Great customer service. Worked to find the part needed quickly and was able to come install the following day! We had been without heat for 5 days and Mike was a lifesaver getting us the part and coming out to install. His communication with us was superb. Would hire him again!

Doorbell Installation questions, answered by experts

Insulating your ducts offers several benefits, including:

Improved energy efficiency: Duct insulation prevents energy losses, reducing heating and cooling costs.
Cost savings: Lower energy bills make insulation a cost-effective investment.
Environmental benefits: Enhanced efficiency reduces your carbon footprint.
Consistent comfort: Insulated ducts help maintain a stable indoor temperature.
Better indoor air quality: Reduced allergens and pollutants improve air quality.

Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into spray foam insulation or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.

Costs depend on area size, material thickness, and site preparation needs.

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.
