"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

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

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.

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.

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.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.
