The Benefits of Adding and Replacing Insulation

Insulation is often associated with winter, and for good reason: it helps keep you warm. But insulation isn’t just good for keeping your heat in; it is also important for keeping heat out during the summer. If you have poor insulation, you could be spending a lot of extra money cooling your home that could be recouped by adding to or replacing your current insulation in St. Augustine. Insulation is your first line of defense against cool air loss, so if you suspect your home may not be properly insulated, call J&W Heating and Air for an appointment.

How Does Insulation Help Keep You Cool?

The main job of insulation is to stop heat transfer. One of the basic laws of thermodynamics is that warm air will always travel to cool air. So, if you are cooling your home, one of the challenges you have is keeping the warm outdoor air from infiltrating your cool indoor air. Insulation helps by blocking the outdoor heat from coming into your home through the walls, ceilings and roof.

Different Kinds of Heat

There are 3 different kinds of heat transfer that insulation blocks: conduction, which is heat that moves through solids or liquids; convection, which moves through gases; and radiation, which is thermal heat. The way insulation works in the summer is not by keeping the cool air in, but by keeping the 3 kinds of heat out. In winter, insulation works to keep the heat in. This is why it’s important to have good insulation in your home.

Benefits of Insulation

  • Slows the transfer of heat
  • Prevents moisture exchange
  • Increases energy efficiency
  • Increases comfort levels

Recommended Thickness

Florida insulation recommendations are between R30 to R60 when there is no insulation, and R25 to R38 if you are adding insulation.

Just had an entirely new, full HVAC install done at our old house in Riverside, which was a fairly big job. Brian and... Will did the installation, and were awesome. There was going to be issues leveling the air handler in the attic, so they moved it to a new spot and hung it instead, getting new parts/changing the plan on the fly. We're much happier with this new setup and location of the air handler. I really appreciated this, their professionalism/thoroughness, and flexibility. Brian and Will worked super-hard, and double-checked everything once the job was done. Would use this company more

Two installers here early this morning. Worked all day. Very professional, extremely well mannered and quick to answer... all my questions. They are Dustin and Robert. Both men went above just installing my new unit, they were personable and knowledgeable in what they were doing. I was surprised when I found out these two hadn't been working that long together. They worked extremely well together. I highly recommend this two more

A snake crawled into my outdoor condenser and stopped my 16 year old Trane last week on Thursday. The power surge took... out my blower unit circuit board and the motor. I called J&W and Rob was over within two hours of my call. I was spec'd a new York 17 seer system and it was up and running on Monday. Technicians Jason and Brian arrived promptly and every facet of the installation was thorough. When completed, I would not of even known they were there except they left my garage cleaner! Thanks J&W!read more
