I have needed their services more than once to replace lights, a ceiling fan and also to install a new electrical box and breaker for our garbage disposal. Tyler promptly responded every time I called and he and Casey are both friendly, efficient and skillful. Aside from the excellent service, the qualities I appreciate the most is honesty for what work needs to be done and how Tyler is also very budget consciousness."

"It was a absolute pleasure working with the Wilson Brothers team from sales, site planning and install. The install and electrical teams were very professional and demonstrated in depth knowledge of the product and their craft. They arrived at the time specified and worked very neatly and in an organized fashion. We would absolutely recommend Wilson Brothers for any Heating/AC needs."
Three of the five heads are marked by the numbers in the blue circle. On the inside of the house is where you will find the mounted units. The slim ducts run alongside the white arrows and will eventually be covered to match the exterior of the house.
The slim ducts in the basement ceiling that connect from the branch box all the way to the 5 different heating and cooling units. These will be covered by the ceiling tiles once the job is finished.

"Heritage was amazing from start to finish! CJ talked us through everything while he was doing the estimate for us so we knew exactly what we would be getting and why and how the installation was going to go. He was also very quick to respond to our queries when we were making our decisions about who to go with for the install. Having the system installed just before the heat got intense was an unexpected bonus. The guys doing the install were very professional and knowledgeable as well. They stayed till the job was done and were very respectful of our time and our needs for the house during that time. The project took 2 and a half days from start to finish and we are super pleased with everything! The house feels so much cooler and less humid and we haven't even been using all of the units! A huge improvement!!!! Thank you so much! We will definitely recommend Heritage to friends in the area. Phenomenal service and phenomenal outcome!"

Generator Install questions, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window.
