A heat exchanger in your furnace transfers heat from fuel to air, providing space heating throughout your home.

Heat pumps provide both heating and cooling, using outdoor air or ground temperatures for energy-efficient climate control.

HCR measures a heat pump’s capacity to heat effectively in cold conditions, with 70% as the baseline for cold climates.

Horizontal flow furnaces release air horizontally, ideal for tight spaces like attics or crawl spaces, providing versatile heating.

HSPF2 measures a heat pump’s heating efficiency across a season; higher values mean more efficient heating.

A humidifier adds moisture to indoor air, preventing dryness and improving comfort and air quality.

A humidistat monitors and adjusts humidity levels, maintaining optimal indoor comfort and preventing excess dryness.

HVAC stands for Heating, Ventilation, and Air Conditioning, encompassing systems for indoor climate control and air quality.

An HVAC damper controls airflow in ducts, helping direct air to specific zones and enhancing energy efficiency.

HVAC sensors monitor system performance and conditions, relaying data to maintain optimal temperature and airflow.

A hybrid system combines a heat pump with a furnace, switching between the two for efficient year-round heating and cooling.

HFOs are eco-friendly refrigerants designed to replace older, harmful AC refrigerants with a lower global warming potential.

A hygrometer measures indoor humidity levels, showing how much water vapor is in the air for optimal comfort.
