"Alpine Heating and Cooling replaced our old two-zone heating and cooling system with a new energy efficient one. The team of installers arrived as scheduled, and the installation was done quickly and professionally. Alpine applied for the permits and we passed the inspection with flying colors. Their pricing was very competitive. We are very happy with the new system and reduced utility bills."

"I had the best experience with H2Bros Plumbing and Heating. I hired them to install Navien combi unit to replace my old boiler and water heater. Genaro and Javin were very knowledgeable, professional, and polite from the start. They did an awesome job by installing all the needed parts by the code and very neat. Even though I know some plumbing companies cut corners and not install all additional components that recommended by Navien. Very reasonably priced for the job they did. I would definitely recommend them for similar jobs or any plumbing and heating projects. Please see the photo of the finished job for yourself."

"Nick and the team were working hard for 2 days trying to install the boiler and route all the pipes in a very tight space. After two days we got a new boiler which hopefully will last long. 5 years worry-free warranty from Valairco is another reason I went with this company."

"Excellent HVAC and Solar installation services! They did a great job installing a new HVAC system for us a few years ago, so we sought their services again for Solar installation. They were very professional both times: provided pricing right away, technicians were polite, and job was completed in a thorough yet efficient manner. Jobs well done!"

Replacing an outdoor air conditioner with a high efficiency, consumer reported top rated American Standard unit.  Level, wired properly, and completed beyond code and required standards.  Thank goodness for a team that cares and loves what they do AND our customers.
Great technicians who have amazing skill and are just good humans too.

"I needed a new hot water heater. I found out about Right-On Home Improvements and Plumbing through Home Advisor. The customer reviews were very good...very positive. My review will be the same. Dave and William were both professional and personable. When they came for the estimate, they spoke with me, not down to me. They listened to what my needs were and observed the work area. Within 10 minutes, they had a plan and an approximate price ( The official estimate was e-mailed to me very promptly). The work ethic and the quality workmanship were excellent! Great approach (here is the job...lets get it completed.) I worked in industrial construction for 40 years and I can tell a lot about people by the way they conduct themselves. William and Dave...wonderful! When they were finished (within the time frame that they had given me), the area was totally cleaned of any debris and the water heater operated and looked great. This is very important! The cost of the complete installation was exactly the estimate price. No extras...no add -ons. I could not have asked for a better experience...from estimate through installation. I would not hesitate to use Right-On in the future. Well done!"

Install Boiler questions, answered by experts

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

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.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.
