Heater Replacement and Installation

Heating your home & building involves many factors. Our certified technicians understand that every factor involved, including insulation, ductwork, the size, and returns of your system, needs to work together to heat the building properly. If you are not sure about your current commercial heating system or if you need to replace or install a new unit, we are here to help you with that.

Replacing your old heating and heating equipment with new, energy-efficient models is a great start. But to make sure that you get the best performance, the new equipment must be properly installed.

Heating & Cooling FAQ

What are the most common furnace problems?

The most common cause of a furnace malfunction is the dirty or clogged filter which reduces air intake and lowers heating efficiency. Besides the filter, some other issues can be thermostat malware which is indicated by a continuously running fan, weak or flickering pilot lights that indicate excessive carbon monoxide built up, damaged heat exchanger is a costly problem which can be due to overheating, frayed blower belt which will block the fan from running smoothly, over cycling if you run your furnace too high for too long, and rattling, pinging and popping sounds related to lose panels and required duct maintenance.

Why is my heat running but not heating?

If you turn on the furnace but no heat comes out, there could be a blockage. Dust and grime obstruct airflow, and if the filter becomes too clogged, the heat exchanger can overheat and shut down prematurely, preventing your home from warming up. If the surface of the furnace filter is covered with impurities, you should clean it out, and if it is too damaged, consider replacing it. Aside from connections, improper thermostat settings can also confuse your furnace. Make sure your thermostat is set to ‘heat settings’ as raising the temperature of the heating isn’t enough.

Why won't my heat turn on in my house?

There can be more than one reason for a heater not heating your home. A common cause is extremely dirty filters which can block the airflow leading to obstruction of pipes. Also, you may not realize that your heater may have an additional switch button for safety reasons, make sure it is ON. It is also possible that the electricity supply to the heater is cut off due to a faulty breaker. Do inspect your thermostat, if it is not set on ‘auto’ or ‘heat settings, or if the temperature is too low, then the heat won’t turn on.
