    Our services

    Regular Gas Waterheater Replacement & Installation

    Waterheaters have an average age of 7-15 years;

    Over time, sediment & wear will cause it to become inefficient & produce less hot water.

    With us, we check your current waterheater to see what the issue might be; if it's fixable, we'll let you know. If replacement is a better option, we'll let you know why.

    We do it all; tank, natural gas, high efficiency natural gas, electric tank, propane tank & more.

    We mainly recommend Made - in - USA units (Bradford White) to ensure a safe & efficient waterheater for you & your family, but we carry all brands.

    High Efficiency / Tankless Waterheater Installation

    Ever wanted UNLIMITED hot water?

    Now, it's possible and better than ever!

    With high efficiency tankless gas waterheaters, you can have unlimited hot water in your house, 24/7 with no interruptions whatsoever.

    Gas Tankless units use a PVC flue pipe to achieve higher efficiency while giving you unlimited hot water. Electric versions do the same, but they don't any gas lines.

    We are true experts at installing high efficiency Waterheaters. If you ever wanted one, reach out to get a free estimate.

    How are we different?


    The companies with orange, pink & red trucks quote way higher prices because you, as the customer, have to bear their marketing cost. Those ad spots on the radio (every 4 minutes) cost a lot of $$$$.

    Marketing isn't our priority. We mainly care about you and your property, so we just get our business from word of mouth. No billboards, no radio ads, no mega marketing cost.

    Not only we're as qualified as the "big companies" in technical expertise and licensing, we fully surpass them in attention to detail and in our quality of work for a significantly lower cost.

    Equipment Choice

    "Big" companies spend the least amount of money they possibly can on the equipment they choose to maximize their bottom line.

    We don't do that at all.

    All the equipment we quote and install are the items we have in our own home or would do for ourselves. MADE IN USA Only. We don't use offbrands or builder models to save ourselves a few bucks.

    No Amateur technicians

    "Big" companies hire people off of craigslist and they never train them. Why would they? They're simply salespeople, not technicians. They are there to sell you a $20,000 system might not even be necessary. They don't really need to know what's wrong because their main purpose is to sell sell sell.

    Not with us. No amateurs allowed.

    Our people are all certified & have gone to school for their specific trade. If your system can be repaired and it's smarter to repair it, we'll let you know. If we tell you something needs to be replaced, we've made sure it's necessary.

    Experts you can rely on for honest information & transparent pricing.

    “Outstanding Customer Service“

    The sales and customer service was outstanding! I had A/C, furnace and tankless water heater installed-a lot of work and Af and Bruce went above and beyond to make sure the products were sized and installed correctly and I felt I was getting a fair price for everything. Where additional, electrical work was required, they provided a great contractor. Ive recommended them to others and will definitely continue to work with them for ongoing maintenance. Thanks guys!

    “Very professional & very neat“

    He did an excellent service. He came in, and he assessed the problem and fixed it very quickly. It was under an hour. He was very professional and very neat, and he was very respectful of our home.

    “highly recommend“

    We hired UniColorado to replace our central air conditioning system and we have been very happy with their work. We wanted the condenser unit moved off our back porch and into the yard, something we’d been told would be difficult to do, but they were able to accomplish the move quickly with no problems. They discussed different manufacturer pros and cons and helped us make the right decision for the best equipment for our size home. We now have them handling the upkeep on our older heating system as well. We highly recommend UniColorado for any heating or cooling work–they are very knowledgeable and always very professional.

    “friendly, professional and reliable“

    Af did an awesome job repairing our furnace this winter. We’ve had so many issues with it and Af was the only technician to get to the bottom of the issue without over complicating any aspect of the process. They were there for us any time with any questions we had and showed up quickly when we needed them. Aydin was also friendly, professional and reliable whenever we called about pricing questions and scheduling issues. UniColorado will be our go-to company the next time we need to service our air conditioner or furnace!
