"He was timely, professional and responsive. He clearly knows the technical aspects of the trade and provided us with a lot of information about the equipment he would be installing and how it would work with our existing ductwork. We did not care for his sales approach because he tried to sell us on things we did not ask for and did not need. He tried to sell us on a humidifier for the system which we really don't need because we live right by the ocean where it is quite humid year round, even in the winter. Adding humidity to our house could cause problems with mildew or mold. He also tried to sell us on replacing our hot water tank for a more efficient model even though ours is only 5 years old. We got the feeling that he was trying to pack as much sales onto the heat loan program without really thinking about the customer's specific situation, and that put off me and my husband from wanting to work with him. At the end of his sales presentation he decided on the spot he would give us an unspecified discount. We did not like this high pressure sales tactic. We had not received other quotes yet so we declined to decide on the spot. He emailed us a couple days later offering a 10% discount if we decided by a certain date a couple days later. We decided to wait beyond that date so we could get more bids.
Joe's quote was $2000 higher than a quote from another installer who has equally good reviews on Angies list. Both quotes were to install the same equipment, however the second installer included the cost of converting two unused ducts into returns and installing a pass though in a ceiling to help balance our system. I shared this information with Joe, and he responded by saying he would beat their price by $100. It goes to show that it pays to shop around.
As Airco's good reviews on Angies list attest and my interactions with him, I am sure they would do quality work, but my husband and I were totally put off by his sales and pricing approach and did not want to work with the company as a result.

"Not easy finding an HVAC company willing to install a gas steam boiler. These guys did it all and did it well, removing the old oil burner and oil tank, installing a Weil McClain boiler including steam piping and hot water, installing gas piping, electrical and plumbing, including all inspections, even leaving me a temporary hot water heater until the furnace installation was completed. They fully accommodated my schedule as well. The town electrical inspector who came after installation was complete confirmed their good reputation."

"This company has been awesome. I am a Worcester resident and have no clue about heating systems. David Clay and his team came out to look at my boiler. It was not firing. Winter is fast approaching. David provided a free estimate and also encouraged me to look at quotes from other competitors. I did. And his pricing was best aligned with my budget. His quality of work is amazing. David and his technicians fielded all my questions- I had many. Their customer service is amazing as they had all the patience and courtesy to educate me about the work and boiler systems. My experience as a customer is that Clay Plumbing Heating offers the best quality, professional craftsmanship, best client service, and at the best rates."

"The project involved replacement of a furnace and A/C. Mike was quick to come with an estimate, and had the patience to explain all relevant options, thus helping me choose the system that is right for me. Mike did a great job, and finished the work on schedule. Very professional."

"we have a crazy heating system; no one in the ten years we've had the house has really been able to figure it out. That's just life. When the heating stopped working (in January) we called Milltown. They were very responsive. We had a technician here in a day who figured out there was a leak. Finding the source, and how to isolate it was anything but simple. The tech in charge persisted (figured out, in fact that the system had been piped wrong) and solved the problem over the course of a day and a half. Many would have thrown up their hands or managed some bad technical band-aid. It was expensive (but plumbing sort of always is, and I don't think this rose to the level of unfair), but importantly the system is now better understood and there's no more leak. On top of that all of my questions were answered and the work was done well. Highly recommended."

"Shawn did an excellent job of replacing my 32-yr old heating system with a 5-zone, Buderus G115, Riello Burner, SuperStor Water Heater, and a "fan-in-a-can" air intake (as furnace is in an enclosed basement closet). He really knows his stuff! He is organized and does a neat, professional job. When he was finished, he tested and marked each zone with me for future identification. I highly recommend Congers Heating & Cooling for quality workmanship and a competitive price."

"First off, the consult was great. I was able to add services to my initial request and received a deal doing so. I also added a second set of services later that month. Adam and Steve completed the work and were completely professional and super efficient. They answered my questions and made sure I understood the work being performed. They worked with my schedule and were fantastic. I had a gas hook-up for a change from electric stove to gas stove - they even took care of the permits and inspection. They removed an old water access point for the fridge's icemaker that was in an awkward spot. They also added a regulator for the water pressure and water filtration system. Fantastic work all around. Should we need any more plumbing/gas work, I would definitely hire them again."

Converting from an oil furnace to an electric furnace isn't a simple swap—the oil system needs to be completely removed before installing the electric furnace. You'll need a full electric system installation, but you might be able to reuse existing ductwork if it's up to current safety standards. You’ll need to budget for a new electric furnace installation, which costs between $1,800 and $6,200, including professional removal, proper disposal, and safe installation of the new system.
Electric furnaces are 100% efficient at converting electricity into heat. However, some of that heat can be lost as it travels through your home's ductwork or escapes through poorly insulated areas. That's why regular duct maintenance and proper home insulation are important to maximize your furnace's efficiency and reduce heat loss, ensuring consistent warmth and lower energy costs.
With proper maintenance, an electric furnace can last anywhere from 20 to 30 years, outlasting the average gas furnace's lifespan of 15 to 20 years. To keep your electric furnace running efficiently, schedule regular cleanings, tighten connections, and have inspections done before winter arrives. With routine maintenance, you’ll ensure consistent, safe heating for years to come.
The size of the electric furnace you need depends on factors like your home's square footage, climate, and insulation quality. As a general guideline, those who live in warmer climates should multiply their square footage by 30 to 35 BTUs, while those in cooler areas should multiply it by 50 to 60 BTUs.
Consulting with an HVAC professional can help you determine the exact size that's right for your home.
An electric furnace works by converting electricity into heat using high-resistance heating elements. A blower then pushes the warm air through your home's ductwork, distributing heat evenly throughout your space. Since there's no combustion involved, electric furnaces eliminate the risks associated with gas furnaces and provide consistent, reliable heating when properly installed.
An electric furnace uses between 40 and 80 kilowatts per day to heat your home. The exact amount it uses depends on factors like your home's size, insulation, and overall energy requirements. Larger homes or those with poor insulation use more energy than smaller, well-insulated spaces. A professional furnace assessment can help confirm the ideal unit size for your needs.
