I don’t mean to brag, even though I take really good care of our Heating, Ventilation, and A/C system. I consistently keep up with repair tasks that I can do plus have certified Heating, Ventilation, and A/C specialists check our system over twice yearly. The specialists that come over are pretty good for the most part. I usually get praise for keeping our HVAC system so well maintained. I absolutely think that it has extended the overall life of our Heating, Ventilation, and A/C system. I take pride in switching out the seasoned filters with modern, high quality new filters. I clean the outdoor condenser unit by myself. I just shut the power off to it and remove the grill. After that, I remove all debris. I make sure there are no plants or vegetation somewhere in or around the unit. I spray towards the outside of the unit to remove the blockage in the coil fins. I am extra careful so I don’t bend those fins. They are rather delicate. I must say that it’s particularly satisfying to be able to handle some things on our own as a family when it comes to our Heating, Ventilation, and A/C system. I consistently make sure to leave the rest to the professionals though. I do make sure that they have our HVAC duct clean. I do have a few pets and I absolutely don’t want our HVAC duct to become blocked. That would raise our utility bills, guaranteed. I do appreciate saving money so I will never let that happen. It’s our philosophy to consistently be proactive when taking care of the home. The most important thing is to maintain your health and your home is to keep the HVAC system in pristine order.
