Should have called them first.
O'Callaghan is responsive, courteous, and competitively priced, and has an excellent service staff.
Wish we had used them to install our new furnace last year. We used Estes to install our new furnace and it was a train wreck.
Estes is all about the sales without the support; installation had issues, half hour waits on the phone with service, phone calls not returned. I called O'Callaghan and they were on the job pronto, and did a great job.
