FAQs
Why won't my central air conditioner turn on?
Many factors can cause a central AC system to fail. The first thing to check is if you have a blown breaker or tripped fuse. It can also be caused by loose wiring within your thermostat, a clogged air filter, or problems with the condensate pump.
Is a leaking boiler an emergency?
A leaking boiler is a critical emergency that requires immediate attention. Boilers can and do explode. If you have a leaking boiler, you should shut it off and shut the water supply off to stop the leak immediately. Next, request an emergency appointment with a trained professional who can properly repair the damage.
