Since moving out from home, I have interacted with various cooling companys working on our unit, some good plus some bad.
I once had a cooling workman come to our condo after our heat pump started malfunctioning.
The a/c representative got to work performing the a/c service or so I thought. After some time, he stated that some components of the component were damaged plus so he needed the HVAC corporation to give new components. When I checked the components, they seemed fairly new, however since I was no a/c expert, I left him to his job however I made a note to take the components to another a/c worker or local company for a minute opinion. The company continued with the servicing, HVAC duct cleaning then he also upgraded the filter, however with a filter that was of a strange HVAC brand. I was not sure whether this would affect the function of the unit. The idea was working after the company left however not for long, the next afternoon, it broke down again so I called another company. It turns out that the first company had totally messed up our component by replacing the heat plus cooling system products with subfamiliar 1s. I ended up replacing the entire idea with a ductless HVAC, a fact that legitimately angered me, however fortunately, the new idea also came with an air quality idea to help with whole cabin air purification. Thankfully I got back our indoor comfort plus peace of mind however I l gained to ask for credentials for any company claiming to be an expert. It is also pressing to hire a company that is allied to a corporation for responsibility purposes.
