Called SR Gillis and Sons for a quote on a new A/C as the old one was giving up the ghost after 30 years. We also discussed a new furnace as the current one was 15 years old. Subsequent installation was smooth, on-time and with a lot of attention to detail and cleanliness.
The hot water heater installation was also done very professionally and I have found that the customer service SR Gillis provides is second to none. I would highly recommend their services.
