"We found Giant Plumbing, Heating, and Cooling here on Angie's List. Doug scheduled a convenient time with us to replace our water heater. He gave us a price ahead of time for his services and did not upcharge for anything. He arrived on time and was very professional and knowledgeable, as well as friendly. He was very detailed in explaining everything and even gave advice on other plumbing topics where we had concerns. The expense of our particular water heater was more than the average electric or gas water heater because we had the power vent model. Our old water heater was a State brand and we were very satisfied as it lasted us for 12 years, and he replaced it with a new State model, so we were very satisfied with that as well.
We found out he also services furnaces and air conditioning so we will also request his services for them when we need them because we feel he is reliable, knowledgeable and professional. We would recommend him to anyone looking for the services he provides.

"They were instructive and helpful and walked us through the process completely. They left no mess/completely clean and seems to have had an impact on my heating bills. I would only suggest that there be more "disclosure" on what the "deal covers" Although more work was required than the offer included it would be nice not to have a a surprise so maybe a better description of what is in and out of scope.

"We contacted them first because they had a really good rating. My husband sent an email to them at night and they called me first thing in the morning the next day. They could not come out to our area but they did spend a lot of time on the phone talking me through some suggestions. So, they did provide service. They were very down to earth and they did not talk down to me like some commercial companies tried to do. They provided a lot of free and good advices even though they could not provide the service for me. We would call them again in the future to have them actually come out if they could."

"I can't recommend Air Adviser and Joshua enough! Choose them for ANY and ALL of your HVAC issues. Here's why: Responsiveness & Punctuality Joshua was extremely responsive - he immediately replied to my request and had me setup for an appointment quickly. He confirmed the request via text and I was also alerted about his confirmation of arrival time in advance - which was exactly on schedule. Work Quality This is where Joshua saved us thousands of dollars! I had another HVAC company, Horizon, come in and investigate an issue with our furnace. The furnace was making an odd noise and not pushing out heat. Horizon sent someone out, charged me $120 for a tune-up, then told me that the furnace was originally installed improperly 10+ years ago, and that, as a result, all of the parts were breaking down and we'd need to purchase and put in a new furnace. (Not what I was expecting!) Less than 24 hours later, Horizon sent a sales rep to follow-up. He then described how the whole system was pretty much shot (it still looks very clean and new), we'd need a new furnace, new ducts, and a new AC. He was going to charge us $16k! Luckily, Joshua came a couple of hours later. He looked at the furnace and, after running a couple of tests, told me it was in good condition. He then investigated the noise and realized that because of the previous windy day, the noise made by the machine was due to the exhaust vent pulling in air, which was causing the motor to work extra hard. He showed me the issue outside, pulled up the weather forecast to confirm direction of wind, and then a compass to show that the wind was blowing directly at the vent. (It was like watching Sherlock Holmes!) The fix? A $5 PVC attachment to the outside vent. So instead of paying $16k for an overblown upsell, I was able to pay Joshua $49 for peace of mind and a life-long trustable HVAC contact. Cost & Value Again, Joshua had the lowest charge for a visit and provided great insight into the ACTUAL problem. He also clued me in to the fact that the other company is known for its ridiculous upcharges and aggressive selling. I highly recommend Joshua and Air Adviser. He's punctual, kind, intelligent, and honest. You can't find anyone better."

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.
