In Texas, where summers are long and temperatures stay high, air conditioning systems work much harder than in other regions. Because of this, professional AC maintenance should be scheduled at least once a year, ideally in the spring before peak cooling season begins. Regular upkeep is crucial, as neglect allows dirt to build up in coils and filters, reducing efficiency and leading to frequent breakdowns.
Over time, this lack of care not only increases utility bills but also shortens the overall lifespan of the equipment. Investing in routine maintenance truly pays off, as it lowers monthly energy costs, extends the life of the system, and helps avoid costly emergency repairs. In fact, a well-maintained unit can last years longer than one that has been overlooked. The cost of a professional AC tune-up in Richardson, TX will vary depending on the size and condition of the system, but it remains an affordable way to protect your investment.
