Question 1

Can a heat pump be used as the sole heating source in winter?

Accepted Answer

No, a heat pump cannot be used as the sole heating source in winter. An auxiliary heating system is required to meet heating needs in cold weather (generally below -8 to -12 Celsius, depending on the system).

Question 2

What is SEER and HSPF?

Accepted Answer

The efficiency of a heat pump is calculated based on SEER (Seasonal Energy Efficiency Ratio) for cooling and HSPF (Heating Seasonal Performance Factor) for heating. The higher the number, the more efficient the heat pump is.

Question 3

What are the components of a ductless mini-split heat pump?

Accepted Answer

A ductless mini-split (or bi-bloc) heat pump has two main components: an outdoor unit (compressor/condenser) and an indoor unit (air handling unit). A small hole (approximately 3 inches in diameter) in the wall is needed to connect the refrigerant lines between the indoor and outdoor units.

Question 4

How often should heating systems be inspected?

Accepted Answer

For oil furnaces, inspection at least once a year is recommended, with the oil filter and nozzle being changed. Soot should also be removed.

Question 5

Why is regular maintenance of air conditioning drains important?

Accepted Answer

All air conditioning units have a drain. Condensation drains must be inspected and cleaned regularly to ensure unobstructed drainage. A clogged drain can lead to water damage. It's better to address this in the spring to avoid issues during hot weather.

Question 6

What is the recommended frequency for system inspections?

Accepted Answer

It is usually recommended to have an annual inspection of your heating and air conditioning system.
