jim addressed all those issues. I was on a meeting when he was all finished and didn't get to go see the finished product until after he left. It was beautifully done and very neat.

Harster Heating and Cooling just left my house and I could not wait a second to write a review…read more This company has superior service and timeliness. My furnace stopped working and I called Harster after reading the other reviews on Yelp. The receptionist was very nice and she had a technician out in less than 2 hours. I ended up needing a new system, but two of the nicest and most informative technicians came out the very next day and completed the work. They talked to me about the system and what I can do to maintain it. The price was fair and what they quoted originally did not change after the work had been done. I would recommend this company to anyone.

The lady on the phone was very nice and scheduled a tech to come out the very next day in the morning. My time window was 8am-12am. I received a text and an email confirming my appointment. On the email link, you can also see the name and picture of the tech that will be coming out. The next day I received an alert at about 10am notifying me that the tech was on the way. The status email showed me his GPS location! I thought this was a really nice feature, it gave me an idea of about how far he was away. Justin was my HVAC tech. He wore a mask and shoe covers when he entered the house. I explained the issue I was having, and he first took a look indoors. He quickly found the problem was a leak in the evaporator coil. Justin presented me with all my options and facts and let me make my own decision. At no point was he pushy or trying to sell me extra services. I had some other HVAC questions, and he welcomed those and answered them and provided good suggestions. Since one of the options was a full replacement of my unit, on the same day I received a call from the Dole sales rep. He said he was able to come out that same day to give me some options of replacing the AC unit. He was courteous, came out, took a look, and we spoke through options. I was provided quotes on the same day within about 15 mins. I was very impressed with Dole and will definitely be using them again for any HVAC related jobs!

Backstory: I had gotten a new ac unit installed a year ago but it never ran well so I assumed it was too hot outside, bad windows, insulation issue and had purchased 2 window units to help keep it cold inside. I've known Brandon for a very long time and was just casually complaining about my HVAC issues, then he had me check some things out to find that the previous installer completely did a hack job. I was lectured about using "friends of family" who aren't properly licensed and certified...but then he fixed it for me quickly. The price was very reasonable and the amount of care and thought he put into worrying about me and the dogs meant even more 10 out of 10 would recommend him to anyone requiring HVAC services

He explained the pros and cons of repairing versus replacing our system-gave us his input on why he would suggest one model over another and suggested we search online to see what we thought. He also worked within our budget and when we agreed on a unit he and his crew were over the following Saturday to install everything. After about a week or so Brandon contacted us to make sure everything was working properly and to see if we had any questions. The young man seems very knowledgeable about his craft I would highly recommend him for your HVAC needs.

What a perfect service company. I've had the pleasure of having them come to our house a few times…read moreafter having moved in over the fall. Climate Masters have been servicing our boiler for the better part of thirty years. They knew what they were doing and were EXTREMELY informative. They showed me how our system worked, they took the time to explain everything from lighting the pilot light to bleeding the radiators. The tech even gave me a key to bleed the air from the radiators. They state they specialize in older homes and they did right by our 96 year old system! Highly highly highly recommended.

After Climate Masters finished the job, I was surprised to realize ... wow, even mechanical systems…read morecould be visually attractive. This was because the installers, Scott and Ethan, did an absolutely meticulous and exacting job. Our house is a 6400 sqft three story built in 1906. During the winter, the hvac system we had in place was never able to properly heat up the home. While driving one day, I spotted one of the Climate Masters' trucks with the motto, "we specialize in older homes" and wondered if they could fix our hvac setup. Tom came to assess and bid the job, and I must give thanks to how patient he was during the process. I took an excessive amount of time to decide, and yet Tom followed up throughout this period. Climate Masters ended up installing a large 140K BTU gas furnace, ran new black iron gas piping, and redid sections of our duct work. Part of the work involved cutting through a kitchen floor with brick veneer. Scott was able to shape the vent opening beautifully. The result was that for the first time ever, the house felt ... toasty during cold weather. When Spire came to activate the gas, servicemen on two separate occasions saw the installation and, without prompting, asked me which company did the job. When I asked why, they both said, "oh, it's because they did a great job!" Everyone I interacted with throughout the process has been wonderful: Scott and Ethan came promptly at 8 am each day and finished a huge job in 1.5 weeks; Doug was great with follow up logistics, and Jennifer always friendly and helpful with office paperwork.
