"Dave Robinson and his team were terrific to work with. They installed a new central air system at our beach property. They arrived at the promised time, did a beautiful job installing the system, kept the property meticulously clean during the install and finished on time. They were professional throughout and Dave kept me abreast of his progress. I highly recommend them and would use them again in a heartbeat."

"Stellar service from a company with a well-earned reputation for solid workmanship. These guys are the real deal. Ramon was exceptionally knowledgeable and spent a great deal of time explaining what needed to be done. Once I signed the contract, everything happened at lightening speed. The servicemen showed up on time, were careful to not damage the doors, walls, or hardwood floors when they hauled in the new gas boiler and water heater, and left the basement in spotless condition. After I sold the oil stored in my old oil tank, Horizon was out the very next day to cut up the tank, clean the inside of it, and haul it onto the driveway for inspection. Not a single drop of oil was spilled. They are that meticulous about their work. A shout out not only to the remarkably zenlike Ramon, but also to Robert, who patiently and respectfully dealt with an unnecessarily finicky inspector."

"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.

"Mike took care of replacing my water and gas boiler in 2 days. We were without heat for a week-he diagnosed the problem within an hour and knew that our gas boiler was done-thanks to Clay's Climate Control.He gave my wife and I a reasonable price and the job was done in 2 days. Mike made a really stressful situation a calming experience. Thanks Mike"

Install Boiler FAQs, 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.

Costs range from $3,000 to $7,500, depending on system size and efficiency.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.
