I’ve used Swan now several times during the past 12 years- for a water heater install, furnace repair, air duct cleaning, furnace service, AC service, and 3 plumbing jobs- and have never been disappointed. Most recently, just this past week, they did the most recent plumbing job. And as...

If you are looking for a company that operates its business with honesty and integrity, look no further than Bill Nance Plumbing. This is the second time in the last couple of years that we needed to call a plumber and we could not be happier with the service we received. Our hot water heater...

Applewood Plumbing was a wonderful experience with Mike! He was a life saver!! I had just gone through an awful experience with another plumbing company that left with the problem unresolved. Mike came in and picked up the pieces and fixed the problems the other company had created with my...

The company did not finish the job they started two years ago. They never addressed issues in the city plumbing inspection and never got a required heating inspection. They have left one bathroom tub unfinished, the plumbing has developed multiple leaks and the kitchen sink which never froze...

They installed a new water heater and installed new plumbing. The prices were very reasonable.

"We had S&J install a new mini-split ductless system on a floor that we couldn't get cool. We also had them analyze our current system in our townhouse, which required an upgraded cold air return duct due to a bad design by the builders. Mitch was our representative, and he did a fantastic job analyzing what we needed. Mitch provided a better, more effective solution than we had heard from any of the other vendors. Additionally, he got us a great price (after rebates) on a system that was better than the other systems we had been previously quoted. The mini-split installation was a challenge, but the installers did a great job. They took their time to create an installation that looks and operates great! The cold air return duct upgrade brought our system static pressure from 0.75 inH2O down to 0.5 inH2O total, which is nearly perfect. Our air handler is running quieter now, and we are getting more airflow through our system. I would give Sanders & Johnson 10 stars if I could!"

"Had maintenance contract with Absolute to service HVAC, electrical, plumbing twice a year. On recent maintenance visit A/C condensation line was found to be clogged due to "dirt getting into the system from lack of filter maintenance". Cost $329 to clean line which was not covered under contract (and seems a bit excessive!!). Was told filter replacement was not covered in maintenance contract. Seems to me that this would be a priority maintenance item! Technician comment on last visit 5 months earlier stated filter was "still clean" and not replaced. Needless to say we will be finding another company to do our maintenance from now on."

Whether you need an emergency repair, regular maintenance, or have a project you are planning, we are your total home solution. Service Delivered With Pride! Heating, Cooling, Electrical, Plumbing, Drain Cleaning, Septic, Roofing, Gutters, Indoor Air Quality and MORE! Look for the Home Service company offering the best service and guarantees to ensure your repair or service is done correctly the first time! 100% SATISFACTION GUARANTEE- We agree to accept responsibility for your complete satisfaction with the materials we use and the workmanship we provide. During the first year, if you are dissatisfied with our service or our people for any reason, we will do whatever it takes to make it right and correct the problem to your satisfaction. Additional Guarantees- We Value Your Safety- No Blame Game-We Value Your Time-Apples to Apples -Workmanship
"DO NOT USE THIS COMPANY. Please look at the YELP or BBB complaints, they are much more akin to what I experienced. They are certainly manipulating the Google reviews. I hired Lion to do a simple cleaning/certifying of our HVAC units as part of a sale. I was initially quoted $119, and I verified no less than 3 times with the customer service rep that the price would include cleaning and testing. When our tech showed up, he said we were misquoted and the charge for cleaning and testing would be about $450, as it was part of their "maintenance" package. They very reluctantly cut us a "deal" for just over $300. Not only was zero cleaning done, the tech did not perform a single action that could be classified as "maintenance." What we got was a diagnostic and estimate for repairs and replacement. I called to complain twice before someone finally got back to me. I was told that the tech didn't perform the cleaning because it may have damaged the unit, which was clearly a lie because the tech never told me that and actually gave me a quote to perform the AC coil cleaning, $470 (what a deal!). The rep then told me that a simple cleaning was done, but not the deep clean that I was expecting. I asked that my invoice be revised to reflect that, but was quickly blocked. Yes, they actually blocked my number after repeatedly misrepresenting both the price and work. I was shocked. I filed a complaint with the BBB, of which I discovered there are many. Hopefully they do the right thing and just give me a refund, but I won't hold my breath. Again, they are clearly manipulating their reviews on Google. Customers do your research!"

FAQs for plumbing and heating service projects in Thornton, CO
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
