"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 kind people both at the office and in the field. They were able to accommodate our dryer vent emergency (major blockage, exhaust backing up into the laundry room -- thanks previous homeowner) within the hour, and their price is quite reasonable, no gouging or high-pressure sales tactics. Will definitely be using them again!"

"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!"

"Top Shelf was awesome! Very professional and easy to work with. I left Applewood Plumbing for these guys because I was tired of the way they treat their "Gold" customers and of paying their premium prices. Uli and his team were great - stayed until 9pm to make sure I had a working furnace after my old one conked out. They will be my go to company from now on!"

"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!"

"We have the maintenance program with One Hour Heating and Air Con and this was our maintenance visit, included with the annual program. Jasmine did a very thorough job, inspecting the furnace AND air conditioner that One-Hour installed last year. She was very clear in explaining what she was doing and gave us some recommendations (filters, etc.) that we can do to keep these expensive appliances in good shape. Buy the maintenance, it is worth every penny."

"Jimmie Ciccone came out and in less than a half hour got my AC system back running at top performance! He cleaned the sides of the condenser grill, checked the air handler, checked on frequency of filter changes and then found that the power breaker in the panel was off (apparently turned off and not recycled by the alarm installer). Once the system was running and pressure normalized he checked the refrigerant charge and said it was perfect!! He only charged for the service fee to come out!!! This is an honest and religious man (not in the evangelical, religion-for-profit sense, but in the Christian sense)!!!!! I will wholeheartedly recommend Jimmie Ciccone and True Blue Heating and Air to everyone who needs heating and AC work!!!"

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.
