Holley Heating and Air, was a nightmare! They installed a propane furnace for me. Holley said the installation would take 2-3 days. It took 4 months!! When the installation started they installed the wrong and a less expensive furnace. I caught this mistake. They also installed the wrong thermostat, also a less expensive one. I caught this as well. At first I thought this was a mistake. I'm not so sure now. If it was a mistake, it shows the incompetence of the company. Holley said that the job would be turn-key, and all materials and trash would be removed. They left behind piles of trash, PVC pipes in my carport, foam insulation running down my foundation, rolls of tape and strapping. They even left the thermostat that they put on the first time. I sent Holley and email about the above items, no action was taken. If you are looking for a quality heating and air company, one who is customer oriented and performs quality workmanship. Stay away from Holley Heating and Air.
