HVAC Repairs

There’s not a lot worse than a southern summer day without AC, or coming home to a cold house in the winter! It may not just be a coincidence that your AC goes out on the hottest days and your heat goes out on the coldest. 

The reason RSI Carolina offers the best service in the Upstate is that unlike many other companies, our service techs are non-commissioned. This means our techs are not going to sell you anything that isn't required for a repair.

It has been proven that adequate insulation is required to keep a home comfortable at an economical price.  If you own an older home, chances are your insulation in your attic is minimal and the flooring insulation usually is non existent.  In these situations, your heating and cooling are leaving through the attic and your power bill is very high. Insulating your home will increase your Heating and Air conditioning performance and lower utility bills are to be expected.

When the time comes to replace your old inefficient Heating and Air Conditioning system, have your Home Energy Expert from RSI Carolina show you the difference in a system required to keep a house comfortable with existing insulation, verses a smaller system maintaining the same desired home comfort, because you made the smart, economical choice to have insulation added. 

Already had your HVAC system replaced but still want to learn more about insulating?  No problem, contact RSI Carolina to set up a free in-home consultation with one of our Home Energy Experts, and see how RSI Carolina can help you make a smart investment into Insulating and start lowering those unwanted utility bills!
