Don’t Replace It: Downsize Your Air Conditioning to Save Money. Yes You Can!

If you have an A/C system that’s more than 12 years old, it pays to replace it. Just like the technology in your computer or your car, A/C technology changes quickly. Today’s high efficiency systems allow replacement units to be smaller, more energy efficient and quieter than older systems.

The first step is to have one of our Comfort Advisers to conduct a DiPietro HVAC System Assessment™.   During that assessment we look at everything from your insulation to the sight line of your home vs the sun. Older A/C systems don’t perform well as the temperatures go above 90 degrees. Today, air conditioners provide the same cooling at 90 degrees as they do at 80 degrees. This allows us to down-size the system to save you money and energy expense. In Massachusetts, Mass Save® provides incentive rebates for homeowners replacing their cooling system with a smaller system.

In addition, simply replacing the system at the same size can cause some unexpected problems. If you oversize an air conditioning system, you’ll cool the house down too quickly. The whole principle behind air conditioning is to dehumidify, and then to cool. If we’re not dehumidifying, your house is going to be very damp. In that case the system cooled the air down too quickly, and we didn’t get enough of the water out. It’s almost going to feel like right before a rainstorm that really damp, really heavy air. That’s what it’s going to feel like inside your house and that’s really not that comfortable.

That too-quick cooling can cause a lot of mold issues too, because now all of the sudden the humidity level inside your house is 60%, 70%. Your carpets are damp, your walls are damp, all because you have a hot surface outside, and a cold damp surface inside. It’s going to cost moisture issues. Wherever there’s moisture, there’s a potential mold issue. You’ve got to be very careful when you’re sizing and really picking the right system for an air conditioning job.

Top 5 Reasons Not to DIY Your A/C

Do you know someone who bought an air conditioning system off the shelf and installed it themselves? It’s not a good idea.

  1. DIY voids ALL manufacturer’s warranties.
  2. Were all the proper permits pulled and was the system inspected?
  3. Who fixes it when it breaks down?
  4. Has it been properly vented?
  5. Is the associated electrical and plumbing up to code?

When you need a new A/C system, have your needs assessed by a professional, licensed, experienced HVAC contracting company who can then provide a safe, efficient new system.
