When your central heating and air conditioning system starts making tons of noise when it turns on and off this is time to call the local heating and air conditioning company.
Central heat and a/c units should not be making tons of noise when they come on and off.
When you do see this happening that means that there is most likely something going wrong with the motor or the fan that runs the thing. If you let it sit for too long without the help of a heating and air conditioning professional, it could lead to the complete breakdown of your central heating and air conditioning system unit. In turn, this could end up costing you thousands of dollars! But if you catch it right away the local heating and air conditioning company’s heating and cooling specialist can usually get it fixed right away and only cost you a few hundred bucks or so. While that is still a little bit of money, it is way better than having to invest thousands into a brand new, up to date, very expensive and very powerful central heating and air conditioning system unit. I learned this from when I had some noise issues with my central heating and cooling unit. Thankfully, I had enough sense to call the local heating and air conditioning company and the heat and a/c specialist told me that I did the right thing and what could have happened had I not called them for some serious HVAC repair on my central heat and a/c unit.
