"I am not a review writer at all, however, I felt it only fair to write a review for Eric and Just Rite HVAC after a wonderful experience. This company and Eric the owner are, in a word, the BEST! I needed main floorâ s central AC replaced. A friend recommended me to Eric. I texted him and he responded with a few hours. setting up an appointment was fast and easy. Eric was knowledgeable and timely. My job was extremely difficult based on the location of my air handler and there was a high chance the ceiling would need to be opened for access. When Eric arrived for the job he inspected further and said he was going to try not to have to open the ceiling for access. He and his crew went well beyond what anybody else would have done and meticulously dismantled the old air handler piece by piece. It was time consuming, difficult and energy consuming. But they were able to do and saved me from having a gaping hole in my ceiling. They did an excellent job setting up the new air handler in the same location and even fixed errors the previous installer had made! The entire crew were highly professional, courteous and clean. They put down drop cloths everywhere and cleaned up everything when they were done. I highly, highly, and without reservation, recommend Eric and Just Rite HVAC and will tell anybody I know about them."

"The guys at MassAir made having to get new central AC units installed, repairs on older units, new vents and ductwork, etc., actually a pleasurable experience! It is a family owned business, and I found Joe and his son Michael to be a real pleasure to work with. They are an extremely professional, proficient, knowledgeable, honest and hardworking team, and I trust them with any HVAC related projects that I have in the future. I 100% recommend giving these guys a call for your HVAC needs! -Mike Vedder"

"I woke up the last week and my bedroom was freezing cold. I called Arvada Heating because they had really great reviews online and they didn’t disappoint us at all. They sent over a technician and within an hour or two the tech was able to restore our heat. 5 stars for Arvada!!!"

"The AC was installed in 2021 replacing an existing AC. It worked well for two seasons but I n the beginning of this season 2024, I had problems. Although the technicians that came were nice, they did nothing to fix the problem until Christian who worked tirelessly. In the future I will only ask for him. The reason for the rating is because their customer service is very good, however, I went nearly the entire summer with an AC that was malfunctioning because the first two techs could not find any problem. Also, I find their repairs costly. An example is that I paid to be in a program where they inspect electrical plumbing and hvac. No recommendation was less than $500. In fact my son used them to replace two hoses in the kitchen. Starting price for anything seems to be $500 even if they are there for 30 minutes. The choice is yours. very good customers service, nice but mediocre techs (except for Christian) and costly repairs."

"Everyone was very professional. They came and looked around and took measurements for ductless mini split ac units. They gave me a reasonable price and finished all the work in reasonable time as agreed to. Everyone was prompt and professional. They did clean work inside and outside the house and cleaned up after themselves when were done. If I ever need anymore work done I would definitely use these guys!!! Units work great! They answered all my questions abs continue to answer them as needed. Only a text away! Highly recommend!!!"

"Joe was very respectful, personable and patient and explained what he would do and why to ensure our central air would finally work. It took ALL DAY but he installed an exhaust fan in the ceiling with attic ducts to draw out hot air, performed a chemical wash of the condenser, installed a wifi thermostat that required a new transformer and taught me how to use it. I LOVE being able to monitor indoor and outdoor temps on the app and I can see that our summer tenants are using it and that the AC is working great when needed."

Heating and Air Conditioning questions, answered by experts

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.
