"Bruce really listened to how I answered his questions and designed a natural-gas fueled steam boiler system that met all the requirements with the expansion potential I requested. During pre-installation logistics and the day of installation, Bruce and his crew were on-time, courteous and professional. Their work demonstrated the benefits of hiring a fully credentialed company, skilled and experienced at their craft. They completed their work in one very long day so that I could avoid a night without heat during a stretch of very cold January days. I trust Williams & Assoc. and would hire them for additional work in my home as needed"

"John was awesome. He was professional, friendly and very knowledgeable. I had previously had some repairs done to my central air system by another company. That result was not up to my expectations. John from Quiet Corners came out, accurately diagnosed my problem, and came out within a week to install a new condenser. We now have cool air in our house. They also work with American Home Shield, which covered most of the cost of the repairs. Great Experience!!! I highly recommend them.."

"I hired them because I just moved into a house that had 5 cats and I have a bad cat allergy. The team came in, worked hard, efficiently and were very thorough. They also fixed/adjusted a few small odds and ends in my system at no additional cost. A nice team and very friendly."

"Not the best, but I guess not the worst either.
They did the door blower test which revealed different air leaks in the house. They sealed around some of the doors in the home, installed some door sweeps, caulked around baseboard registers etc. However, the work was far from consistent and less than professional in quality.
There are 15 registers / returns in the home and we were told they would caulk around them all, they caulked around 7. 2 of which the caulking was so thin that it cracked before the next morning.
There are 3 sinks in the house where pipes were supposedly "foamed and insulated" on their report. There is no additional insulation visible anywhere that I can see.
We are entitle up to 40 CFL light bulbs in the home, however, even the 30 they said they changed were not completed.
For example:
-there are 2 nightstand lamps in the bedroom. One lamp received a CFL and the other wasn't touched.
-there is a hallway ceiling light that was supposed to be changed out with CFLs, but still has the same old bulbs.
-downstairs bathroom still has all three original bulbs
-two bedroom ceiling fans that take regular "A" type bulbs all have the same bulbs
I sent an email to the gentlemen who came out to the house asking if we could at least receive the extra bulbs. He did respond and said yes, but never got back in touch with me. After the general overall experience I did not bother chasing after them for a few more dollars worth of bulbs. However, the whole point is not the money, its the fact that these were all listed on the report and not completed accordingly.
They did recommend an insulation company to come in and give us a quote and also told us about different programs offered from the state which would allow us access to rebates for making home energy improvements. All in all, I guess it helped us to know where the air leaks were in the house, but the overall performance of the team was simply sub-par. They were nice, polite and somewhat informative but by no means "wowed" me.

"My experience with Atlantic was one of the best - if not THE best - I've ever had with home maintenance and repair companies!

Since I'd never had the heating/AC ducts in my house cleaned in the 20 years I'd been here, I solicited estimated from three companies.  This one had been recommended by my oil company owner, who said that it had been recognized in the industry as doing high quality work.  All three estimates were about the same, but the owner of Atlantic, Jack Prindiville, impressed me as being far more professional and knowledgeable than the other estimators.  He patiently and thoroughly answered all my questions, and I was scheduled to have the work done very promptly.

I couldn't have hoped for better workmen than the two young men who did the work.  They were fairly young, professional, efficient, hard-working, and extremely good-natured.  They completed the job fairly quickly, but thoroughly, and left no trace of any mess.  This was an A+ experience in every way!!!

Two small notes:  Don't be intimidated by their

"The subcontract (Sears contracts the installations out) was extremely professional and courteous. The removed my old boiler and water heater and installed the new unit on the same day. I'd read other reviews that said the Sears quote was on the high side, but for us, their quote was the lowest. We replaced a 60-year old oil furnace and a 20-year old water heater."

FAQs for furnace / forced air heating system install or replace projects in Willimantic, CT

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.
