"I had a problem room that had little insulation. Cold in the winter. Hot in the summer. No attic access. Energy services group was able to drill large holes in the ceiling & outside wall and spray in insulation. Then plug the holes and spackle. Replaced canister lights with led ones. They explained to my wife what they were going to do before it happened. Then said what they actually were able to accomplish. Great communication. Quick to schedule. Cleaned up after themselves. A quality company"

"Ed Burke was extremely professional, thorough and insightful both in his assessment of a difficult and complex situation we had in our attic and also throughout the insulation removal and installation process.  He provided solutions that significantly improved the energy efficiency in our attic and also was very helpful in troubleshooting and making good referrals so that our attic ventilation system could function optimally.  His installation and removal crew were also professional, hard working and responsive to questions throughout the process including explaining thoroughly to us what would happen in terms of the set-up to do the work so we would be prepared and all the way through completion, including a a thorough clean up.  We would highly recommend Ed and his team!

"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

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.

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.

An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.
