Back when I did not have a dual fuel system, I had installed a window unit in my bedroom alongside the central air conditioning system to help with energy efficiency and also for my indoor comfort since it is where I spent most of my time when I was at home.
After I got my hybrid system, I replaced the analog thermostat with a smart one, allowing me to change or adjust the temperature in the house even when I was at work.
All this so that I could save more on the energy cost. I knew the SEER rating of my old HVAC system could have been better since it was an old model, but I could not afford to have quality HVAC equipment. I was even dreading the service plan I had signed up for with the air conditioning company, but I knew I had stretched my luck with the air conditioning filter replacement and some other a/c repair that the cooling products required. I needed to get a new washable filter, but I kept telling myself that I lived close to the ocean, so it was not necessary; in truth, the air purification in my place was not so good and needed a major a/c rep. With the current pay cuts at my workplace, I could barely afford an a/c workman fee. I was feeling very frustrated since I was living on the bare minimum. If I passed the last interview I attended, it would relieve me greatly since it was a well-paying job. In the meantime, a/c care had to take a back seat. I had even screened my windows with a mesh to keep the bugs out when I opened the windows at night for cooling. I hope to get the job and afford a new a/c install.
