The air conditioning system went down, and Abel On site was very fast to come and get a new system put in, as well as bring all the applicable documents to get the rebates that were available to use for efficiency. They were the original installers of the original Lennox system, making the equipment 46 years old before it stopped running. The fact that it had been running for so long and that they were able to service the equipment all these years is a tremendous reassurance to me. My mother is 86 years old, so she didn't need to have a house without air conditioning, and we were thrilled with longevity of the system she had. It should have crapped out 20 years ago! I can't say enough about Abel Onsite and what they have been able to do for us over the years.
