FYI BEWARE!!! Many local, small & large so-called reputable contractors are NOT pulling your required permits & getting the mandatory inspections completed on the MD air conditioners, heat pumps, gas fireplaces, standby generators or water heaters they install!

Here is what I would want to know if I was considering a new AC heat pump, air conditioner, gas fireplace or water heater installation in MD. First, it takes A LOT of time, money, staff, expertise & licensing to go through the permitting & then through the rough-in & final inspection processes.

Do I need a MD permit & inspection for my new heat pump, AC, gas logs, standby generator or water heater replacement or installation? In most cases YES, YOU DO need permits & inspections.

What could happen if your AC, furnace, gas fireplace, standby generator or water heater contractor does NOT pull your required permits and even more importantly they don't have your work inspected & passed?

If problems with your home should arise requiring you to file a home owner's insurance claim due to your illegally installed; heat pump, AC, gas fireplace, standby generator or water heater, your home owner's insurance will probably deny all of your insurance claims!

so if you have to sell your home in the future, you will probably have to pay & get the illegal work inspected & able to pass current codes at the time of the sale. Belair Engineering will pull ALL your required MD permits & pass/stand ALL your inspections!
