What is an HVAC System Diagnostic?

 
An HVAC System Diagnostic is an important part of any HVAC service . Whether you need annual maintenance, A/C or Heating repair, and even replacing an air conditioner or furnace, We will need to check the entire system for anything that could lead to a potetial system failure.
 
For example, If we determine your blower motor has failed and needs to be replaced, Certainly replacing the motor will get your system heating or cooling again. But what caused the failure in the first place? Is the system too old? are there air restrictions which could cause the blower motor to fail? These questions could only be answered if we check complete HVAC system.

Technician not only replaced the thermostat but first checked my unit to make sure everything was working properly. He then made sure the installed thermostat was working properly as well and showed me how to use it. Would recommend highly

Where do I begin. Finding a new AC or heater repair company is like finding a new hairdresser or a auto repair company. It's terrifying. Years ago, I took a wild chance on Modern Air. First of all because it was a family-owned business and there's something I liked about that. I remember the first time that Charles from Modern Air came to my home because I had an air conditioning issue with my unit outside. He came over to me showing me a little fuse and said " see this little piece right here? Many people that can service your AC will tell you that you need a new unit or something major but this little piece cost $10 to replace". I knew I found my company. I have to call Modern Air at least once a year whether it's my old heater unit or my AC unit. They are extremely honest and although I am told ( and know) that my unit is ancient, they managed to keep it ticking for a few more years. . I live in the Westbury area and they will come all the way over to service my home from Katy. They show up on weekends if it's an emergency. Honestly I've never had to wait for days unless it was the part that was needed that out of stock at the moment.The issue is usually is taken care of within 2 days. I will leave you with this last sentence: When you find somebody that you can trust, you stick with them. You can trust Modern Air. 😊

Mr Charles Guthrie was the only person that answered my late night emergency call and showed up bright and early in the morning. Ended up having to replace my outside unit same day for a very reasonable price. I will not be using anyone else for my hvac needs! You can’t go wrong with Modern Air of Katy.
