When our sister came to visit last fall, she pointed out something about our condo that I had noticed in the 3 months that I had lived in the house. My sister was sleeping in the guest study room at the far end of the hallway on the first floor of the house. She was complaining that she had a long night because the guest room was particularly cold and the bathroom was even colder. After furnishing the guest room, I never went in there and that’s why I never knew the issue. Being an Heating & Air Conditioning professional, our sister explained that I needed an Heating & Air Conditioning zone control unit. Since it was fall and our dust sensitivities were acting up, she added that an air purification idea would help ease up the dust sensitivities when I was in the house. The people I was with and I called up the local Heating & Air Conditioning provider and ordered an air quality system. These units would help to wash out the air and enhance the air quality within the house. After the Heating & Air Conditioning installation was done, I noticed a severe improvement in the temperature in the guest study room and bathroom. These new systems allowed myself and others to use temperature control and set varying temperatures for the top and bottom floors. The Heating & Air Conditioning tech, upon noticing our endless sneezing, suggested that I invest in scheduling quality HVAC duct cleaning services. This process included duct cleaning the Heating & Air Conditioning ducts plus some of the components of the unit. To keep everything in check, I tied up annual tune-ups for our equipment with the homeowner solutions dealer downtown. The rest of the visit from our sister went well and it was a lot of fun. At least now she could sleep soundly and warmly all through the night.
