Behold the Difference! Every day we are invited into our customer’s homes. Into their safe place and sanctuary. Quite often this is in the midst of a concern or issue that needs to be fixed! With an extensive background that spans well beyond just the trades, we love to be different. In addition to decades of industry experience, we bring some secret sauce - we love to take all the time needed to help, to make sure you are comfortable, and to provide amazing solutions. Come BEHOLD the difference! "Unfortunately we do not service or intall swamp or evaporative coolers".

"My water heater had gone out and called and called around trying to get quotes and big company’s were trying to schedule in person quotes which I know is a strong arm to get the work done then and there because they are already at your house ect. But with Behold I had a personal direct text from them asking about my situation and all I had to do was give some info send in pictures and voilà! They gave me their quote(2300$) which also beat all the company’s(3k$+) I had heard from! They had a tech out to me ASAP. It almost could’ve been same day but I was in no rush. Hunter came in and did it all him self of removal of old and installing new in just two hours! They are great to work worth and will definitely recommend and go to again."

"DO NOT USE THIS COMPANY! I spent $14k having Front Range complete a sewer line fix on my house. Four months later the line was backing up again and Front Range was unwilling to warranty any of their work! Apparently they lost all camera footage on the sewer line scope and were not willing to share any notes on the job. I made several attempts to speak with the owner Quinn, but he ignored emails, voicemails and texts. DO NOT USE THIS COMPANY!!!"

"Jacob went above and beyond replacing my water heater. He had to move my unitized Washer/Dryer out of the "utility closet" before he could access the water heater. That in itself was an immense chore and he didn't charge me extra for it. He worked really hard getting everything done and he even fixed a few other things while he was here. He worked nonstop, I was impressed. To me, he came across as an honest, respectful man and I felt confident in hiring him to do this work for me. If I come across any other plumbing issues, I know who I'm going to call. Thank you, Jacob."

Install Boiler questions, answered by experts

Many utility companies and government programs offer rebates or incentives for the installation of high-efficiency propane boilers. These can offset upfront costs and improve your return on investment. Check with your local utility or installer for current offers. Incentives vary by state and provider, so exploring regional programs can help maximize your savings.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
