Sometimes, the cost of repairing an older furnace actually outweighs the cost of getting a new one altogether. In other words, it might be more beneficial and cost-effective to replace an old energy hungry furnace for one that’s far more efficient, saving you money on costly repairs and on energy bills in the future. Our team is ready and willing to come to your home, determine exactly what you need for your space, and help you find the furnace that fits best within your budget and your lifestyle.
Boilers are a popular and reliable heating option for homes in Denver, and for good reason! With high-efficiency ratings and energy-saving capabilities, boilers can save you money on your energy bills. They are also quiet and can provide comfortable, even heat throughout your home. Plus, boilers can last for many years with proper maintenance, making them a durable and cost-effective choice for heating your home.
If your boiler is inefficient, worn out, or just plain old, the simplest solution is to replace it with a modern, high-efficiency model. Old coal burners that were switched over to oil or gas are the most prime candidates for replacement. Though newer systems may be more efficient, they are often still likely to be oversized and can often be modified to lower their operating capacity.
At Sanders and Johnson, we take great pride in our decades of experience in offering the best residential boiler services in Denver. With over 40 years of experience under our belts, we have gathered experience and honed our craft to tackle any boiler repair issues you might have.
First, we’ll evaluate your needs, preferences, budget, and the unique qualities that make your home, home. Next, we’ll suggest a range of available water heater options that we know from experience will work best for you and your lifestyle. Lastly, we’ll install the water heating unit you choose according to the manufacturer’s exact specifications, ensuring that everything is working properly and efficiently before we leave. With Sanders & Johnson, you can rest assured that every last aspect of your Water Heater installation will be handled by the friendliest, smartest, and most reliable Water Heater installation experts around!
Even if your water heater is in good condition, it’s a good idea to schedule routine maintenance if you want to keep it that way. In fact, routine water heater maintenance is one of the best ways to avoid unexpected water heater failures and hefty repair costs in the future.
If your water heater has sustained multiple repairs over the last few years, chances are you’re in need of a replacement. Since the average water heater lifespan is between 8 and 12 years, 5 to 6 years is considered the halfway point. We like to encourage customers that if the cost of a repair is more than half of the cost of a replacement at the halfway point, it makes much more financial sense to replace your water heater then.
Electric heat pumps can be powered by renewable energy sources, instead of using fossil fuels, making them an eco-friendly heating and cooling system. However, electric heat pumps in Denver require supplemental heating sources because of our cold winter temperatures. In this case, we often recommend an electric or gas furnace as an addition to keep your family warm. If you're interested in learning more about electric heat pumps, in Denver, call our team for advice on whether these heating systems are right for your home!
When you notice your heat pump isn't functioning as effectively as before, it has undergone a series of repairs, and it's already old, it's high time you go for a replacement. Our team at Sanders & Johnson can assist you with a seamless and effective heat pump replacement in Denver.

Afterward, our technician will use high-value materials and parts to install your new heat pump. While replacing the heat pump, we ensure it is adequately sized and meets your home's specific layout.

We have used Sanders & Johnson since buying the home in 2018. They had installed & maintened the system for the owners previous to the people we bought it from, and did maintenance for the people we bought the home from. Tyler was the lead Tech with Johann in training on AC'c. They both were straight forward, got the job done. Side note Johann did the furnace maintenance last fall. Tyler explained about one issue with the contactor.
Although knew we don't use the AC very much and are planning on replacing the unit with in 2 years. So he suggested not replacing the contactor as it should hold until then. He was very honest that he couldn't guarantee it, but it was worth watching to see if it does.

"Honest Work for Honest Prices" is the moto on their business card and very much my experience with this company. I had 4 quotes to replace a water heater, that needed to be moved, brought up to code on several items, and to have the floo replaced out through the roof. Their price was in the middle of the quotes, though all were relatively close. I went with them b/c they took time to point out things that would need to be done "with whomever I went with" and pitfalls other people might not cover. They also brought up additional safety measures they would do on the project. As for the work itself, Erik and Quinn (who also did the quote) were on time and got the job done thoroughly and in a reasonable time & were very professional. There were no surprises on the pricing, and all the things pointed out in the quote were done, along with everything being explained to me too with the new set up. the office staff with scheduling were also really great to work with. I would 100% hire them again! ((and turns out a neighbor saw their vans at my house and has used this company for years as well))
Apr 29, 2020
Previously our Rinnai water heater went on the fritz and Wesley did a great job on the repair. This visit I had them do maintenance service our AC and again Wesley was great. I would recommend Sanders and Johnson to friends.

