Let's Talk HVAC

High-velocity heating and cooling systems use a special fan coil and air handling unit that generates high-pressure air forced through small diameter ducts. The main supply trunk is either a rectangular or round duct that supplies air to flexible, insulated, 2inch diameter plastic feeder ducts. Air passes through sound-suppressing tubing at the end of a … [Read More]

How Do Heat Pumps Work? Heat pumps are devices that move heat from one location to another, while only using a small amount of energy. They are typically used to heat homes or office buildings, but they can also be used to cool those same places. Generally speaking, heat pumps work in ways quite similar … [Read More]

Heat Pump Basics Heat pumps are electrical devices that take heat from one location and transfer it to another. They are not new technology, and similar devices are found in most air conditioners and refrigeration units. Heat pumps operate by circulating a refrigerant through an evaporation and condensation cycle. A refrigerant is anything that makes … [Read More]

1. Lower Energy Bills Depew residents can save money on their energy bills by installing a ductless or mini-split system in their homes. If you turn off the thermostat for the rooms you’re not using, your energy costs will go down. Each indoor unit in a ductless or mini-split system can be controlled by its … [Read More]

Why the Change? The primary driver behind the refrigerant change is environmental protection. Traditional refrigerants like R-410A contribute to global warming, and reducing their use is a crucial step toward mitigating climate change. The new refrigerants, R-454B and R-32, offer similar cooling efficiency with a much lower GWP, making them a more sustainable choice for … [Read More]
