You will then have the opportunity to try out the ideal system to make sure it is a good fit with a 100% satisfaction money back guarantee.

"Vivint is the worst company I have ever done business with. Having Vivint is a condition on my lease and, if it wasn't, I would quit in a minute. The company is so cheap about replacing malfunctioning equipment. My front door lock doesn't work and I have been working on getting a replacement for over a month. Still no luck. An appointment is not an appointment but I rough guideline to when someone may or may not show up. There are a lot of alarm companies and I could never recommend Vivint."

Boiler Repair questions, answered by experts

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Blockages can occur for various reasons, primarily linked to the accumulation of debris or substances within the heating system. Common causes include the buildup of sediment, rust, or mineral deposits inside the boiler or its pipes, hindering water flow and heat transfer. Additionally, air pockets or trapped gasses can impede circulation. In central heating systems, sludge or corrosion within radiators can obstruct the flow of hot water. External factors like frozen pipes in winter can also lead to blockages. Regular maintenance will help prevent blockages and ensure efficient boiler operation.

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.

Most HVAC systems last between 10 and 20 years, with an average life span of 20 years. The individual components within an HVAC system have their own life expectancies as well. For instance, a furnace often lasts for 15 to 30 years, while a heat pump might need replacing after 10 to 15 years.

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.
