There is quite a considerable gap between the majority of HVAC companies in terms of quality work. Instead of resolving the issue at its source, many contractors will use the easiest and least-effective solution possible, then walk away. Therefore, it's a matter of time before the original issue comes back, and you have to begin all over again.
We know that each of our clients has his or her unique situation. So, we don't perform any repairs until a professional technician identifies the root problem and determines if it needs to be corrected in the first place.
