What is HVAC?

HVAC stands for: Heating, Ventilation and Air Conditioning. It is the system that provides all of the heating and cooling services for homes, offices and buildings. Your HVAC system also provides over comfort including humidity and air quality.

How often should I service my HVAC system?

At the bare minimum, your HVAC system should be serviced at least once per year. However, CHF Mechanical recommends a maintenance check three times per year: once for heat, once for air conditioning and once for general maintenance. Our HVAC technicians will check your filters, coils, wiring and motor to make sure your HVAC system is running with the highest efficiency.

Why is regular maintenance important?

Since your HVAC system controls the quality of air in your home or building, over time the filters and ducts can get clogged with dust and dander. Regular maintenance checks will ensure all of your HVAC equipment is running clean and properly. Furthermore, this helps prevent more expensive repairs during peak seasons. For heating system or central AC maintenance inspections, call CHF Mechanical today. 

How often should I replace my air filters?

Air filters should be checked monthly. Disposable air filters (cardboard edge) are usually replaced monthly. Higher efficiency pleated filters should be replaced every three months.

What is a heat pump?

Generally, a heat pump is an all-in-one heating and air conditioning unit and can be used all year long. In the summer months, heat pumps function as an air conditioner, but during the fall and winter it reverses operation to provide warmth for your home or building. Heat pump should be serviced 3 times per year to catch any problems before it affects your electric bill. Learn more about our Heat Pump Services.

How can I lower my energy bill?
