Word of mouth can bring business and it can cause a loss of business. I would never support Homesmart! Recently, I needed to repair my hot water heating system. As a Homesmart customer, I contacted Homesmart to find service for the repair. A Homesmart repair representative came by and said...

Needed a pressure test and repair on a red tagged gas system. Was told repeatedly by Peterson's Manager/Master Plumber that they were a flat rate company?!? More interested in the pay than the job. I was charged $3,150.00 before they would start the repairs. Estimate was for 2 men to execute...
- Janice G.
Perfect! After getting estimates from other companies for entire replacement of the boiler system which would cost up to $11,000, the problem was fixed with a simple replacement of the pump, costing only a few hundred dollars.
- Jeff B.
Went well. Ice maker repaired and made functional.
- Robert M.
Repaired furnace
- Sharrel F.
The repair went smoothly from start to finish. On-line scheduling was easy and the technician called when he was running a few minutes late. I'll use PitStop in the future.
- Bill A.
Welzig is a terrific company. We have actually used them in a previous residence as well, that had hot water heat (a boiler). They were great then and just as great this time with the air duct cleaning. The technician was very professional and able to answer my questions. It would have...

"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 boiler repair projects in Ault, 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.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
