The HVAC Service

I enjoyed my experience with The HVAC service. The technician called us 30 minutes before his arrival, so there was no need for us to stay in the apartment the whole day and wait. Last week we noticed that our boiler started losing pressure. Firstly, we decided to repressurize the system ourselves, but it would continue consistently losing pressure. So we called the HVAC service. The technician Chris arrived the next morning after we called and carefully inspected every part of the boiler. He seemed greatly trained and explained to us that the radiators needed balancing (I am not sure what exactly it means, but the boiler is running flawlessly again). Thanx!
