I am so thankful that Eddington Heating and Cooling chose to retire and sell their Customers Accounts to CJS Heating and Air. I trusted Eddington 100% and now I trust their choice CJS to service my Heating and Air needs. Kevin our initial tech, I called him Mr. Wonderful for a reason. He is beyond educated and made my concerns a PRIORITY. Kevin asked me tons of questions and he listened to me. Literally 24 HOURS after I MET KEVIN my brand new system was installed and operating at 100% efficiency. That's the exact kind of service that I needed. The Installation team members were meticulous, timely, personable, and provided great communication plus education. My CJS team are 3 great men and Technicians. I wish my equipment didn't require a complete replacement but.... it did and I seen the problems with my own eyes. Thank You CJS and Team! You are Stellar!

CJS was the best! I had issues with my A/C, and Kyle conducted a very extensive diagnosis of my entire system and recommended a very reasonable repair solution. The last two companies tried to sell me an entire new system. CJS is highly professional and trustworthy. They are now my HVAC company for life.

Justin, a project manager for CJS, conducted a detailed technical review of our home and provided a range of heating and air conditioning options based upon our needs. Once agreed, CJS sent Ryan and Gabe to install the equipment. The job was difficult given very limited space to replace the 2nd floor furnace/ac coil and an unexpected addition (at my request) to replace the 1st floor coil. Outdoors, a pad was constructed to set the ac compressor on for the 1st floor unit. This job was made difficult given the steep grade and conditions that were rainy/muddy. Ryan and Gabe handled everything like pros. My wife and I appreciated their attention to the condition of our home protecting the floors with plastic covers for their shoes, setting up drop cloths everywhere and plastic wrap to protect carpets. We are very satisfied with the quality of service and the equipment installed. We look forward to years of worry-free operation that is covered by a 10-year parts and labor warranty. Thank you CJS for a job well done!

It went excellent. Ryan is very professional and knowledgeable of the boiler system. Keep us informed every step of the way. The boiler had not been cleaned in several years and needed to be done manually. Clean up was great. Look forward to him returning to do additional work.

Alex and Ryan arrived ahead of time and were very professional. Each wore a mask, booties over their shoes to protect floors and laid down pads to cover floor. They removed the old unit and installed a new 50 gallon water heater in no time. Will use again for HVAC service in the near future.

Excellent. CJ saved us 8yrs ago. They were the ONLY Service provider who provided emergency service appointments when heat failed in winter. Other companies (including our home warranty provider) wanted us to wait a few days before coming out. CJS got our heat going again with a little oil and expert knowledge. Yes, a part was needed to be replaced, but in the meantime we had heat. As the years have passed, we have CJS service our units in spring and fall ahead of heat and cooling seasons. 4yrs ago, we replaced the 10yr old furnace. They said we could save $ if we did the AC at the same time. We declined. Oops! Less than 1yr later, the AC quit. We should have listened to the professionals. Today, after 4yrs with the new units, the AC stopped working. They didn’t have appointment available for 3 days. Yikes!!! I explained that I have been a loyal customer. They found a technician and sent him over today!!! The AC got fixed today. Under warranty, so no fee. I am still under service contract with CJS, so no diagnosis visit fee either. $0 today. Loyalty pays. Thanks CJS!!!

Good 410a refrigerant was a little high so they removed some seems to be running good now.

Still a work in progress. I’m sure my old house is giving him head aches but the team is pushing on and getting the job done. Day two down and two to go.
