Expert Service & High-Quality Replacement Parts for AC Repairs In & Out of Warranty

When you call NES Mechanical for air conditioner service, we'll use state-of-the-art diagnostic tools to pinpoint the underlying cause of your cooling problem. However, because we perform a thorough diagnostic of your entire air conditioning system, we also identify opportunities to improve your overall comfort and save you money. Before we begin repairs, we'll provide you with an upfront, written quote for your approval. Our service technicians arrive in fully stocked vehicles with many of the most commonly needed replacement parts, such as circuit boards, refrigerant lines, flux capacitors, compressors, fan motors, and more, so we can complete most air conditioner repairs on the first visit. We can also perform repairs to related HVAC equipment, including furnaces, ductwork, supply and return registers, thermostats, and electrical lines. If any specialty part is needed, we can order it and have it in stock within a few days.
