We had a problem with our furnace being off when we returned home from a trip. I called Gary's Plumbing and Heating, LLC in the evening and they returned my call the next morning. They sent a technician to us 30 minutes later. He found that our furnace was 15 years old and we could either repair or replace it. I had them replace the entire furnace and the job was completed that same day. The system has worked fine since then and we're very pleased with the quick response time.
