Frequently Asked Questions
Why is regular maintenance important?
What sort of technology comes with the HVAC systems that we carry?
Will my new furnace work differently than my old one?
Depending on how old your previous furnace was, you could experience a host of differences. Furnaces today are created to give more even and efficient heating than ever before. Modern furnaces also better regulate temperature and air flow, moving more air over the heat exchanger than older furnaces.
Additionally, new furnaces are crafted to integrate with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers offer your heating system an extra lift so it can deliver cool air around your home efficiently. Special features like variable speed motors will also help decrease noise associated with operating your equipment and easily meet your family’s airflow needs.
