“Outstanding Service from Start to Finish I cannot recommend Plum HVAC highly enough! From the initial estimate to the final installation, every aspect of my experience was exceptional. First, I want to express my deepest gratitude to Natalie, the office manager, who was incredibly helpful navigating the confusing and tedious rebate process. Her patience and expertise made what could have been a frustrating experience completely manageable. The owner's estimate process was refreshingly simple and straightforward--no nonsense, just honest communication and reasonable pricing. It was a relief to work with a company that values transparency. The installation crew--Ha, Jake, and Andrew--were absolutely wonderful. They arrived on time, worked professionally, and paid attention to every detail. Ha, in particular, went above and beyond: he took off his shoes while working inside despite my telling him it was perfectly fine to keep them on. After the installation, he took the time to thoroughly show me how to operate the new system and how to change the filter, ensuring I felt completely confident with my new HVAC unit. The entire team at Plum HVAC is friendly, professional, and truly committed to customer satisfaction. If you're looking for reliable HVAC service with people who genuinely care, look no further than Plum HVAC.”

“I would highly recommend Precision HVAC Heating & Air Conditioning for any services they provide. Bobby and AJ are skilled professionals that take pride in their work, are reliable, and straight up great guys. It was obvious that both Bobby and AJ enjoy what they do! They replaced my furnace which also entailed removing the access door framing. They replaced the framing with new materials and caulked the seams like the original framing. I was in the trades so I know what a good contractor is. You won’t be disappointed if you chose Precision!”

“My downstairs furnace stopped working last night. This morning I tried everything Google Gemini suggested from a DIY and realized gas valve was not working. Call Heating and Air Experts to schedule a repair. Sent them the model number and they provided a quote (a bit pricy on the part cost, but I guess that's how it works). The HVAC tech who came home was Abe. A very gentle and honest person and felt comfortable working with him. He knows what he is doing. He quickly swapped out the gas valve and then suggested to swap the controller board (both were 27 years old). He offered other types of repairs, which were a bit steep and I choose not to go forward. But he was amazing and quick in doing the work on a Sunday and get my system back up. He also helped negotiate a lower price on the controller and labor as well as maintenance service on both furnaces (he has to come back to do it). Very easy company to work with and Abe is great! Definitely recommend and suggest you ask for him, if you have any HVAC needs. Thanks Heating and Air Experts for fixing my furnace on a Sunday!!!”

Thanks again to him and his Team for their professionalism and excellent job. For our experience with AIS Heating and Air Conditioning Company, I am extremely impressed with the technicians, Fausto and Abel. Before the installation, they communicated with us thoroughly, patiently listening to our needs and offering professional advice. They addressed the removal of an old Gas Furnace and replaced it with a new Heat pump system. They worked hard, climbing into the attic and crawling through tight spaces, and did an excellent job. Once the system was in place, they carefully explained to us how to operate it. They are very professional and knowledgeable about the Heat Pump system. The installation looks tidy, and they did a fantastic job cleaning the site. Thanks again for their hard work and excellent job.

“Our A/C was nearing the end of its life and we thought about replacing it (and the home furnace) with a heat pump. I had asked a friend who had his home HVAC upgraded for recommendation(s) and he recommended FUSE, so we contacted them for a quote. Jeff came to check out the project. He was very knowledgeable, pleasant and patiently answered all our questions. He sent us three quotes and we decided to go with a Daikin heat pump system. Our installers, Andy and "Ace" were both friendly and professional. It took them two days to install the system. Our system is in the attic and they have done a really clean job with the installation. Frankly, the attic looks cleaner now than when they started! Our attic used to have a pull-string light and they replaced it with a proper electrical outlet with a switch. They didn't have to do that, but it is much nicer now. In addition they replaced an outdoor outlet with a proper GFCI outlet with a weather-proof cover. During the installation they did run into some snag with the thermostat, but they worked diligently to resolve it. During this whole process I also worked with their rebate and permit coordinator, Maria, and she was very efficient and prompt in replying to my emails. One thing I would like to see FUSE improve on is to unify their multiple CRM systems and provide a consistent number to call. Different emails had different reply-to addresses. It made some of the communication a bit confusing. In spite of that, they have been great to work with and I will definitely contact them for any future work (such as replacing the gas water heater.)”

“Jerry from TRIO heating, air, & plumbing responded to our request for help and came the very next day. We had two problems: 1) a clogged kitchen sink past the P trap from too much food down the garbage disposal, and 2) a trickier problem where a weird musty sewer smell was coming from our primary bathroom toilet. He solved both our problems, by quickly clearing out the kitchen sink, and replacing a really gross wax seal under the toilet. We are so happy with the results. As a bonus, Jerry also tested our water and fixed a pressure issue with the kitchen sink faucet. I would highly recommend working with Jerry and TRIO and I would hire them again.”

“I was a little worried when no one showed up at the scheduled time for our first appointment, but then realized I never provided them my address. I met with Israel the next day, showed him what I wanted, and he explained there was room to add a third zone to our heating/cooling system. They were able to come and do the installation earlier than expected. Ruben was punctual and a great communicator and went the extra mile when I requested he wrap one final vent strictly for aesthetic purposes. Bubak came out a few days later to wire the units and to set up the thermostat. It all went smoothly and I am super happy with the price and process. Highly recommend.”
