"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!"

"UIC was quick to respond and come up with the quote. Quote was very competitive against others. They were not so eager to do service on my old water heater though (I asked them to replace anode rods). I decided to go with them since their availability was good (2wks) and ratings on AngiesList were excellent while price was competitive. The job went well, though not without hiccups. I was expecting new boiler to be placed on the wall next to the foundation; though they built a new wall in the middle of the mechanical room, which costed me space; they said it will be 3K more to put in on the wall AFTER they arrived on the job with all the equipment and team. They refused to drain old water from my radiant heat system, saying I need a plumber to come for $290 per hour for 4 hours to drain the system and look for preexisting leaks. Had to hire some other plumber who took care of the problem for $215 in a mere hour. After the project was complete, system started to experience leaks. It was due to new drain connector that they decided to use for this project, and I was apparently first customer for it. After 3 unsuccessful attempts to fix the leak, they had to replace the connector, which addressed the issue. In addition, the system was eligible for rebate; however the rebate amount promised ended up being $450 less than actually paid; they quoted natural gas rebate though my system was on propane, which I told them upfront."

"I whole heartedly recommend Airco. Their team was experienced, skillful, friendly and professional throughout the duration of this job, from Joe's first visit to my home to discuss air conditioning options to Derek and Cam's final touches on the duct system. I had complete confidence in them, as well as in Steve, Danny, Frank and Patrick. Additionally, Airco's connections to MassSave and Commerce Bank meant financing and payment options to suit my budget. No more hauling loud and heavy window a.c. units up from the basement. Instead, I am enjoying consistent cooling throughout my home with no noise whatsoever. I am a very happy customer!"

"I signed up with Palmer Oil for the first time this year and have been very pleased with their service thus far. I had some issues with my furnace ad it had not been used for a long time, and was happy with the way the techs took care of all of my concerns, and at a reasonable price. Oil delivery was timely and reasonable as well, with a discount given for prompt payment. I recommend Palmer Oil to anyone looking for a reputable and reliable supplier."

"The gentleman from Kingdom surpassed every other furnace service that we have EVER had. He called within 10 minutes of our request on home advisor promised to be here within an hour and he arrived 45 minutes later. He diagnosed the problem with our furnace went to the store and returned with a new pressure release valve within a half hour. Installed it tested it, bled the lines which immediately improved the heat in a cold bedroom. I can't say enough about how totally excellent this repair man was if I could give 10 stars I would."

"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.
