"My furnace went out and cuddly I found myself getting bids for a replacement. I don’t make large purchases without a ton of analysis to ensure the right solution for the best price. I didn’t just have a broken furnace I have air flow issues too as the rooms furthest away never get enough air. I didn’t want to just replace I wanted to solve a 23-year-old problem. Rob was out the same day walking me through options and not over selling just giving me the facts and not pushy. His approach to resolving the air flow made sense and was very conservative as he proposed small low cost/no cost changes we could implement over time after a period of observation with the new system instead of hitting me up front with new dampers etc. up and making significant changes to the air flow. Rob clearly knew what he was talking about and has likely installed himself over the years as many systems as he has sold. There were three other comparable bids and none of them were even close to the value I was to receive from Quality West. These guys don’t look at each install as just another job they take pride in their work, are extremely professional and even have some fun along the way. They were creative in their piping as I upgraded to a two-stage variable speed system that required PVC piping so the ascetics of the piping in and outside of the home mattered to me and they were conscious of that. I would much rather work with a company like these guys that are dependent on referrals instead of doing a bunch of advertising because for them customer satisfaction really matters. This is the reason for this long review as they deserve the recognition and I would highly recommend Rob and his team Bob and Dave."

"Very professional. They did an annual service check on my furnace. While doing so, they found that my filter was wrong and could have caused major damage to the furnace. They were able to find me the correct filter in a timely manner. I'll be calling them whenever something is wrong or I need another furnace cleaning/check."

"Late on a Friday night my furnace stopped working. I called Dale and he walked me through the furnace and diagnosed my problem over the phone. He was spot on with the diagnosis, and I got a new fuse and the furnace started working again. Dale is very professional and wants to help."

"My furnace stopped working and my house was at 56à ° After I posted on Nextdoor looking for a recommendation,Tony reached out to me and offered to come take a look. He came right away, knew exactly what he was doing, determined the issue, ordered the part and had me back up and running with glorious heat in no time! Being that my house is 20 years old and has the original furnace and A/C unit I wanted to get an estimate of what it might cost me to replace both. . He gave me what I believe to be a very fair price and I WILL proceed to have this service done in the spring when I have the funds. I will also be the first person to highly recommend Tony for anyone needing the services he can provide. Heâ  s a rock star in my eyes!!"

"Habib is seriously the most thorough professional we have ever had! He expertly explained the new AC/furnace system to us so we knew precisely how the system worked, before he installed anything. He was so considerate and enthusiastic and he loves helping his customers. Our A/C unit worked so well and I know our brand new furnace will be great this winter. If I could give him 10 stars I would because he was so knowledgeable and conscientious!"

"Jason Stubbings was fantastic. I have neglected to get my Furnace and AC even looked at for years and years. So glad I did. Jason identified some serious issues which I truly believe that the average HVAC would tell me all needed replacement for big $$. Jason, for each issue he encountered (of which there were many), would grab me and show me what the problem was and explain why it was a problem and how serious OR NOT SERIOUS it was, provide me an estimated cost and let me make all the decisions without feeling pressured. He told me what could wait and what is dangerous and what should just be done since he is already inside of it looking at it. He was working hard to save me the cash I felt like. With my 20yr old AC unit, he could have easily just said this needs replaced and left it. But he showed me the problems, told me why we had the problems, how to keep the AC unit going a little longer, cleaned it and got it back in working order. My furnace exhaust had a big hole in the middle of the duct fitting and was likely leaking carbon monoxide into the house for who knows how long and I wanted to save a few bucks and he told me exactly how to fix it myself. After I ran into some trouble doing it he exchanged texts with me into the evening and asked several questions, requesting pictures, to ensure I did everything safely. I expected to pay BIG $$ for all the issues he was finding and fixing for just a $136 and tuneup and inspection, he spent hours working up a sweat on both the AC and furnace and only charged another $120 in labor and $30 parts. Not sure how many great guys they have working there but I will never call someone else for my heating and air needs, and I will be asking for Jason every time. He really went way above and beyond for us in every way."

"Every step, from the estimate with the super friendly Ryan, to the final walk-thru with the always professional Gemini, was absolutely top notch. They installed a new furnace, A/C, and tankless water heater and we are very happy with the work and final outcome. The whole crew was wonderful!"

FAQs for furnace / forced air heating system install or replace projects in Denver, CO

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.
