I have been doing nanny work for this family for close to 2 years now, they were such a sweet family, a beautiful couple with 2 young children that I truly adored. We 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 recommended I come over and watch the kids as they were going on a weekend getaway for their anniversary, then at evening when we were having dinner, 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 particularly overheated evening. The kids were so scared all through the evening and I had to sleep in their room. The next day the cooling experts visited the residence and performed a heat pump service that revealed the cause of the hissing sound. It was a congested air conditioning filter. They updated it and proceeded to also check on the indoor air cleaning system. We had noticed the air quality had reduced and I recommended air purification help to which the air conditioning professional suggested the modern HVAC technology to incorporate with the quality air conditioning 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 corporation and the cooling and heating provider in case the family needed to update any HVAC gadget like the dial temperature control. At least the following evening we did not have to sleep with a hissing unit.
