I bought my house this year and called for duct cleaning. Duct cleaning guy showed me how bad my furnace is. Being first time homeowner, it was big project for me. I called multiple companies, but didn't get satisfactory response. Individual from AP heating was the first person, who listened my whole story and even visited my house same date. Estimates were given providing all details. Appointment was booked same time. Technicians showed up on the day of appointment and furnace was installed on same day. All safety was tested prior to leaving and since that day I don't have any issue at all. All documents and contact information is provided to me. Last important thing to mention, they saved me all water tank rental money. They explained to me how new water tank is energy efficient and how I will save money. I have installed new water tank last week.
