How AC Works (The basics you must know)

by Michael C. Rosone |

Our theme for this month’s blogs is “Things Techs Wish People Knew About HVAC,” and that starts with a very basic understanding about how air conditioning works.

Why should you know or care how AC works, as long as it keeps your space cool?

The short answer is:

  • You should know how AC works so you understand what’s needed to keep it working efficiently and reliably
  • You’re more likely to notice sooner when something’s not working right, and call for help. In many cases, that awareness can turn small problems from turning into bigger (and more expensive) problems.

So, here’s a basic primer that explains how the most common air-cooled systems & how air conditioning works.

by Michael C. Rosone |

Trying to decide on the right ductless AC system for a NYC luxury residential or light commercial space? It pays to consider variable refrigerant flow or VRF systems for the ultimate in comfort and efficiency.

Be a Hero: Save Money on Energy For Your Business with Energy Rebates

by Michael C. Rosone |

As the demand for energy continues to rise, utility companies are offering rebates to customers as a way to reduce usage and avoid having to spend millions to construct new plants. If you are a homeowner, you may have taken advantage of some of these rebates. What you may not know is that utility companies also offer rebates to businesses that choose energy-efficient options for construction, equipment purchases and facilities operation.

It’s no surprise that utility rates on the rise again: electricity rates are expected to increase by more than 4 percent this year, and gas prices could go up by as much as 10 percent. If your HVAC equipment is getting up there in years, now may be a good time to consider replacing older units with newer models that use much less energy than older models. You can offset the rate increases by reducing your energy usage, and you can also earn you cash rebates from your utility company.Read More
