"I looked at a number of different options and they had the best pricing and they also specialize in just doing central air. So they were also sort of a plumber and gas fitter, anything like that, and so they really specialized in what I was looking for. So that is sort of their core business. They were good and they did a very nice, clean job. The house was built in 1901 and so they did a great job of removing the old radiators and radiant based heat systems and replacing it with a new central air set up."

"I've used this company for a few years, beginning with an issue I had where I needed some emergency assistance with an a/c system leaking water into the house. They fixed the issue and it cost far less than I thought it would. I've also used them for a couple heating repairs, annual furnace cleaning and a/c maintenance. I am about to hire them again since the a/c system is dying and it will need replacement since it's more than 20 years old. I would highly recommend Unique Indoor Comfort to anyone in need of a good HVAC/Heating company."

"Peter did an excellent job tuning up my A/C system. He was extremely diligent in making sure my A/C unit was up to speed for cooling for the upcoming summer weather. I know I will most likely need a new system installed in the near future as this one is on it's last legs. I know who to call when I need a new A/C unit installed and it will be Peter!"

"I was having problems with my central air and when I contacted Wilmer he came out right away and fixed the problem. 128 plumbing and heating previously told me I need a new central air system which would cost around $8,000. Wilmer fixed the problem in a few hours and ended up not needing a new system and was so much more reasonable with pricing. I would recommend him to anyone. He now has all my business."

FAQs for furnace / forced air heating system install or replace projects in Chelsea, MA

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.
