I scheduled a maintenance call for my A/C unit and furnace since it's been 15 years since I moved in and I read somewhere that you should have it looked at every other year, so I knew I was overdue. I called around and liked American HVAC because they picked up right away and scheduled me into a one hour time slot. I was rather pleasantly surprised when the technician showed up exactly on time and spent his time carefully inspecting the units and gave me some good options to either replace parts, replace the unit or just wait. I thought the advice was very fair and objective because he told me the risks and costs involved with each. I have already and would again recommend them just because of their honesty and transparency. You definitely don't get that with other companies.
