Get matched with top nest installation pros in Littlestown, PA

"Bought security through ADT mainly for the automation options that come with the system. My spouse loves being able to turn on and off our lights in different areas of the house while we are gone. We travel often, so giving the illusion that we are home is a good deterrent."

"We had an outstanding experience with Holtzople Heating, Air Conditioning & Electrical Services thanks to the excellent work of Andrew and Jake. From the moment they arrived, they were professional, courteous, and clearly very knowledgeable. Andrew and Jake took the time to explain everything they were doing, answered all of our questions patiently, and worked efficiently to get the job done right. Their attention to detail and commitment to quality were obvious throughout the entire process. Our installation was seamless and we are very pleased. It’s not every day you find staff who combine technical skill with great customer service, but these two really delivered. It’s clear that Holtzople hires top-notch staff, and I wouldn’t hesitate to recommend their services to anyone. In fact, we are now repeat customers and have used Holtzople for additional services. Thanks again to Andrew and Jake for a job well done, and Holtzople for providing excellent products and services!"

"All work was excellent, from the initial meeting to diagnose the problem and work to be done, to the work itself: removal of the old-and-failing heat pump, installation of the new Bosch heat pump. The crew (Kahlil Hunter and his apprentice) were efficient, professional, tidy, and pleasant. And everything's working fine now!"

"Great crew. Responded quickly and professionally. Was able to circumvent some issues with my initial wants and come up with a better layout for the project. Just what was needed and complete in record time. Great pricing as well for the detailed work performed."

"GREAT!!!!!! Excellent service, very professional, on time and honest!!! I will be using their service again."

"We bought a new construction and McCrea installed the HVAC. Home inspection identified the heat pump was not working in Oct. 2020. McCrea identified it was due to leaking refrigerants and promise fixed the issue. Our electric bill was extremely high the following two months and the heat pump was not cooling in Spring 2021. McCrea sent technician and again repaired the system. Bought their maintenance plan. We had 4+ repairs plus regular tune up in the past two years. Last week the heat pump stopped cooling again. We are out of labor warranty and charge us with $89 diagnostic cost after membership discount. It took three days for them to send someone to check while we suffering 90F in our house. They identified the compressor dead and need replacement. They charge $1900 for labor after membership discount. Most likely cause of the compressor failure is "suicide" with assistance. Low refrigerant at beginning and over change in later repairs likely contributed the short life."

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

"I have been a Guardian customer for almost 10 years. I have their system on both of my properties. I had not had any issues with Guardian until recently. My doorbell/camera have been out of commission since 5/8/2025. I have been waiting for a Guardian subcontractor to come out to repair/replace since 5/8/2025. I find it hard to believe that this large, nationwide security company does not have inhouse techs for situations like this or cannot find a certified contractor. I am so frustrated. And if I cancel my contract (because their equipment is not functioning) I have to payout the balance of the contract,"

"We hired Martin Networking to install surveillance in our retail space. Jesse was professional and knowledgeable the entire way through the process. Prompt to our consultation, experienced with offering recommendations on placement of cameras and different styles available to give us the coverage we needed. The install was handled flawlessly. He was respectful of our space and kept all wiring concealed for a clean finish. After the install was complete, he made sure to follow up with a thorough explanation of the features of the cameras we selected and made sure we were comfortable accessing the app and adjusting settings to fit our needs. An additional trip was made for a minor adjustment on the angle of one camera and we have been very pleased with the performance of what was installed. So satisfied with service and product, we are having cameras installed at our home next. "

"Our whole furnace broke and in within 48 hours we had a brand new one for a great price and ready to go before the winter. They worked quickly and efficiently especially with me having a little one running around. I would highly recommend them to anyone. Having a huge appliance break right before the cold weather comes was stressful and they did their best to make sure we didn't go without heat in our old house. Thank you for taking care of us and 5 stars hands down !"
