"Tom is an expert in this field. He is a wealth of information during the energy audit. He is complete and takes the time to ensure he is measuring things correctly and most importantly to answer any questions so you understand. You need to try this service if you live in an older house. Our house was like night and day after the insulation work in walls, floors, and some ceilings. The house was easier to heat. An added bonus was how quiet it became. Tom will come back in the spring for another energy audit after we finish some final work. This will find any gaps and help prove the benefits we have already seen. Tom came back and did a post review to confirm the steps and work. While we saw and felt results, the technical results were amazing. What great follow through by a contractor! I have hired him for again for additional work as he does other home efficiency recommendations and work besides insulation. Highly recommend using and taking his advice."

"I?ve had them since I moved in here for my air conditioning and heating system. I?ve been here for 2 ? years. The only problem was them diagnosing the exact problem, it took them 4 or 5 times that they came out before they figured out what was wrong. I have a contract with them, so it basically didn?t cost me anything even if they came 10 times. They came right away and they were concerned about trying to figure out what was wrong. It was an intermittent problem, so that was the reason they couldn?t figure it out completely. With the service contract, it didn?t really cost me anything more."

"Very good, almost great. The install team arrived on time, confirmed work order & started the job. In about 4.5 hrs, power was applied & we started to get heat. A quick overview of the HAVC system was given, balance paid all questions answered and there were smiles on most faces. The sales person described the operation of the new HAVC to be quieter than current system and it is. However, the term quieter was not expressed in db difference so a service tech came out and was able to discuss the issue. The whole evolution was a positive event and we will gladly refer Orbit Energy & Power LLC, as a HAVC company that I will work with again."

Energy Efficiency Auditing FAQs, answered by experts

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.
