"If i could give zero stars i would have. We paid almost $12,000 back in October for them install a new system in our home. Since then we have failed county inspection 3 times. The techs who come out all have different stories and excuses. The electrician who came out last time Donald informed us of how terrible his own company was and how he planned to quit. Me and my mother have taken countless days off work for them to come bandaid the problems instead of fixing them costing us even more money for missing work. Last Monday we failed for the 3rd time so I reached out AGAIN to the cooperate office and here we are 7 days later with no response and issue still not addressed This will be reported to the BBB, Angie's list will be reported for false advertising because the reviews under this company's name are actually for a company they bought out action 9 will be involved if this isn't the last time I have to deal with these people. It's the most unprofessional experience I've had with any HVAC company and I'm very disappointed in how they conduct themselves and their business please home owners beware!!"

Boiler Repair questions, answered by experts

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

Signs of needing a new expansion tank include visible leaks and a dull sound when you knock your knuckles against the tank (working tanks should sound hollow). A malfunctioning tank may also sweat with condensation, cause pipes to create loud noises when the system is turned off, and lead to very high-pressure readings on the boiler’s gauges. When in doubt, call for a professional inspection to find the source of the problem.

With proper maintenance, boilers last for around 15 years on average. A cast iron boiler may last longer, over 20 years, but you should always consider the efficiency of older boilers and opt to replace an old one if it’s significantly lower than newer, high-efficiency boilers. Otherwise, you’ll be spending more on your utility bills each month.

Regular inspections, cleaning, and checking of exhaust systems maintain safe operation, ensuring efficiency.

Addressing gaps and cracks reduces heat loss and improves energy use.
