"BUYER BEWARE: This company promises that they can handle the $800 Xcel rebate for installing a heat pump water heater, but have been unable to actually do so. In total, using this company cost us AT LEAST $1,050 over what we would have paid with a different installer. Explanation of where I got the $1,050 number (read on if ye be brave): When I first reached out to this company, they sent over Dan. Dan is great -- he has a good sense of humor, he speaks the lingo well, and he's quick to say yes to any questions (which in hindsight should have been a red flag). Questions like whether the company could handle the rebate offered by Xcel for heat pump water heaters. Questions like whether his company could hook up the water heater if there was a junction box nearby. He mentioned that they don't have electricians on staff, but that he could put me in touch with 'his guy' to set up the electrical before they installed the water heater. And here should have been red flag #2. Dan's 'guy' never responded. In fact, Dan didn't even send me the contact details -- I had to reach out to the All American Drain Cleaning office to get a number for a person that didn't reply. No problem; it's the modern day, and Thumbtack is a thing. I was able to find an electrician to install the new junction box within a few feet of the water heater. Cost for that was $566 (which I'm not including in my $1,050 number). Day of the install. A new installer comes over. Removes my old water heater, installs the new one. Everything is going well until he shows me what he's done. "Gee," I say. "It sure doesn't look like the water heater's been connected to that shiny new junction box over there." At which point he tells me that this company cannot connect electrical wiring. Fam. Fam. Now I would ASSUME that these people install a lot of water heaters. We went with the water heater that THEY RECOMMENDED. So why in the seven hells did they not inform us that we would need to bring in an electrician after the fact to actually wire the darn thing in? ESPECIALLY given that this left us in a position of either: finding an electrician to do emergency/day-of work, or going without hot water until we could find someone. We were able to find an electrician. But -- whereas the first electrician mentioned they would have thrown in the work for free if they'd been out there -- this rush job ended up setting us back another $250. Oh golly, you can bet that $250 makes it into my final $1,050 number. And by the way, I spoke with the installer to ask why he wouldn't at least tell us about the need for an electrician before he removed the PERFECTLY GOOD AND WORKING water heater, and he said it was easier to do his work without possibly rubbing elbows with an electrician. Ok, so water heater installed. Electrical wired up. It turns on and everything seems to be going alright. But here comes the real kick in the shins -- heat pump water heaters are expensive, so we'd like to get the paperwork for that Xcel rebate moving. I've called their office goodness knows how many times, but have yet to hear a peep about actual progress on the rebate paperwork. That's $800 I'm basically giving up on at this point. $800 + $250 = $1050. Thanks for listening to my TED talk."

"Over 7 weeks AND 13 visits, we were intermittently subjected to gas leaks, water leaks, no hot water or heat and error codes on our tankless water heater. They took advantage of the fact that my 2 teenagers and I had no hot water and no heat and continuously up-charged us. During that time, they charged an extra $1900 over the original estimate of $4000. All of the issues were because they failed to recognize that my existing venting didn’t match the new unit (even though they added to the venting) and because they didn’t provide drain piping to manufacture recommendations. They offered me money back and then rescinded the offer as the problems they should have caught just continued. I ended up “chatting” with the manufacturer and showing them screenshots to prove the venting was wrong. They offered a cleaning crew after I complained and already cleaned up the mess they ground into the carpet. When I asked to speak to the owner/DORA license holder, Levi Torres, I was told Levi “doesn’t take phone calls”. Clearly, he only takes your money and wastes your time."

"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 septic tank service projects in Denver, CO
Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank pro could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The cost to replace a septic tank is $7,350 for the average homeowner. This cost can range, however, from $470 to $22,500, depending on several factors. Your house size is a significant factor in the overall cost, but other things like material type impact the final price tag. For example, installing a new septic tank in a one-bedroom house typically costs $500 to $900, whereas installing a new septic tank in a five or six-bedroom home is generally $1,200 to $1,600.
The cost of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100. Location, repair type, and tank material all determine the final cost. For example, replacing the septic tank filter can be as little as $200 to $300. However, repairing septic lines costs more, averaging around $1,500.
A septic tank can typically last 15 to 20 years on average, though your system's lifespan will vary depending on the type of septic system and the materials used. To help increase your septic tank's lifespan, schedule routine maintenance and do not flush items like cat litter, cigarette butts, or paper towels.
Repairing or replacing a septic tank is a job best left to a professional. Your septic tank is an essential part of your home, and if installed or repaired incorrectly, it could lead to significant problems. Things like polluted water, property damage, and health risks to your family could all happen as a result of an improper septic tank repair or installation.
