Customers say: True professional

"Dillon was the scheduler and very professionally, let me know all the steps that would happen. He then called when the technician was running late because jobs were taking a bit longer. That was good news to me because it meant to me that the technician was not just going in and putting band-aids on the heating systems but taking the time to fix them. When the technician arrived, he came in with his backpack toolbox, which made me feel like he knew what he was doing (when they come in with nothing in hand, it makes me think they do not know what they are doing). Jared was the technician, and he is professional, he has had the training and experience and uses gages to troubleshoot. He got directly to the problem, focused on it, and fixed it. Absolutely the best experience with a furnace repair person. And the cost, the upfront right from the beginning, and had no curveballs thrown, it was the fairest pricing I have seen on heating repairs. Thank you so much, guys. I have already shared you with my friends!"

"We were extremely pleased with the service of FinMar Comfort. Sean was knowledgeable and professional. He installed a split heat/air conditioning unit in our sunroom so we could use it all seasons. He went out of his way to find us a unit that was reliable but fit our budget. Sean also helped us every step of the way with permits and warrenty information. Would defintely recommend FinMar Comfort"

"Came home at 5:30 after working all day to find my central air unit not working & my house at 87 degrees. With 2 small children - one having asthma, I panicked. Kenny came right out and within an hour had my unit back in business. Even checked my furnace and tested my unit to make sure everything was running the way it should. Super friendly & reasonable! 10/10 would recommend!"

"We decided to add central air to our house. I called sure-temp as they installed our furnace 4 years ago. Based on my furnace experience, I expected a quote from a polite, professional person and that is exactly what I got. Interestingly enough, I mentioned to the estimator that I felt that Sure Temp was very reasonable with their products and pricing. He said quite bluntly that they were not necessarily the cheapest but that they worked hard to support everything that they sell. To be safe, I had 2 other companies do an assessment. While a month and a half later I have yet to hear from one company, the second was $200.00 more for a similarly featured competitive model. Add the 36 month interest free financing and I am happy. To be honest, the estimators from all 3 companies were professional in their work.
Ok. Back to sure temp. The quote came to me within 2 days. After doing my due diligence, I contacted Sure Temp to confirm, got approved and within a week the install was completed. Talk about fast! The installers arrived early and were pleasant and professional. They cleaned up after themselves very well.
From the initial call through completion, everyone I came into contact with at this firm was never anything but polite, friendly and professional. I would recommend them highly.

FAQs for furnace / forced air heating system install or replace projects in North Granville, NY

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.
