If you are consistently having to contact an Heating & Air Conditioning professional for constant repairs then it might be time to update your Heating & Air Conditioning installation.
It might be that your heating equipment is approaching the end of its lifespan especially if it is over thirteen years! No matter the number of times you have HVAC duct cleaning if it is the heating and cooling equipment that has a problem it will not be of much help; Duct cleaning only cleans the Heating & Air Conditioning duct and the other conduits however will not do much for equipment if it is beyond repair. Last week I visited the dentist and came across the Heating & Air Conditioning provider truck in the parking lot. The Heating & Air Conditioning tech had come to update the existing idea with a new Heating & Air Conditioning zone control system. They had also invested in air quality systems. They have an air purification idea which at first I thought was an air purification system however it turns out it was an air scrubber. This would explain the high air quality in the clinic. The temperature control of the seasoned idea was more on the cool side however it was never uncomfortable, but on the multiple chances I had brought her here, our niece complained that it was too cold but I attributed it to nerves since the indoor environment never bothered myself and others and I had been there multiple times. I also noticed that it was the same homeowner solutions dealer that had done our heat pump maintenance last month. Their repairmen were particularly professional and particularly good at their work. I do not suppose of a single person that sought their services and had complaints about their work.
