"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"

"Highly recommended. A very professional and effective team!!! Brittan Built was the lead in a Home Energy Star project for our house. Dan Brittin is extremely knowledgable in all aspects of home energy efficiency processes, equipment, and installation as well as the mechanics of the industry at both the commercial and governmental levels. Dan's team did a thorough and efficient job in the insulation project which included the attic, attic stairs replacement, garage, and dryer venting. The on site team were friendly, knowledgable, and kept me informed every step of the way. Could not be more satisfied with the work and the significant improvement in temperature consistency throughout our house, especially between the first and second floors. This project also included a high efficiency water heater installation. While Brittin Built had several installer options, I was able to use my preferred provider who worked directly with Brittan Built so the entire project was seamless. Thank you so much!!!"

"Since that time, I have not  experienced any problems with the heater.  I would have no problem referring this company or the service representative to my friends.  It's not often a consumer finds decent, honest contractors who will stand behind their work.  Thank you for the referral."

"Ira was cordial and professional. He has practical experience and knowledge of residential energy audits. He was able to provide useful suggestions but not definitive solutions to issues. That may have been due to inaccessible interior walls. I am frustrated that a full written report that had been promised still has not been produced six weeks later."

"Person who visited was very polite and noted that what I purchased was likely not something that would meet my expectations.  I wanted an energy audit, how my systems could be improved in home, lighting, heating, insulation and air conditioners.  What I got was a list of things they could work on and the price to do that work.  The work list in no way was considered an energy audit, rather it was a punch list of things I could do based on their visual inspection.  I did not have a comparison of work and benefit/savings calculation.  There was no checklist of inefficiencies and how that translated into energy losses. For example, multiple hi hat lights in house, they spoke about boxing and insulating a few, less than 10, when I have almost 90 in house.  Overall I was disappointed, the tech who came said the offering needed to be better presented prior to start of work."

"Upon calling RC with my problem, (which was fading hot water temps.) They were professional in diagnosis and service and product options.  The estimate provided was the best price I had received from other competitors.
We arranged a service date.  The repair man was not only quick and efficient, but very informative of how to care and maintain my new unit.  He even gave me pointers on other home heating and air equipment in my home.  
The resulting impression was that when I have another heating, air condition, ventilation issues, I will turn to RC for reliable service.

Energy Efficiency Auditing FAQs, answered by experts

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.
