"Huft Home Services replaced my regular HVAC company when the owners retired. Comfort Master had installed my system in 1995 so we had a 25-year personal relationship. Ed and Donna were still using hardcopy records. When I called Huft on May 12 and talked with Elizabeth, we were able to confirm and establish the status of my ongoing services. We discussed the 2 different areas of work needed, HVAC regular maintenance and an urgent plumbing service for a leaking irrigation valve system. We scheduled the irrigation repair quickly, but I was very disappointed to discover that the repair person was unable to do that work and found out that Huft actually did not work on irrigation. Fortunately I was able to find a provider who came out the next day and did exceptional work – I highly recommend Authentic Landscape/Salvador Gallardo for that work. However, rather than make a complaint, I figured I'd wait to see how the HVAC service went. That appointment was scheduled for a couple weeks later. Anthony was fantastic. He called to let me know he was running late from his previous job. Maybe it was just because I wasn't up on current services, but I am highly impressed that he was able to take many photos of my system and his work – and instantly email them and my invoice to me! He went over in great detail the status of the equipment and anticipation of potential repairs needed over time along with likely cost estimates. We also discussed possible replacements for when I decided I was ready for a new unit. I will certainly continue my maintenance with Huft, and not just because I'm prepaid for a couple more years of biannual services."

"Smart Heating and Air Conditioning was very responsive and came out when we really needed them. We were without heat as our old furnace no longer worked and our AC was on its last leg. Mike came out to give us a quote which was the best out of three that we had. He went over all options with us and now we are very satisfied to have a new and efficient heating and AC system. They lived up to their name as well, by upgrading my thermostat to a WiFi one that added that SMART touch to my system."

"Appointment was scheduled between 8am-4pm. Waited all day for the tech (Jeremiah) to arrive. Then received a phone call a little after 3pm indicating they needed to reschedule for the next day almost at the last moment. Needless to say, we got off to a rocky start, but Jeremiah did finally show up around 5pm, isolated the problem in less then 5 minutes, showed me what to do and what not to do when changing batteries out of the thermostat, and pointed out which fuse had blown keeping the furnace from coming on. In conclusion, they made this right, I received a well-needed lesson on minor furnace maintenance, and was able to get the furnace working again. Would I hire this company again? Absolutely, and if you are having problems with your furnace, you might want to consider these people as well!"

"I was fortunate to receive service on the same day I called. My issue was difficult to diagnose, as many have tried before. They were willing to step in and try to resolve my issue for good. They were successful at their first attempt. I am grateful to Guerrero Heating & Air this Labor Day weekend of 100*F+ weather."

"Jim's Air Systems had the best value for my dollar. They supplied me with better equipment than they quoted for the same price. They completed the entire installation in about five hours. They protected my floors with tarps and were very careful to protect my walls as they moved equipment in and out. Josh, the son of the original Jim, was on the job working with the other two installers. They performed above my expectations. They left my home and yard as clean as if they had never been there. The new furnace is wonderful and is already saving me money on my P.G. & E. bill. I would recommend Jim's Air Systems unconditionally to anyone in need of a new furnace and AC system. This is a family business that has been supplying and installing systems since 1976. They take personal pride in doing an excellent job. They did not sell me anything that I did not need and provided me with a much cleaner and easier-to-service installation than my existing system. They are the best!"

"Truthfully, we had angst about calling for service because of past experience with other HVAC vendors. They always said the same thing, our system is "old" and we need a new one. Very expensive! We called for service, not a hard sell! Hence, we never used the same one twice. However, Tyndall gave me the impression, whether right or wrong, that they would be less likely to do this so I decided to try them. They kept me informed of their arrival status, since they squeezed me in at the end of their work day the same day I called. So, communicative and accommodating! After running several tests, they determined it was an electrical problem and nothing to do with the unit itself. They also said our unit doesn't need replacing - that's a first! They didn't do any unnecessary service or repair to run up the bill or even try to convince us it was needed. We were only charged the minimum fee as quoted. We were able to repair our air conditioning without the "hard-sell angst". So, thorough and honest! Unlike the other HVAC vendors we've used, we definitely will call them if we need service again!"

"Juan and his team were top tier professional. From the initial consultation to the hvac installation, they handled everything with care. Juan was so thorough answering my questions, the install was done in time, and everything was to spec. When I contacted him with an issue after install, him and his business partner came to take care of things immediately. I wouldn’t hesitate to recommend them in a heartbeat. So grateful for the work they did with removing our furnace and installing a split unit heat pump. Thank you Juan!"
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.
