Customer Reviews

Cory C.

The price and quality of service are outstanding. I’ve used them since moving to Lebanon with no problems. They always make time for their customers, but especially in emergencies.

Brad V.

We have used Henderson’s for years. The service and professionalism of the technicians are outstanding. Highly recommend them.

Eleanor R. S.

Complete and utter professionalism from beginning to end of the job. We just had them install a complete heating and air conditioning system (heat pump) including all ductwork and room registers. The crew was on the ball, polite, professional, and obviously knew their jobs from top to bottom. There was no wasted time, no fooling around, no confusion, minimal mess left behind. We have also had occasion to use them when systems in houses we rent needed service or repair and found a similar level of professionalism there as well. I really would recommend Henderson for all your heating and cooling needs.

Bonnie A.

They are absolutely knowledgeable of what they are doing. They are always very friendly when you call and respond quickly. You will never go wrong if you call them. They are the best I have ever dealt with. Prices are very very reasonable.

My parents had their air unit go out right as it started to get hot outside and Henderson’s was prompt and fast to get there get them a price and with very little time at all had them a brand new unit installed and could not be happier with the quality of work provided and the awesome customer support they offer highly recommend them for all your needs.
