Do not use AAA Heating & Air Conditioning. They lie.
Everyone in the company led us to believe that the whole job (new furnace and duct work) would take 2-3 days. There was no mention of the gas line installation, which took 4 months, or the days and days of inspection and testing that follows the installation. On top of that, the 2-3 day install took 5 days (that's before the testing and troubleshooting and inspections) and we only got that after 4 cancelled appointments over the course of two months.
When the installation was done, the house was cold. The installer told me it would just take a couple of days for the house to heat up. After a week, he returned and discovered that his partner had left out a section of duct 10 feet long. I had been heating my crawlspace for a week!
Throughout the course of the job, everything the owner of the company, Victor, told me was not true: the time frames, excuses, promises.
Now that the job really is finished, it turns out that the chimney they installed through the roof leaks.
