"We have been pleased by the service and professionalism of Rusty and his team at Cool Heat 365. Rusty was very responsive from the beginning answering all our questions. His team showed up on time did an amazing job on the install of a new furnace and AC system. They did such a good job we went back a few months later to have Cool Heat replace our hot water heater. Rusty even came by after his day later in the evening ( after 8pm) after the water heater install was complete to check and make sure everything was working well. Emilee and Jonathan Bench"

"We'd used them four years ago to replace our windows. They were about 40% the cost of Renewal By Andersen for the same Andersen windows, were professional and courteous throughout the process, and we haven't had a single problem since. So when we wanted to put in a heat pump system for efficient heating and cooling they were high on our list. We got four bids, and once again they were the least expensive, in this case by a 30% margin. They explained our options well, came up with some creative solutions (we're an old house with old vent-work which they bypassed for the ductless pumps but used for a top quality air filter), and did the job quickly and efficiently. They've checked back a couple of times since to make sure everything is ok, which it is, and it's been really nice to heat our bedroom on some cold nights and cool my western facing home office on some sunny afternoons). When the permit inspector asked before they came over who our installer is and I told them, they said "They do really good work." Definitely recommend them to others and in fact already have."

"G&S Heating is the best of the best! They just replaced our 1995 Lennox furnace that they installed with a 2020 Lennox furnace. The crew was phenomenal in craftsmanship and attitude. Our furnace is in the tight crawl space under our home which is a pain in the @#*! They really worked well together and it was so cool to learn that one of the guy's father had installed our furnace back in 1995 and he is still with G&S! Their entire operation focuses on customer service and satisfaction from the phone contacts to the sales reps to the job planners and finally the installers! I am giving G&S my highest recommendation and will have them install our new Kohler 20KW whole house generator soon. Thank you G&S... Tom H"

FAQs for furnace / forced air heating system install or replace projects in Oak Harbor, WA

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.
