Yes, a once-a-year tune-up keeps the system efficient and helps it last longer. During the visit, a technician cleans coils, checks electrical connections, and swaps or cleans the filter. Catching small issues now stops bigger, pricier failures later, so that a quick appointment saves money and stress over the life of the unit.
Changing your AC filter every 30 days is necessary to maintain optimal performance and high indoor air quality. Regular filter replacement prevents dust buildup, ensures efficient airflow, and protects the system from stress that could lead to costly repairs. This disciplined maintenance routine not only boosts energy efficiency but also prolongs the lifespan of your unit by safeguarding its critical components.
An HVAC service plan is worth the cost, especially if you forget to schedule maintenance on your own. A service plan locks in yearly (or twice-yearly) visits, allowing a professional to identify small problems early, clean key components, and maintain energy efficiency. Many plans also include minor repairs or priority scheduling, which can pay for themselves if an unexpected issue pops up.
In a pre-season service visit, your technician gives your system a top-to-bottom check before peak season hits. Expect a filter change, thermostat test, condenser-line flush, electrical-connection check, and coil cleaning. They also tighten loose parts and make minor adjustments so the unit fires up without surprises when temperatures swing. That quick tune-up cuts the risk of mid-season breakdowns and keeps energy use in line.
