I have been a 25 year customer with Weathermakers/Kearney & Sons. I have the annual maintenance plan on both my homes, a total of 3 systems. In these years they have completely replaced the Heating /AC one system and A/C systems in the other two, and replaced 2 water heaters. With the maintenance plan comes no extra charge for call outs nights and weekends. There have been a few repair callouts (the dreaded air conditioner capacitor failure) and they have always promptly restored service.
Great, friendly technicians who take the time to explain what they are doing, or what needs to be done.
Peace of mind in knowing your system is regularly inspected, cleaned, and tested.
So yes, I am a loyal customer who will be with them for the next 20 years and beyond.
Eventually a system will fail and need replacement. I already have a credit of $300 in my Loyalty account toward the next system replacement. Whenever that occurs, it will help reduce the replacement cost.
So this is a review from a thoroughly happy customer.
