This summer time I had an incident with our system. I woke up a single morning to find the condo cold, though it was extremely boiling outside, the cold un-even temperatures inside were not welcomed. Everything in moderation, right? Even moderation. So I went up to the attic to check on the ductless Heating, Ventilation, plus A/C. The floor was all wet plus the machine was making unofficial noises. I was sure there was no concernshooting I would do to improve the situation so I contacted an air conditioning expert to check on the system, but just a handful of weeks back, I made sure to perform air conditioning service as I prepared for summer time so I did not understand why the machine was now having complications. The cooling system worker confirmed that the heat plus air conditioning system products were not worn out however the refrigerant was leaking plus so the machine was straining to supply the desired un-even temperatures hence the noise. The cooling system representative recommended also considering installing an air quality system to help with whole condo air purification. He also recommended I try the Heating, Ventilation, plus A/C company where I could get a variety of Heating, Ventilation, plus A/C brands to choose from. I was lucky I did not have to substitute our unit, but, it was not the case with our friend. Her machine broke down about two weeks into summer time plus the cooling workman had recommended she substitute her unit. She opted for a heat pump which is genuinely efficient. The local business did the upgrade. Though she had to deal with constant air duct cleaning, she was fine having a new system. It is important you ensure to service your machine at least once a year as this prolongs the life of the machine plus saves you constant repairs plus service costs.
