If you are looking to hire a heating and air conditioning contractor instead of a local heat and a/c company there is one important thing you need to know and check on.
And that is if the independent heating and air conditioning contractor has a certification.
There are a lot of heat and a/c contractors out there that do not have a certification. Which in some cases you would never know because they are HVAC professionals that just did not go to school and are really good! But in the event something went wrong in their fixing or installing a heating and cooling system, if they do not have a certification you will not be protected by law and will be stuck with the loss of having to invest in a brand new central heating and cooling unit and there is nothing you could do about it. However, if they are legit certified heating and air conditioning specialists, they usually come with some kind of insurance in the event something like that happens. Any legit heating and air conditioning contractor will not be insulted if you ask to see their certification. If they give any kind of notion that they do not want to show it to you or get mad at you for asking, right away you will want to avoid that independent heating and air conditioning contractor because that means for sure that they are not legal, legit and most certainly not certified at all. I hope this tip helps in your shopping around for an independent heating and air conditioning contractor!
