Some of the many reasons to schedule regular air conditioning Wilmington DE maintenance from Joseph Frederick & Sons include:

  • Reliable Performance – Thorough inspection in the spring allows time to identify and correct worn or faulty components. Replacement parts can be ordered and installed, preparing your system for the summer workload. As a Carrier Factory Authorized Dealer, we rely on Factory Authorized Parts to restore original efficiency, sound levels, and durability. With careful adjustment, tightening, lubricating, refrigerant tests, airflow tests, and operational checks, the service technicians from Joseph Frederick & Sons promote smooth performance, helping to prevent the majority of problems.  You’ll enjoy uninterrupted and ideal comfort season after season.
  • Indoor Air Quality – Cooling equipment that is not properly maintained is a risk to your health. Insects, feces, and decomposing animals are just a few of the unpleasant things that can be hidden in the inner workings of an air conditioning unit. The increased temperature and moisture created by the cooling process facilitates the growth of natural organisms and accelerates the decomposition of animal and plant matter.  Mold, mildew, algae, and fungi can find the perfect home deep inside the unit, leading to restricted airflow, overworked motors, higher running costs, and degraded air quality. Millions of unwanted airborne particles may be introduced into the breathing air every time your cooling system is activated. Fatigue, coughing, congestion, eye irritation, asthma attacks, flu-like illnesses, aggravated allergy symptoms, and respiratory infections are some of the consequences of a contaminated air conditioner.
  • Cost Savings – A system that is clogged with dust and debris, or struggling with defective or worn parts, must work much harder to manage comfortable temperature and humidity levels. This places added stress on components, leading to costly repairs from HVAC companies in Delaware, while also increasing energy usage. As cooling capacity decreases, utility bills will steadily rise. Over months and years of service, there’s simply no way your system can meet manufacturer’s expectations for energy efficiency without regular upkeep. With meticulous cleaning, tuning, and adjustment, the team from Joseph Frederick & Sons will promote maximum efficiency and cost-savings.
  • Lengthened Service Life – By changing out faulty parts and optimizing performance, Joseph Frederick & Sons keeps your system operating in peak condition.
