"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."

"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

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Yes, installing an attic fan can help lower your electric bill—particularly if you live in a hot and humid region. By replacing hot and stuffy air with cooler air, these fans help regulate the temperature in your attic and the rest of your home, taking some of the pressure off of your air conditioner.

Provide utility bills and clear access to all areas of the home, including the attic and basement.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.
