"Repairs were excellent and thorough "even well documented". The tech found units low on coolant. He identified and repaired multiple refrigerant leak points. I have dealt with many HVAC contractors over the years and Freedom Air Mechanical is one of the best. I highly recommend."

"These guys are the best! They taught me so much about my home HVAC system, both the pros and cons. They take so much pride in the results they provide it is almost as if they were the ones that installed the system in the first place even though they weren't although i wish they had because we definitely would not be having the issues we are having had these guys been in charge during the installation."

"We have been a Palmer customer for 6 years. The front office and the technicians has always been great to work with. We have been using their AC and Heating Service Plan and on automatic oil and propane fill for years and we have never had an issue. My most recent experience was today for the AC Service Plan. The technician (David) was very polite, experienced, knowledgeable and respectful of our time and home. It’s always a great experience to have maintenance conducted in you home and have the technicians give you expert advice on your heating and AC system. Our AC system is well over 25 years old and still running strong thanks to Palmer. I continue to be impressed with Palmer and will remain a customer for the foreseeable future!"

"Josh installed a new water heater, provided us with instructions on proper use and maintenance and has serviced it since. He is honest, thorough, and trustworthy. He also maintains my dad’s HVAC needs too. He has come out for emergency calls too. Suggest things to prevent future additional repair expenses. His prices are reasonable, especially for the personal, friendly customer service and service provided. I would highly recommend Northwoods HVAC."

"I am a big fan of Heritage. We needed to replace our broken furnace and I got quotes from five different HVAC companies, all of which had many 5-star reviews. Heritage was the best, by far, for a few reasons: Dexter, the HVAC project manager from Heritage, was professional and patient. He answered all of my questions, applied no sales pressure, helped me customize the job to my budget and needs, and even brought us space heaters to keep the house warm since we had no heat in winter. Heritage was one of only two companies to actually take detailed measurements of my home before recommending a furnace size and submitting an estimate. Three of the companies just eye-balled it and recommended furnaces that were twice the size of what Heritage recommended. Some of them told me I had to replace my entire heating and cooling system or I would have major problems (which Dexter debunked). If an HVAC project manager does not bother to measure your house before recommending a furnace size, you should be concerned. Dexter helped me every step of the way with the HEAT loan and furnace rebate process. Dexter worked around my busy work schedule and communicated in person, phone, email, and text, depending on what was best for my workday. After the furnace was installed, the house got uncomfortably dry and we realized we needed to add a whole-house humidifier (which Dexter had recommended originally). Heritage was able to come out the morning after we called and put in a humidifier and the house was comfortable within a day. The Heritage install and service guys (Fran, Bob) were professional, patient, and courteous from start to finish. The installation site was clean and well-labeled. They checked in with me and explained important items along the way. The Heritage office staff are always reachable and helpful with any scheduling, billing, or follow-up questions. The only drawback is they are definitely a premium brand and charge on the higher end for their work. They quoted higher than any of the other four companies. That said, I was able to negotiate the price and I was happy to pay a little extra for a job well done, a strong warranty, and professional service. Honestly, Heritage won me over and I will only use them in the future for my HVAC needs. They were transparent and professional and I never felt like I was getting hustled (unlike a few other big-name brands). Now I recommend Heritage to everyone I know."

Heating and Air Conditioning questions, answered by experts

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.

There are plenty of different not-so-great sounds to hear from your air conditioning unit, like squealing, grinding, water running, excessive gurgling, banging, and clanking. Each of these sounds can indicate a different malfunction with your unit, so it’s important to have a professional assess the problem before it gets worse.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.
