"These folks worked hard over several days to retrofit my house with a new heat pump system. The technicians at my home and the office staff were diligent, respectful, and friendly. They made the whole process much easier with great communication. I look forward to being one of their annual maintenance customers for years to come!"

"Had them come out to tune up my Mitsubishi mini-split that was not working as well as it should. Showed up on time, took care of the job for a great price, and now it works great! I would recommend them to anyone."

"Jane's replaced my 20-year old Munchkin boiler with a super efficient, modern Rinnai. Everyone was a joy to deal with. Service was excellent. Darian, who scheduled and arranged the replacement, and Greg and Oscar (who did the work) were fantastic. Excellent service, especially since I live on Lopez Island, which is not easy to get to. Competent, good-natured, hard-working, nice folks."

"They worked with me to determine a very reasonable solution to a difficult water / heating problem I had in my crawlspace. They replaced all the flex heating ducts and insulated all of the rigid ductwork making routing updates to help ensure they all stayed dry in the future. Their estimate was fair and accurate, they completed the work on time and the quality of the work was excellent. All of the workers were very professional and respectful and they ensured that I was completely satisfied at the end."

"There was nothing wrong with the furnace. Wife had unwittingly turned a wall switch OFF (one which I hadn't even noticed in 18 years). Terry failed to see this in his initial (free) inspection, so he charged us the minimum for a technical repair service, $125. I suppose I could leave a negative review for this oversight...but you know, I hadn't noted the switch in 18 years, so I can't be too critical of him missing it in a 5-min scan. Regardless, during his inspection he found that the heat exchanger is rusted, the impeller (?) is noisy, and CO level up the flue (120 ppm) is too high, though still zero from in-house registers. He convinced me that we WILL need to replace the furnace fairly soon, but it's not an immediate emergency, so we can save up and do it next year. Yes, the immediate issue could have been identified and the switch turned ON at no cost to us, but I don't begrudge the money spent on a thorough system inspection and evaluation."

"Ned from Mast Plumbing did an outstanding job installing my gas tankless water heater. He was professional, knowledgeable, and took care of everything from start to finish. He made sure the installation was done properly, explained everything clearly, and left everything clean and looking great. The pricing was also much better compared to the larger plumbing companies, which was a huge plus. It?s great to support a local company that provides excellent work without the inflated prices. I really appreciate the quality of work, attention to detail, and customer service. I highly recommend Ned and Mast Plumbing to anyone looking for a reliable plumber!"

"My furnace broke down on a very cold day, causing my family to suffer. Dave arrived promptly on time after I contacted him and exhibited a high level of professionalism. Dave displayed impressive knowledge and skill throughout the repair process. My furnace problem was quickly diagnosed and Dave explained it to me in plain and understandable terms. I appreciated his transparency and honesty in discussing the necessary repairs and associated costs. I would recommend Dave's services to anyone who needs repair or upgrades to their HVAC system. Dave, thank you again for saving my family from a cold winter!"

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.
