My fiance and I try to stay on top of household chores and repairs. Some of that is due to our boys, because both of us both delegate chores very well, and our teenage sons are responsible for keeping the garage and outdoor areas clean. Both of us also have a nine year old, who is responsible for taking out the trash and recycling. Our nine year old also unloads the dishwasher every night. Between the three of them, they stay busy enough to stay out of trouble, and my fiance and I are free to worry about the other chores! Both of us have a schedule board that tell us when each task needs to be performed. Biweekly, we change the air filter on the Heating, Ventilation, plus A/C unit! Every third month, my fiance changes the batteries in the smoke detectors. The water filter in the refrigerator is also changed every 90 days. When both of us started to notice some significant wear and tear on our Heating, Ventilation, plus A/C unit, we enrolled in a Heating, Ventilation, plus A/C service plan. the HVAC service plan is a complete comprehensive plan, set up to help increase the life of your Heating, Ventilation, and A/C equipment. Our contract gives us two comprehensive check-ups on our Heating, Ventilation, plus A/C unit per year! One of those visits is set up during the fall, and a the other is set for the Springtime months. During this time, the Heating, Ventilation, plus A/C contractor completes a thorough investigation of our system. These visits are offered at a discounted rate of $19.00, plus any parts used. I suppose the Heating, Ventilation, plus A/C device always works better after a visit from the Heating, Ventilation, plus A/C wiz-kids!
