"So many GREAT things to say about Air-Tech. First, I had a split system installed on one side of a duplex about 10 years ago. It was permitted and passed. Less than a year later I learned there were leaks/problems with it. The original installer wouldn't come back as they no longer worked in this geographical area and the European units weren't being used. Thank God they recommended Air-Tech! They fixed the system and offered an annual maintenance check where they come out every 6 months and check for leaks, clean filters, etc. Their office is so wonderful about reminding me if I have forgotten to set up an appointment. Their guys are ALWAYS professional, clean and courteous. Well, two months ago the tenants in the other side of the duplex requested AC and I knew Air-Tech would be great. I called Alex out (what a super nice guy) and he came over the next day I think. I remember it was a Saturday. Since the price of these system had gone up substantially from when I bought it ten years I was shocked. I signed the contract and gave him a deposit but after talking to BF he suggested I get other bids for something that expensive. I called Alex and asked him to put my project on hold for a week while I looked at bids. I think he was surprised because I knew them and the system but I felt like I needed to be prudent. He wasn't rude or short. He was very respectful. The other company's estimators were pleasant enough and I learned about some options for a second gas heating system that I wanted installed at another location. The other company's prices were similar. One added a city inspection which I was doing as an added cost ot Air-Tech's price and the other company added five years of maintenance onto their price. So the prices were a bit higher. I knew I'd be purchasing the maintenance services from Air-Tech so I knew how that compared. I called Alex back about a week later and said: "Let's go. Thank you for the time to check around and feel confident. Armando and Andrew have installed the systems this week and I could NOT BE HAPPIER. I am amazed that Armando knows so much about electrical, gas and mechanical systems. Andrew is very helpful and knowledgeable and quick to make sure things are clean. Every time someone has come out from Air-Tech they are nice, neat, respectful and focused on their work. They aren't taking calls on their phone, they aren't talking excessively, etc. ANYWAY, as part of the installation for the gas wall heater they discovered that there are two gas leaks under the raised property. Someone had installed temporary shut off valves for two previously serviced gas units (a floor furnace and radiator we think). Yikes! Air-Tech was supposed to be done with ALL the work yesterday and while it's not as convenient to be at the property another day I am so thankful that they found the leak and are fixing them without charging me any money! How can they do that? I think it's because they know I'm a loyal customer. I'll be purchasing the maintenance contracts. Thank you Alex, Armando and Andrew. So happy to be working with you!"

"Ray is very professional, and provided options for my air conditioning unit replacement. Ray went out of his way to replace a small gas line leak that he found. He also drove to Anaheim early on Saturday morning to pick up a part that was needed for the AC unit, and came over to install it so that I would have the air conditioner available for the upcoming heat wave this week. He and his team were on time, and considerate during the installation process. I highly recommend RS Air Conditioning & Heating."

"The Tech went above and beyond to do my inspection and service. I did nor buy the yearly maintenance plan and I did not buy the $190. furnace filter ($20) at Home Depot. I had and still have a problem with the system. It makes a growling noise every 2 minutes or so. Thanks so much, anyways."

"I highly recommend this company. Penguin heating & Air was very quick to respond to my request, fast text reply, sent them pics, they replied with a quote, which was way lower than anyone else on this site, or even our regular guy that we normally use, we scheduled an appointment for the very next day, which was today, he also finished the job the same day! David did a very good job, very professional. Despite a terrible rainy day, he got the job done. When he was done he walked me through with exactly what he did. He also quoted me for a service on an existing unit and his quote was almost $200 less than what our regular guy charges us... We will absolutely be using this company again."

FAQs for furnace / forced air heating system install or replace projects in Glendora, CA

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.
