Replacing my beloved but old heat pump

For the past month, I struggled to regulate the temperatures at home because my heat pump was acting up. It had since lost its efficiency. Though it was still working, the house was not getting cool enough. I had tried HVAC maintenance, but even that was no longer working. I had to admit that the HVAC system had served me long enough, and it was time for a new one. I called the residential HVAC provider, and they shared a catalog that included the price of each quality air conditioner. After going through it, I sought the advice of a cooling representative because I did not want to gamble regarding indoor air quality and comfort. I was also not very picky regarding HVAC brands because I was on a tight budget. I clarified to the HVAC technician that I wanted a zone HVAC, which was more technologically advanced, to lower my energy bills. Any amount of decrease from my previous would be welcome. I checked various local businesses to compare the overall price, but they were almost similar. Even on a tight budget, I still wanted to include an indoor air cleaning system because my allergies had recently taken a turn for the worst. The cooling technician also insisted that I replace my old regulator with a digital thermostat, which was much better. After we had settled all the above, we agreed on the installation date. When they installed the HVAC, the tech told me that it was important I schedule an HVAC service plan so that I could keep the system running optimally for years.
