"It went extremely well. Punctuality was perfect. Paying attention to details was perfect. Knowledge and professionalism were perfect. The price was competitive. We interviewed 5 different providers. Ultimately, Columbia seemed to stand out best. We tried it, and we were quite happy with the choice. The service cost was for two independent air conditioner systems ( we have a large, long house), and one new furnace."

"John is very skilled in his trade and provided our family with a very competitive and professional installation of our new heat pump and furnace system. His exceptional attention to detail was amazing. He took the time to complete the installation right to insure we will have it operational for many years to come. He was patient and took time to explain everything we wanted to know about the installation which I very much appreciated. I am very happy we chose Absolute Temp control to complete this work. Thank you.."

"ACS installed a new Bryant heat pump + furnace. The equipment is high quality and the team was knowledgeable, flexible, and willing to answer all my questions. They accommodated a change in scope on the day of install from just installing a heat pump to installing a furnace + heat pump combo. This set the team back a few hours for the last minute parts request, but they powered through a very long day and stayed until the job was finished. All customer service goes directly through the owner operator. Originally this seemed like a plus, but I think they would benefit from support staff. I needed to edit and downgrade this review after a few negative experiences. Some changes are related to issues noticed after the install. The unit was not secured to the pad outdoors and also was not attached to the house. Holes cut into the corner of the garage slab in order to pass through the lines were not patched, leaving a break in the envelope. Mark promised to follow up on both of these, but he did not send anyone out to take care of this. Mark also directly promised that our install would qualify for Energy Trust of Oregon incentives for $3000, when in fact it is clear after speaking directly with Energy Trust representatives that our install did not qualify for any amount of rebate. This promise was echoed throughout the quote and the install process. I believe that the lack of a support staff is causing some shortcutting or disorganization when it comes to managing some of these details - I would prefer to assume that ACS did not know the details of the incentive rather than that they purposefully deceived me, but I dont feel comfortable recommending them given these circumstances."

"Dr. HVAC called immediately after I had scheduled my appointment to confirm the appointment. They called to let me know when the tech would arrive and then the tech (Brad) called to let me know he was on his way. Great customer service. Brad was able to come out the same day our air conditioner went down on one of the hottest days of summer. He was very professional, quick, and courteous. He not only fixed our air conditioner, but noticed our furnace had a crack. He was thorough and offered expert advice. Dr. HVAC has gained a new loyal customer."

"Gabriel came out on a Saturday and fixed my problem so we had heat, again. Gabe was great! He is thorough and conscientious and explained everything to me, which was very helpful. He was delightful to be around. The response to my emergency was very quick. I highly recommend them."
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.
