"I can not say enough positive about Chris and Chuck and O 2 KOOL!! Chuck came out in early January to look at my old Trane gas furnace .. he got it going with no trouble. Now today ... during our ice/snow armageddon it went out again. I called and Chris FaceTimed with me .. looked at what was up and talked me through how to relight the system myself. Good news .. I now have heat! I strongly recommend them to anyone who needs help with their heating and cooling system! They not only helped, but assured me .. a 60 yr old woman .. everything would be OK and safe. That is a VERY rare quality!"

"Mr. Douglas Barfield was quick to answer his calls. He was very professional when talking on the phone and asking questions about the AC unit. He arrived at the time that he said it would take him to get to my location. He was able to get the unit up and running because he was prepared by having the equipment with him in his truck. I would go through him for all AC and heating needs. 10/10 recommend."

"I came home to a pool of water in my front yard. Since I had already been using Will-Fix-It for my A/C and heating maintenance, I called them to see if they could help. The first part of the project was to dig where the problem area was an assess the damage. Turned out I had an old black pipe running under my yard which was the standard when the house was built in 1976. They repaired the leak area and clamped it fully explaining that without a complete digout and replacement of the entire line I would probably have the same issue in the future. I couldn't afford a project that big at the time so I assumed the risk. More than 2 years later, the pipe burst again and luckily I had the ability to fund the project. I called Will-Fix-It again and they came back out and completed the job. I have had 0 problems with the new line and am grateful they were able to get water in my house again within just a day. Great work and I'll be using them again for many years to come."

"If you are looking for new A/C systems - look no further. The team at Enoch is the best I’ve ever seen. I have never seen a large HVAC vendor that the owner of the company came out to do the original walk through. Miles (the owner) is professional and extremely knowledgeable. Not only was his bid incredibly competitive - he also notice that we wanted to have two crews to handle the large home project we had done for new A/C and furnace solutions. The work was done all in one day and they spend extra time cleaning up after all the work was done. Then the next day Miles called me back to make sure everything was done to our satisfaction. If you are getting bids for new AC systems - you must have Enoch come out and give you a bid. I rank them a 10 out of 10. The best I’ve ever seen."

FAQs for furnace / forced air heating system install or replace projects in San Marcos, 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.
