My mother had retired several long years ago and had used her pension payout to purchase a number of run-down residential properties that she intended to renovate and rent out, but she was elated by her purchase as this was an plan she had been mulling over for the past decade, however, within the past 5 years she had taken the steps to educate herself on the real estate business. She had also spoken to experts in the field and listened to testimonials from her peers who were also in the real estate business, however the renovations had started and I hired an air conditioner professional to assess the current AC system; She offered me an approximate quotation of the destruction parts and referred me to an air conditioner business who advised that I replace the outdated systems with current Heating & Air Conditioning systems as most heating and cooling component was very much old school and didn’t function well, and in one house, in particular, the plan clanked noisily when switched on. Since the houses were old, each was fitted with an oil oil furnace which seemed to be leaking as the sod on the grass was non-existent or had dried all the way up. The expert advised that a propane boiler would work best because of the gas lines that were attached to the houses as opposed to a warm water boiler which was expensive to install. She confirmed that with a quality air conditioner, I didn’t need a house air purifier which also meant less frequent air duct cleaning and washing of the washable filter. I familiarized myself with the wireless control equipment and intended to conduct periodic Heating & Air Conditioning service and air conditioner service service when the plan was installed. The entire process took a week and mum was glad with the fresh and clean air in the otherwise outdated looking houses.
