When first hiring a contractor for plumbing, HVAC, or any other service you may require, the first considerations are often price, expertise, or experience in the industry. These things are obviously critically important for success. However, when deciding to keep hiring the same contractor again and again, the ease of communication becomes a major factor.
For this reason, it is a good idea to work with a mechanical contractor that can handle HVAC and plumbing systems. Furthermore, at that single contractor, the ideal situation is that when you pick up the phone to report an issue or schedule an appointment, you have a single point of contact with whom you are familiar and can therefore trust.
The best example of this is the emergency situation we would all like to avoid. Maybe the heat shuts down in the middle of February, a pipe bursts due to the cold, or even both at the same time. In a situation like this, every minute counts. If you are able to call a single individual and have them respond with “we’ll be right over,” the stress of the situation can be partially mitigated at least.
