Hvac Repair reviews in South Charleston

    They were very prompt and kept me informed as they diagnosed the problem and checked the availability of parts. It was a cold day and I had 2 week old baby so I appreciated the technician's efforts to get our heat back on quickly. He stayed late in order to make sure we had heat that night. We will definitely call Sig Cox again when we have a problem with our heat or air.

    The process was completed in two weeks and some minor adjustments the next week and we were up and running.  I would recommend them to anyone.  This was a huge job, i talked to 3 contractors and Delong was by far the most professional and responsive to my questions.  I started the process a year ago and asked a lot of questions and Ted and his crew were willing to answer all of them so that i knew what i was getting into.  I am appreciative of the level of integrity and trust they displayed throughout the process, they basically lived at my house for 2 weeks. 
    First Week:
      - remove old furnaces
      - remove old air conditioners
      - remove drain lines etc
      - rewire electric for the furnaces
      - install new exhaust
      - alot of prep work i cannot list
    Second Week:
      - install new geo's
      - install new furnaces (backup propane)
      - retrofit duct work on the units to connect to my existing duct work
      - install the ground loop in the yard (i went with trench vs directional boring for two reasons, cost and i have the space to dig it in.
      - connect loop to the geothermal untis
      - fill the geo system with fluid and test for leaks and remove air from lines
      - start them up and make sure everything is running fine.
    Third Week:
      - units shut off a few times so it needed adjustments so they sent a tech out the next morning and corrected the programming
      - made another trip out to adjust the settings
      - after a week of running did a final inspection and finished
    I am surprised after all the work that as needed to retrofit a system like this in an old farmhouse they only had to make 2 service calls to get it tuned in, the calls were free as part if the install and i was impressed it only took two they really know what they are doing.

    Appointment was at 3:00, office called & sad was running 10-15 min late. 1st time anyone called & said be 15 min late. Everything about DeLong is A+. Had a great time talking to Don about being a Chevy & Nascar fan. All A/C & heating work will go to DeLong in future.

    We use DeLong as our heating service all the time. 

    They installed a new boiler and did an annual check of the equipment.  (We purchased a service contract- which is very reasonable.)  Overall, we have been very satisfied with their service.

    I called DeLong's on a Friday evening at approximately 9:15. I immediately received a call back and a service man was here within a half hour. He was such a nice man with great knowledge of geothermal. He replaced the molon and we had heat within 2.5 hours. I would absolutely use them again in the future!
