I have been doing nanny work for this family for close to more than one years now! They were such a sweet family, an appealing couple with 2 kids that I absolutely adored. The two of us would play so many games with them and even visit the park. I was so worn out from playing at the end of each day. I loved the energy they had, but at times I could not keep up with them. Last week, the couple had advocated I come over and watch the kids as they were going on a weekend getaway for their anniversary. At night when we were having breakfast, we heard a loud shuffling noise followed by a hissing sound. It was their heat pump, I could not switch it off because it was a recognizably sizzling night. The kids were so scared all through the night and I had to sleep in their room. The next day the cooling experts visited the residence and performed a heat pump maintenance that revealed the cause of the hissing sound. It was a blocked air conditioner filter. They changed it and proceeded to also check on the indoor air cleaning system. We had noticed the air quality had reduced and I advocated air purification help to which the air conditioner professional suggested the modern HVAC technology to incorporate with the quality a/c for maximum service. The servicemans left a booklet with all the necessary details on a/c care right from the a/c set up. They also left contacts for the home comfort company and the cooling and heating provider in case the family needed to substitute any heating and air conditioning gadget like the dial control unit. At least the following night we did not have to sleep with a hissing unit.
