We hired A Plus to replace a furnace blower motor, and we have regretted it ever since.
First, they installed the wrong blower motor, one that is not compatible with our furnace (even thought I had pointed out to the tech that the specs of the new motor do not match the exact specs listed on our original motor).
After installation, the incompatible blower was making a very loud noise that can be heard throughout all the vents in the house. The tech 'diagnosed' the cause of the sound, as well as the smell coming from the new motor.
His diagnosis: 1) The control board is faulty resulting in incorrect motor speed and the loud noise. Cost to replace ~$500+
2) The new motor smell was caused by a cracked heat exchanger releasing carbon dioxide through the vents - Cost to replace - $1000+
Then he tried to convince us that we'd be better off buying a new furnace for $4000+tax. He even contacted another technician from the company to come out who confirmed his diagnosis and recommendation. We later found out that both diagnosis were incorrect as the real reason for the problem was the incompatible blower motor that they installed.
Having one tech make a mistake is one thing, but two from the same company indicates that the company hires inexperienced technicians or that they have a mandate to try to sell new furnaces by misleading customers. I'm grateful that we decided to get a 2nd opinion from a different HVAC company or else we would have lost thousands of $$ on parts we did not need, on top of the $500 we wasted on the incompatible motor they installed.
After the 2nd HVAC company replaced the incompatible motor with the correct motor, the furnace was operating perfectly. When we explained how the incompatible motor needed to be replaced to Jack, the branch manager of A Plus, he refused to acknowledge their own mistake and claimed that the other company is not telling the truth and just trying to sell us a new motor. He refused to take back the useless blower motor that they installed less than a week earlier and would not refund our money.
If inexperienced, untrustworthy, rude, and unprofessional is what you are looking for, then A plus is the company to call.
