"Joyce Cooling and Heating installed a new high-efficiency Lennox furnace and air conditioner. The installation looks great and was professionally completed. The furnace is working fantastic and is so quiet we can't even hear it running. We are warm and comfortable all the time and the new high-efficiency design should save us money for many years to come. The technicians answered all of my numerous questions."

"I would highly recommend Druziako HVAC Co. to anyone needing repairs and or replacement for Heating and cooling service. We lost our furnace Heating in the middle of the cold snap, these guys came out and immediately found the replacement system we needed and promptly replaced the next business day. Job completed, who does that..? The owner even called us during the night and offered to bring us a temp heat source if we needed it. Fortunately we did not. We can't say enough about the service. I would use them again and plan to for future cleaning and service. Nick ( the Owner i guess) and his guys did a great and professional job. Thank You Nick...!"

"I did not get a tune-up at all, I only got an inspection that they called a tune-up. They did not even clean the furnace. For my money they said they would send me a list of things that needed to be done, including cleaning, but I never even received that list."

"Mike was thorough, professional, and everything I could ask for in a contractor. He showed tremendous knowledge of the systems his company sells, their suitability to my house in particular, attentive to my concerns, and quick to bring rebates and other sales to my attention. If I had gone with a mini-split system, I would have used N.E.T.R. without a doubt. I remain very pleased with my interactions with Mike, even though they didn't result in a sale.

"Probably the best contractor I ever worked with. They delivered exactly what they promised, on time and without any hassle. They replaced my 24-year old oil furnace with a highly efficient gas boiler and water heater. Jeff and team organized everything, including permits, the timing of the oil tank and boiler removal, the delivery of the different heating system parts and plumbing supplies and the gas meter installation. They worked very efficiently and left the place cleaner than it was before. I can't stop admiring the wall with the new piece of art of engineering I have now in my expanded basement! I would highly recommend J. Griffin Heating and Plumbing to anyone looking for upgrading their current heating system."

"Our daughter and her husband are living out of the country, temporarily. When their leasees said the furnace was blowing cold air, we wanted the repair done quickly and at a good price. Unique Indoor Comfort Heating & Cooling responded right away and came to the property the same day we called. Very professional!"

"Things went very well. The sales process involved a home visit, discussion afterwards, and follow up by e-mail messages to determine what I needed in general, what I wanted in detail, the price, and understanding about rebates. Everything was clear, up front, and complete (for example, no additional costs showed up later). Airco was patient with me and spoke at my level. Their schedule was busy and there were a couple of misses before the installation date was agreed to. It was met without being changed by them. The installer was professional and courteous and put up well with my questions. The installation was done well in the proscribed time. Old stuff was carted away and clean up was done before departure. The air conditioner and new thermostat have worked well. It has been too warm to give the furnace a significant shake down. Airco did their paperwork for rebates and supplied me with the information I needed in a timely manner. There were a few misses scheduling the QIV test, but it was done at the agreed upon time and date. Again, in a very satisfactory fashion. My overall impression is of good, honest people.

FAQs for furnace / forced air heating system install or replace projects in Chelmsford, 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.
