"Called the company on a Sunday. They arrived on Monday to give me the bad
news I had expected.  My 15 year ole A/C unit had finally died.   Later that day
I received an estimate which I accepted.  The new unit was installed on Thursday
of the same week.
 
The Monday they arrived it was very hot (when else do A/C's die). They
offered and I accepted a portable A/C loaner.  Fast response.  Professional
service. Friendly and capable people.

"It went exceptionally well! Marc was able accommodate us within an hour of our call to him.  He was courteous, professional, and knowledgeable. He was very thorough in his diagnosis of the problem, and  ordered the necessary parts immediately. Once the parts came in the next morning, he phoned to check our availability and was able to  come back and install the parts that very morning. Upon completion, prior to leaving, he ran a test of the system to assure that it was working properly.  Marc was even conscientious enough to clean up the area before he left.  His price on parts and labor were fair within industry standards. We would highly recommend him for his services."

Install Boiler questions, answered by experts

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

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.

Most installations take 2-5 days, including old system removal and setup.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model.
