How often should we replace the HVAC system filter? |
Here are some guidelines to follow in determining when to change your residential HVAC air filter:
- At the beginning of Heating & Cooling seasons
- During and after any significant home renovation
- After a professional has completed the cleaning of your furnace ducts
- When a decrease in flow is noticed at the registers
- When a professional HVAC technician measures a significant increase in pressure drop during Preventive Maintenance service
- Upon inspection, you note that the filter is loaded up with dust or debris or is damaged

What is the difference between a boiler and furnace? |
| A boiler uses oil, gas or electricity to generate hot water and in some cases steam, which is piped to baseboard radiation systems on the perimeter of the house or building. A furnace burns oil or gas to heat up air which is forced by a fan through a large ducted system and blown through registers in various parts of the building. Generally speaking, a cast iron boiler for a baseboard system has more than twice the life expectancy of a furnace for a hot air system. |

What is testing and balancing? |
Balancing is coordinating airflow and also the water flow (hydronics) so as to get the most efficient operation of the HVAC system as a whole.
Testing is the use of specialized instruments to measure temperature, pressure, rotational speed, electrical characteristics velocity, and air and water quantities for an evaluation of the equipment and the system performance.
