"I called Carolina Energy Conservation to have some new insulation put in my attic. The estimater came out within a few days of the phone call, and I received a detailed e-mail about what to expect. Matt gave me a good run down of what I needed to make my upstairs floor more comfortable. He called ahead of time, was on time, and was very professional. The estimate was for 4,000 board ft of insulation, 800 sq ft of radiant barrier installed, and an attic tent/hatch. Total cost was about $1600. They asked for a down payment of 30% up front, which I paid. Matt told me I would recieve a call to schedule the work within 1-2 business days. That never happened. After 1 week I called and spoke with Mary, who informed me their office manager who does schedules was out sick the previous week. She assured me he would call me back to setup a time for the work to be done. That never happened either. Fast forward another week. I called a 2nd time, and finally got an apointment setup for the following week. The two guys they sent to do the job were friendly and professional. After a few hours they let me inspect the work, and it was completed to my satisfaction. I normally have to set my AC to 73-74 in the summer to keep my upstairs comfortable, and the HVAC turns on quite often. Now I can set it to 76-77 and it remains comfortable, and the HVAC doesn't run as often. All in all I am happy with the overall experience, guess they just got hung up on scheduling."

"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

Insulation FAQs, answered by experts

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.

Yes, brick houses are better insulated, because the bricks slow down the passage of air from the outside to the inside and vice-versa. This helps to stabilize the internal temperature of the home. When combined with proper residential insulation, brick houses are more efficient and better insulated than other types.

You can purchase bags of cellulose and loose-fill fiberglass blown-in insulation from the same local home improvement store where you rent your blower. If you want to use rock wool insulation, you may need to special order it.

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

Closed-cell foam may come with a higher price tag, but it’s worth the investment because of its strength and durability. This material offers excellent thermal and moisture resistance, contributing to its long life span. Its construction enhances energy efficiency, which can lead to reduced heating and cooling costs over time.
