"I recently had Prolific Mechanical install a new air conditioning system, and I couldn't be happier with the results. The young man who completed the installation was professional, courteous, and extremely knowledgeable. He took pride in his work, kept everything clean, and made sure the installation was done correctly from start to finish. The new system runs flawlessly and keeps the house comfortable even on the hottest days. I highly recommend Prolific Mechanical to anyone looking for quality workmanship and dependable HVAC service."

"Stacy cleaned our dryer vent as asked, and then installed 2 dimmers on an electrical switch as an added service. He communicated efficiently, was on time, flexible, honest, and friendly. We would hire him again."

"Job: We had Randy's Electric install 6 canned lights on dimmer switches and fix some on-going electrical problems that we've had. Pretty simple, one-day job. Pros: Overall we thought the quality of work was very good. The canned light installation looks great and they fixed the other annoying electrical issues without a hitch. They completed the scope of work quickly and were very accommodating to getting us on booked on their schedule. They didn't leave a mess in the house at all and it appears as though they didn't need to access the attic to run the electrical lines for the cans. We were concerned over accessing the attic because we recently had an insulation job done and we didn't want that to be messed up if possible. A pretty simple job but they got it done with good workmanship and the priced seemed fair for electrical work. Cons: There were two main issues that we had with this project, one of which may be the result of us not being up-to-date with current canned lighting technology. The canned lights look great but according to feedback I got from Randy's Electric, the bulbs are built-in LED's with the trim fixture. So, no unscrewing a canned bulb, you have to pull the entire trim fixture out with the bulb inside to replace them. We were never consulted on this at all or other canned lighting options during the quote. Apparently, it was you get these canned lights and that's it. So, every time I need to change the fixture/bulb combo I have to called Randy's Electric for support? That doesn't seem cost effective for us. Apparently, the bulb/trim fixtures are guaranteed for 5 years but what happens after that? I guess I'm on my own to figure out how to swap these bulb/fixtures in the event that they go out. The other issue was that because we had that insulation job done in the attic, we were concerned over heat loss from punching the holes in the ceiling for the cans, which is a necessary thing but can result in significant heat loss. We were never advised from Randy's about how, or even if they do, seal the canned lights for heat loss. I hope they did, and based on the workmanship, they're probably sealed them, but we thought it would be good to know for sure. So, that's the reason for the 3.5 stars for customer service. Overall, we thought they did a good job and I'd hire them again but they need to be a little bit better during the quote process about detailed items as discussed above."

"If you're looking for honest, dependable HVAC service, I can't recommend Blake enough! My central air unit was leaking and missing some hoses, and he had it fixed up in no time. He was professional, efficient, and took the time to explain everything to me. In a small town, word of mouth means everything, and Blake is the kind of person you want to support hardworking, trustworthy, and genuinely cares about his customers. If you need heating or air conditioning work done, give him a call. You won't be disappointed!"

"AC went out during a heat wave. Filled out the home advisor request at 5am and got a call from the shop 30min later saying they could come out that morning. Loved the responsiveness. Technician determined the blower motor was dead and replaced it as well as looked over the AC unit itself. Cost of parts was standard and cost of labor was very reasonable. Was treated very well in a time of desperation."

"Jason showed up on time. He worked quickly and efficiently and with great effort. He communicated well, including what the price would be up front. The problem was much more complicated than originally thought, and he might have gone slightly over the one-hour minimum charge, but he only charged me for one hour. I would recommend them. I sometimes get a gut feeling I am not getting my money's worth when having repairs done at the house, but this was NOT the case with SOS. I felt like I was being treated very fairly, and dealt with honestly.

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.
