A/C Maintenance
Perfect Star’s air conditioning maintenance technicians are certified and undergo weekly state-of-the art specialized training to diagnose and repair any issues affecting your home’s central a/c system.
Think of your air conditioner like a car, if you don’t change the fluids and filters with regular tune-ups your system will not continue running as efficiently as it should and will eventually breakdown…often times when you need it most. This could end up costing you thousands of dollars in repair or replacement. Being that the Average US home puts over 4,000 hours of wear-and-tear on their HVAC system each year, regular air conditioning maintenance is critical to saving you time and money, all the while keeping you comfortable when it matters most.
Perfect Star offers a variety of maintenance programs, from one-time tune-ups to regularly scheduled seasonal maintenance as a Perfect Star Performance Member.
So don’t wait until the blistering heat of an East Bay summer sets in for your A/C to break down. Being proactive with regular maintenance not only improves your cooling system’s efficiency, thus reducing your energy bill, it extends the life of your system.
