"We recently had a new combi boiler installed by CRS Heating & Cooling System, and we found that they do excellent work at a fair price. Bob provided quotes for different brands and patiently answered all of our questions so that we could make the best decision for our family in replacing our old machine. Cody is professional, skilled, and took the time to be sure that our new combi boiler was properly installed. We are so fortunate to have found Cody and Bob at CRS Heating & Cooling System, and we plan to call on them for all of our future heating and cooling needs."

"We have been a Palmer customer for 6 years. The front office and the technicians has always been great to work with. We have been using their AC and Heating Service Plan and on automatic oil and propane fill for years and we have never had an issue. My most recent experience was today for the AC Service Plan. The technician (David) was very polite, experienced, knowledgeable and respectful of our time and home. It’s always a great experience to have maintenance conducted in you home and have the technicians give you expert advice on your heating and AC system. Our AC system is well over 25 years old and still running strong thanks to Palmer. I continue to be impressed with Palmer and will remain a customer for the foreseeable future!"

"I feel very fortunate to have my furnace failure resolved by First Choice. I knew it was in trouble last spring but I thought is was something could be fixed by a checkup. My bad! It turned out to be a leak in the 20 year old heat exchanger requiring a new furnace. I knew I was in trouble because the cold had arrived. Gregg was the first one out for eval and went over the options. A couple days later I got his estimate. A couple hours after that, he notified me of a schedule opening. My new, high quality furnace went in a couple days later. First Choice made the process painless and I learned a lot. Couldn't have asked for a better process!"

"Hometown was able to fit me into their schedule on a short notice, come in and service my two furnaces (multi family), and did so at a price point that was fair. Jordan, the owner, was the one who came out to perform the routine service, and spent the time to answer my questions and show me specifics about my furnace and water heater, which I appreciate. Looking forward to working with them again."

"Sunrise Heating and Cooling did an excellent job installing my new Rinnai tankless water heater/boiler. From start to finish, the experience was smooth and professional. The crew was knowledgeable, punctual, and took the time to explain the system and answer all of my questions. The installation was clean, efficient, and clearly done with attention to detail. Everything works perfectly, and I couldn?t be happier with the upgrade. It?s clear they take pride in their work. If you?re looking for reliable, honest, and high-quality service, I highly recommend Sunrise Heating and Cooling."

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