"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."

"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."

From start to finish each employee was personable, extremely knowledgeable, very courteous, and the consummate professional.

"Kyle did a great job servicing my heat system. Brought out parts that needed to be replaced before our heat was turned on. Labor price was less than I expected and comparable to others I have used in the past. Would definitely recommend him."

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