"Excellent. I can't say enough about how pleased I am with Southern Air Mechancial LLC for my Air conditioning service needs. Out of habit, I had been using another vendor who recently told me in the last 10 days that my unit was oversized for my duct work, that it was going to take 6 hours to fix it, and was about to sell me a part with installation and labor that would have cost $1400. The tech said it would break in a year and the owner basically tried to sell me a new AC unit. Got a little suspicious after asking if my unit could be adjusted since it was a variable speed down to a 3 ton and the owner said, "well, let me send my tech again". I called Southern Air and spoke to Clint, the owner. I had purchased the unit 7 years ago and without hesitation, Clint visited with his technician, and replaced the part that was a known problem with my manufacturer. He warrantied the part and was back out in two days and had the system cooling within 2 hours. I will only use Southern Air Mechanical and now know how trustworthy they are and what excellent service they provide. You can't and will not go wrong by choosing Southern Air Mechanical for your AC needs."

"Work done was accomplished efficiently. I was disturbed that items were suggested to be added that were of dubious value or not even used in an air conditioning unit. My system has been running fine without the added items. I felt the tech was trying to run up the bill which I already felt were excessive."

"Everything went great. They were professional. They sent a video introducing who would be doing the work. They assessed the problems, gave me a fair quote & I had the whole HVAC system replaced! Excellent job. Tomorrow the owner will come and explain everything to me again & I will download the thermostat app and complete the transaction $$"

"They showed up quickly on a Monday morning with my system down. The communication and openness about the problems and how to remedy them along with quoting fair pricing was exceptional and so refreshing. They could have so taken advantage of us with temps at 80° inside and kids who couldn't sleep in the heat. The Freon needed to replace what had been lost in our system was very expensive, but welcome to the consequences of the green climate change policies. They applied a Freon leak sealant kit to hopefully patch what destroyed the motor due to the loss. It was much less than spending $10K to replace the Condenser. I highly recommend DR Air & Heat Services"

"TeamEnoch replaced my old air conditioning and heating systems, and the work they did was so good it borders on the unbelievable. Two very professional technicians showed up exactly on time, worked for 11 hours straight in really horrible conditions (a cramped attic in 95-degree heat) and did the whole job in one day! To top it off, their company’s price for all this was significantly lower than other estimates I had. This is a great company. I can see why they have won so many awards. *This review was migrated from an affiliated account on Angi with an original submission date of 10/4/2021"

FAQs for furnace / forced air heating system install or replace projects in Keller, TX

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.
