Get matched with top home energy auditors in Lancaster, PA

"I highly recommend this business. I recently moved to the Lancaster area after purchasing a house that was built in the early 50s which needs some overdue maintenance. The attic insulation was old, worn out, and installed incorrectly. King Conservation gave me an estimate I was happy with and I agreed to having them do the work. They came in and air sealed the attic, removed the old insulation that was not needed, then installed new insulation properly. The team that came in were very professional and did a great work. I am very happy with the difference it made with the warmth in my house. I will definitely have them back to work on my basement insulation. 5 Stars!! Thank you Casey and the rest of the crew."

"They were professional, and they did a very well job."

"Couldn't have gone smoother. Workers had attic entrance contained and sealed off, wore their masks entire time, put down drop cloth to enter the home and cleaned up once completed. We were provided images of the attic completely cleaned and sanitized, and then images of new insulation added."

"As always the technician was on time, personable, professional, competent, and did an excellent job. I have been a customer of J.K. Mechanical since 1988 and was never disappointed with their service."

"Great job!"

"I AM LIVID WITH THEIR SERVICE. My husband and I have been living in our home 4 years without a single issue with our cooling system. We had UGI come out to "service" our system and said everything looked great....2 months later something with our compressor blew...that was $400. Then this morning, less than 30 days later, we apparently needed a brand new thermostat.....another $400 and guess what? MY HOUSE IS STILL NOT COOLING DOWN. So I called and said how it is absolutely ridiculous that there is still an issue especially after charging us to "fix" the thermostat. I am obviously frustrated. I work from home, its hot and I am pregnant with 4 pets in my home that are distressed from the rising heat and their customer service agent has the audacity to be BEYOND RUDE and tell me "to have a better day" as if it was MY FAULT...ok. It is very odd that ever since they came to "service" our central air system they've had to come back THREE TIMES and the system STILL NOT WORK. BEWARE!"

"Very good Recommend them"

""My family and I enjoyed a very positive experience with the Quality Degree team regarding the installation of two new HVAC systems. I was very impressed with the high degree of thoroughness and professionalism shown by Comfort Advisor, Erica Zecca. From the start, Erica made us feel confident and assured in moving forward with Quality Degree, and we were delighted that her estimate was very competitive. The installation team included Ken, Tarik, AJ, Angel, and Daniel. They arrived on time and immediately went to work on the replacement and installation. Throughout the entire process, they were very efficient, communicative, and neat. Ken was diligent in reviewing the new components and their maintenance, and he stated we should call Quality Degree anytime if we have any questions. In sum, Quality Degree delivered outstanding service with a high degree of professionalism and attention to detail. Their superb ratings online are truly accurate and well-deserved, and I am delighted to contribute to the same. Any homeowners needing one or more of the wide variety of services Quality Degree provides should contact them and enjoy the certainty of receiving premier, high-value service.""

"He did a great job. Very professional and an exceptionally detailed result with infrared photos and explanations. I was able to to fix all of the areas where the heat was going out/cold air coming in."

"I supposedly won their contest at the State College Home Show 2022 for $1200 certificate. Rep came out and knew nothing about giving me the prize I won. Should have seen this as red flag. Window and entry door replaced anyway. Like the window. BUT, the door has major air draft coming in down the side and across the bottom. Have been calling repeatedly for 2 months leaving multiple messages- no return call since back in October. Company sent me letter 11/30 and called me that evening trying to get me to hire them to do more work. Assured me they would send someone to correct problem with initial work. Still have not received phone call or service visit from anyone in this company. Don't enter their contests at Home shows- I think they use this as way to get into your home to sell you their company when you haven't really won anything. and don't hire them to do any work. They will not fix any problems!!"
