Description of Work: Heating and AC

Great service! When we moved into our home we knew the AC and furnace were going to need to be replaced. After a year of the house being hot on one side and cold on the other we got some quotes to replace everything. McLay was not only the best price but I felt was also the most knowledgeable. They replaced everything and the house is much more comfortable now.

Description of Work: Water heater was not working!

Only good things to say about McLay Services! From scheduling the services call to getting the work done. The technician was up front with pricing and told me only what needed to be repaired on my water heater. He even did a free safety check on my furnace and found a dirty air filter that needed replacement. I will be calling again in the future.

Description of Work: Ac and furnace installation

They were very professional, on time, took the amount of time they said it would, and cleaned up afterwards. The ac is great
