"I want to thank Hosack Plumbing, and Kent, for getting my situation cleaned up quickly and professionally. My water heater install is perfect, my water pressure spot on thanks to the new PRV, and is ready for inspection. Kent was thorough, professional, and very clean. He noticed my mask when I answered the door and wore a kn95 mask the whole time. The life coaching advice was an added bonus. Kent's work was great and I'm very pleased with the service provided."

"Fantastic experience with Paul, Mindy and their team when they helped us insulate the attic spaces surrounding and above our 1.5 story house. We have immediately seen the benefit from the insulation through our energy consumption, reducing the run-time of our unit by ~4 hours a day on like-weather days. This team will take care of your exact needs by tailoring their solutions to your specific situation and they don't cut any corners in ensuring your getting the value deserved!"

"The boiler was fairly new, but had never been serviced. The workman came on Saturday in response to an emergency call, and fixed the boiler as well as performed basic maintenance which badly needed to be done. He didn't bleed the radiators, so I will be contacting the company to make arrangements to have that techs do this as well. I would consider relying on Vitt's for routine maintenance of our heating system, as well as replacement of our water heater."

"We called for a quote and Mindy came the same day to review our spaces and provide a price. After rain cancelled our first installation, the second date was dry and the team of three guys were on time. They reviewed where we wanted the tubes and took their time with the installation. The addition of natural light makes a huge difference and we are very satisfied with the product and the installation."

Energy Efficiency Auditing FAQs, answered by experts

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.

The extra insulation helps reduce energy costs by minimizing drafts and temperature exchange between indoors and outdoors.
