"This company went above and beyond to help us. Our furnace stopped working and we had no heat at all. We called them and Brian came out the next morning and gave us a quote on the spot. Four days later they installed our new furnace and had us up and running in no time. I would heartily recommend this company. I know I will call them again if I have any problems in the future!"

"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!"

"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"Thank you ZACK for your professionalism taking pictures of the work you did cleaning the filters of my A/C system outside. This is the first time anyone showed me pictures of the work they did. You were kind and explained to me when was the best time to have my heating system checked and when to call to make an appt. for the fall. You were knowledgeable, caring, and I felt safe with you. What a GREAT employee to represent Palmer Gas. Also, Thank you Customer Service Rep. MICHELLE L. - you answered all questions asked of you in a friendly and professional way. That is why I stay with Palmer Gas. Heidi Ricci"

"I found Skovron Mechanical Services to be very knowledgable. They were friendly mannered. They performed their job well and did not add onto the job what was not needed. Since the a/c did not need a recharge, they did not charge for it. They were quick to explain everything to us and deducted what was not needed. They showed high respect for my aged old mother and did not try to take advantage of her old age like some companies do. It was a pleasure doing business with them. I highly recommend them to others!"

"The first really cold night of this season we had our grandchildren for a sleepover. When we turned our heat on we found that we had issues with our heating system. We called Kingdom Cooling. Gerry came over right away even though it was after hours on the weekend. He found the issue in a Very timely manner. The damage was extensive and required many hours to repair. Gerry Worked tirelessly until it was complete. The price for the repair was very reasonable and the service was top caliber. I highly recommend Kingdom Cooling for all heating system needs. I am grateful for the great service and professionalism received from Gerry!"

"Scheduling was right on point. System was installed right after Christmas. Prep process was thorough. Extremely responsive when we switched over to A/C and performance wasn’t as expected. Was a factory setting issue. Very communicative amongst their team and with us. Great follow through. Proactive annual maintenance scheduling and thorough in their system review. Would definitely use them again."

"I hired Big Alâ s Services to add additional heat to one of the rooms in my home and to do a routine maintenance on the heating system. There were a bunch of road blocks along the way found from the previous owners had Mickey moused a lot of the piping that connected to my baseboards making it impossible to do the job I sent him to do. . Al without hesitation replaced the pipes the correct way and got the total job done! Rather than coming back another day he took the needed time to stay and finish the job too. The price was fair, the work was excellent, he was honest, and spoke to me in terms I actually understood. If you need a repair, maintenance or install I absolutely recommend giving him a call!"

FAQs for furnace / forced air heating system install or replace projects in Plaistow, NH

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.
