"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.
Great technicians who have amazing skill and are just good humans too.

"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

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.
