I have used Oliver since 1978. They do great work and are always respectful to me and my family. All companies should hope to treat their customers half as good as the way Oliver has treated us. Dolores G. Media, PA>

I have had a service contract with Oliver for several years, they have cleaned & maintained by heater & air conditioner without a problem. This year I have had several issues with my heater, they responded quickly, the mechanics are always polite and they put shoe covers on their work boots to protect your carpet.

Back in the summer, they were very quick to respond to my air conditioning need especially when other vendors were putting me off. They fixed it and put me on a plan that was very affordable. I just got finished calling them to schedule my heating unit. I've cancelled doing business with all other HVAC companies. Nice job!

I was rather unimpressed with this company, they were late to my appointment and they were the highest price of the 3 that I consulted.

Good feeling to know that gentlemen be available in emergency's and routine check ups.
