Smart Programs For Split System Air Conditioner Examined HVAC Service Easy DIY Maintenance Tips and Quick Fixes There are a number of simple, easy-to-perform types of maintenance that any homeowner can do on their own to keep their HVAC system running properly. Here are just a few that are recommended. Clean and Replace Filters Filters are easy to remove, clean Split System AC or replace. They are also comparatively inexpensive and require very little time or effort to clean, and even less to replace. We suggest to clean or replace the systems’ filters at least once every three months. If there are pets, clean or replace them every two months, as loose pet hair can clog up a filter very quickly. Clogged filters block air flow, which means the equipment has to work harder — and use expensive energy — to heat or cool the home. Replace Thermostat Batteries (Or Replace Old Thermostats) Many thermostats fail simply because their batteries are low. (Countless times a repair call is made when the only problem was a dead battery in a thermostat). Replacing those batteries is usually very simple. Even if the printed manual is no longer handy, check online to see how to do so correctly. Older thermostats should also be replaced with newer, smarter and more energy-efficient models. Most of these modern thermostats also come with instructions on how to install them for the DIY'er. Check the Circuit Breakers and Safety Switches An overworked air conditioner or heating unit will draw more amps than usual (or is safe). When it does so, the system will trip a circuit breaker or a safety switch. So, before picking up the phone to call a pro take a look at the circuit breaker panel and flip any tripped circuit breakers. That might just do the trick. If it doesn’t, or if the breaker keeps flipping, then there is a more serious problem, one that requires the services of someone who knows HVAC repairs. Check for Blockages at Vents, Along Ducts and Around Compressors Many heating and cooling issues come down to blockages affecting either air flow or the condenser. Outdoors, ice, leaves, tall grass or other debris can be the culprit. Indoors, a piece of indoor ductwork may have become disconnected or dented. Most vents, ducts, compressors and condensers can be checked easily, although some may be in difficult to access areas such as crawl spaces. Again, that’s where a trained HVAC technician may be your best bet. Whatever the case, DIYers should always take proper precautions when attempting to fix HVAC issues on their own. Getting advice from the professionals is the first place to start. Clean Outdoor Condenser The AC unit outside the home should be cleaned with water once a year. This will allow the system to breathe and function at peak performance. If the coil is excessively dirty a professional should clean it with chemicals specifically designed for coils.
