"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."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"RDS Plumbing and Heating, owned by Richard Stratton, has provided subpar services that have raised several concerns. I paid $2700 for the installation of a Roth outside oil tank and removal of my old basement oil tank. However, the installation was not completed in accordance with industry standards. The lack of an aerator, which is essential for Roth oil tanks, was discovered by my oil company. Furthermore, the Roth tank was not installed on a concrete slab, thereby voiding my thirty-year warranty. Rich also failed to complete the warranty booklets, which is a necessary step. When I asked Rich about his experience with Roth oil tank installations, he stated that he had done so multiple times. It is also noteworthy that RDS Plumbing and Heating website is currently not operational. Go elsewhere for your Plumbing and Heating projects. "

Heating and Air Conditioning questions, answered by experts

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Most AC repair technicians will take between two and six hours to carry out repairs, depending on the work needed and the accessibility of the unit. For example, recharging refrigerant lines should take one to two hours to service, while replacing a compressor, blower fan, or other major components can take five to eight hours. You can ask your AC repair technician how long they expect the job to take, but just in case, you should plan on being home and available for most of the day.

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

You should schedule a full-service AC inspection at least once a year to ensure it works properly. During this time, your local AC repair pro will check:

  • Safety components, such as carbon monoxide leaks

  • Cooling components, like coolant levels 

  • Electrical components, such as inspecting fuses and wiring

  • Complete system services, like flushing the drain line

While you can DIY some aspects, like changing your air filter, it’s imperative that you call in a pro to inspect your AC for you. Your air conditioner has refrigerant that could be hazardous to your health if not handled properly, so it’s best to let a pro with experience take on this job.

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season.
