Why Pre-Summer Maintenance Is Essential for Your Cooling System

Published on May 9, 2025

As the temperature begins to rise, your air conditioning system is about to become the most

important appliance in your home or business. In 2024, NYC experienced an unprecedented number of scorching days, with Central Park recording 15 days at or above 90°F by mid-July. This intense heat, combined with high humidity, turned the city into a sweltering environment, making daily life challenging for residents.  

For brownstones and pre-war apartments residents, the summer heat can be harsh as these buildings often lack modern insulation and central air conditioning that causes interiors to retain heat and making cooling efforts less effective. In this case, proper maintenance before summer hits becomes essential. Here's why scheduling a professional check-up is highly recommended.

1.    System Check

Before starting the cooling system, you want to make sure the filters are clean, the refrigerant level is correct and the coils are not clogged. The next important thing is to have the electric connections check after the system has been resting all winter. A well-maintained system runs at peak efficiency, keeping your space at the desired temperature, and also helps to extend the life of the equipment.  

2.    Stay Warranty-Compliant

Most manufacturer warranties require annual or regular maintenance. Skipping your seasonal check-up could void your warranty coverage, leaving you responsible for repairs or replacements that might have been covered by the company.

3.    Improve Indoor Air Quality

Dirty filters and buildup inside your system can circulate allergens, dust, and humidity throughout your space. Pre-summer maintenance includes cleaning and replacing air filters, which contributes to healthier indoor air especially important for allergy sufferers.

What’s Typically Included in Professional Air Conditioner Maintenance

When a professional AC maintenance is done it goes beyond just a quick filter change which some homeowners think is the only required thing for the system to run smoothly. There is much more to it! Not only does it involve a detailed inspection, cleaning, and testing of your system but it also ensures that your system is running safely and efficiently. During the visit, a technician may inspect and clean components such as the evaporator and condenser coils, air filters, blower assembly, and the condensate drain line and pan. Electrical connections are typically examined and may be tightened to ensure safe operation. Performance testing may include checking thermostat settings, refrigerant pressure levels, running the system through a full cycle, and evaluating air temperature differences before and after cooling. In some cases, adjustments or minor repairs may be made, such as replacing excessively dirty filters, inspecting belts and motors for wear, and checking the alignment or lubrication of fan blades and other moving parts. The specific tasks performed can vary based on the system type, age, and current condition.
