Your HVAC system ran into a gridlock and is in need of immediate servicing. If you’re not savvy enough yet to size up the kind of repairman you need for the job, before, there’s the possibility that you’ll come across a shady contractor who is looking out to take advantage of clueless customer. Wise up and arm yourself with some hiring smarts and know how to spot the shifty service technicians.
Making price quotes for system installations or major repair work on the phone.
Trust it when you’re told that no reputable contractor will give out a price estimate until the system in question is personally checked out by the company’s technicians. If the contractor you’re currently negotiating with does the same exact thing, release him without question.
Pricing that’s too good to be true.
Identifying this is easy if you already have a pre-determined list of HVAC contractors with their estimated pricing clearly indicated. If the repair rates are too low compared to those on your list, don’t risk it. HVAC repairs are very delicate jobs and cheap costs here often mean sub-standard workmanship. There is also a chance that this contractor is planning to unreasonably spike the bill up midway through the job with numerous hidden fees; notwithstanding using cheap or counterfeit parts which can further damage your system.
Rules by thumb.
Contractors which skip formal equipment sizing are just plain lazy. Instead of using recognized measurement methods, they only guess. Avoid them before it’s too late to back out.