My daughter has a duplex in Capitol Hill that had the furnace replaced about 8 years ago. Within the last couple of years it developed a problem of starting up in the morning, running for a bit, and then shutting down. Restarting took some work. This problem was most frequent during very cold weather when the furnace was needed the most.
We had 4 different HVAC contractors (some of the most recognizeable names in Denver) investigate the problem without success. Although none could identify the problem, they all concluded that replacing the furnace was the answer to solving the problem.
Out of total frustration we started calling HVAC contractors at random and happened to get Mike at Sanders & Johnson. From the initial conversation he demonstrated in-depth knowledge of the design of furnace systems. Upon arrival for a service visit he went right to work reviewing the system design and collecting the data and measurements needed to evaluate the system. Within an hour he identified what he believed to be the problem, made a tweak to the system, and said to call him if that didn't do it.
Following Mike's visit the furnace has worked perfectly through some periods of very cold weather which would have triggered the problem. And that was accomplished with no replacement parts and certainly no replacement of the furnace.
Considering our experience with some of the most experienced and well-known HVAC contractors in Denver without success, it's hard to fully express how impressed we are with Mike and Sanders & Johnson. On a scale of 1 - 10, they are a 14.
May 16, 2019
We first used Sanders & Johnson back in 2010 for a new furnace install and it has worked great. Fast forward to 2019, Central Air stops working on hot August 95 degree day. I call them next morning at 8am and they still have me on file, can come out between 11 and 1pm - they arrive early and fix the A/C unit in plenty of time. Erik explained what was wrong, had the replacement part and had the house cool in no time! Great work and great price! Highly recommend them for heating and cooling needs!
Feb 28, 2019
S & J has been servicing our 2 furnaces, 1 AC unit and a humidifier for over 20 years. Realizing, we were on borrowed time with these units, we had Dan come out and do an analysis and pricing of what new systems would cost. He gave us 3 options and spent a good deal of time explaining each one. We made our decision and we were able to schedule the installation for the following week. Brad and Ryan came out and did a fantastic job of removing all the old equipment and installing the new.
The entire job took a day and a half (another outstanding tech came with them on the second day). They put down tarps from the entry to the furnace room so that the floors never got dirty. When they were finished all systems were tested and we received a tutorial and were given all the manuals for the products. Then they thoroughly cleaned up their work space. We highly recommend Sanders and Johnson!
Jan 08, 2019
Do yourself a favor... if you need heating and cooling work done, call Sanders and Johnson. They're honest, reliable and reputable. Very highly recommended.
Aug 09, 2018
These guys have serviced our home heating and cooling systems for the last 15 years. They have installed air conditioning and have replaced our boiler and water heater over the years. Servicing happens twice a year. They are AWESOME!!! Reliable, honest, very knowledgeable, fair pricing, great service.
Highly recommended!!
Aug 06, 2017
I have had Sanders and Johnson help me for many years in a 42 year-old condo, with a 25-year old A/C unit. Donnie especially has always been great and Josh too. More recently, Angel came in mid-June when I had to go out of town for a week with the A/C down and my two cats in the house. He solved the problem and we were cool within an hour. These people have never let me down!!
I can't forget to say Kendra, who has helped so many times with the scheduling which has been a challenge at times!
Jan 23, 2017
I called Sanders and Johnson in a panic as my 20+ year old furnace was not blowing any heat during the weekend in January. Honestly, I fully expected to be told that it needed to be replaced for $3000 and that I'd have to ask a million questions to make sure that I was being swindled. Jesse, the service tech, showed up on time (awesome #1), was professional and respectful (awesome #2), spoke to me as if I am capable of understanding basic mechanics which as an engineer I definitely am (awesome #3), and recommended a quick inexpensive repair that he had parts for on his truck (awesome #4). Jesse told me he has worked at Sanders and Johnson for over 20 years and likely installed this unit in my home (we are the 2nd owners). He is really a nice person and seemed to like his job.
Was as good of an outcome as possible to a very anxious situation. Thank you!
Mar 22, 2016
I've used Sanders and Johnson a few times now, and have always had great service! Very professional and always on time. They were able to come out same day my furnace stopped working on a super snowy day this winter.
And, I just had a new filter box created for the furnace, which turned out fantastic. Thank you Jesse!
I would highly recommend them. Very reasonably priced and seem like honest people.
Dec 19, 2014
We have used Sanders and Johnson for nearly 30 years. Recently the furnace in my mother's house died. After getting several other bids I called S&J to see if they serviced the town where my mother lives. Dan came out, gave me a bid that was much more reasonable than the ones my brothers got and had the new furnace there the next day. Tim and Josh were absolutely outstanding and had the new furnace in and operating in just a few hours. My entire family is now sold on Sanders and Johnson.
Aug 18, 2014
Professional and courteous service from Dan who gave the new furnace options and estimates to the installation crew. Receptionist was very helpful with scheduling and permit information. Would definitely recommend Sanders and Johnson.
Sep 10, 2013
We've had Sanders and Johnson install two furnaces, in our home and our rental and service both of them over the years. I usually feel like prices are fair and service is competent and problems are addressed. Some technicians do have an air of conceit but others have been totally pleasant. Overall we are happy with this company and continue to be repeat customers.
Feb 21, 2013
Did a great job fixing my furnance and installing my AC. Really good at explaining what they were doing and why. Also gave tips for making sure the Heat and AC kept running wihtout problems. Honest and fair prices. I would definately recommend to anyone!
Jun 29, 2012
My AC wasn't cooling. They came out the next day which was far better than any other company. They assumed I had a leak (which is very expenisve to check for and repair) and refilled with freon to last a little while longer while I price out new ones. One of the owners came out for an estimate for a new unit. It seemed high so I am pricing out with other companies to compare. But he took his time explaining things and how to make my unit more efficient. I loved that he took his time. Then just tonight I noticed that the freon is freezing over so I called them at 9pm on a Friday. The emergency line told me someone would call me right away and he did. This man explained what was most likely happening and then suggested ways to keep the house cool. Extremely helpful and responsive! The only reason why I am not giving 5 stars is because I felt the estimate seemed high. They also put a furnace in my old house and was very happy with them during that transition as well!
