Summer heat in Upstate NY can push your air conditioning system to its limits. While temperatures may not reach the extremes of southern states, the combination of heat and humidity creates a significant burden on cooling systems. The good news? Most AC breakdowns are preventable with proper maintenance and attention to early warning signs.
Understanding these common issues and taking proactive steps can save you from sweltering through a heat wave while waiting for emergency repairs. Grasshopper Heating, Cooling & Plumbing has been helping Upstate NY homeowners maintain comfortable homes since 2016, and we’ve seen these problems time and again during peak summer months.
Dirty or Blocked Condenser Coils & Outdoor Units
Your outdoor condenser unit works hard to release heat from your home, but it can’t do its job effectively when surrounded by debris. Dirt, leaves, grass clippings, and other outdoor elements accumulate around the unit throughout the year, restricting crucial airflow and forcing your system to work harder.
When condenser coils become dirty or blocked, your AC struggles to cool your home efficiently. This leads to higher energy bills and puts unnecessary strain on system components that can result in premature failure.
Prevention Tips:
- Maintain at least 2 feet of clearance around your outdoor unit
- Clean coils at the start of summer and again mid-season if needed
- Trim grass and remove debris regularly as part of your maintenance routine
- Gently hose off dirt and cobwebs from the unit’s exterior
Clogged Air Filters
Air filters are your AC system’s first line of defense against dust, pollen, and other airborne particles. When filters become clogged, airflow decreases dramatically, reducing your system’s efficiency and potentially causing evaporator coils to freeze.
Dirty filters don’t just hurt performance—they can lead to costly repairs and poor indoor air quality for your family.
Prevention Tips:
- Check filters monthly during heavy-use summer months
- Replace filters every 1–2 months, or more frequently if you have pets or excessive dust
- Use pleated filters for better air quality and longer-lasting performance
- Set calendar reminders or ask Grasshopper about filter replacement programs
Refrigerant Leaks & Frozen Evaporator Coils
Low refrigerant levels, often caused by leaks in the system, severely impact your AC’s cooling capacity. When refrigerant is low, the evaporator coil can freeze, creating a cycle of poor performance and potential damage to other components.
These issues require professional attention—adding refrigerant without fixing the underlying leak is a temporary solution that wastes money and doesn’t address the root problem.
Prevention Tips:
- Schedule pre-season inspections to check refrigerant levels and system condition
- Don’t ignore signs like ice on indoor coils or reduced cooling capacity
- Call professionals immediately if you notice frozen coils or inadequate cooling
- Ensure any repairs properly fix leaks before refrigerant is added
Thermostat & Electrical Component Failures
Your thermostat is the brain of your cooling system, but even smart thermostats can malfunction or be improperly programmed. Electrical issues like faulty capacitors or damaged wiring can also cause system failures or inefficient operation.
These problems often develop gradually, so your AC may seem to work but not cool effectively or cycle on and off irregularly.
Prevention Tips:
- Verify your thermostat is set to “cool” and positioned away from heat sources or direct sunlight
- Consider upgrading to a programmable or smart thermostat for better control and efficiency
- Include electrical component inspections—wiring, capacitors, and connections—in annual maintenance
- Test your thermostat’s accuracy with a separate thermometer periodically
Obstructed Ducts, Mold & Drainage Problems
Ductwork problems reduce your system’s ability to deliver cool air effectively throughout your home. Leaky or blocked ducts waste energy and create uneven temperatures. Meanwhile, humidity can lead to mold growth in ducts or around the indoor unit, affecting air quality and system performance.
Clogged condensate drain lines can cause water damage or automatic system shutdowns designed to protect your home and equipment.
Prevention Tips:
- Inspect visible ductwork for leaks or damage; seal with appropriate materials
- Watch for musty odors that may indicate mold growth—address promptly with professional cleaning
- Keep condensate drain lines clear and include drain checks in regular inspections
- Ensure adequate ventilation around indoor units to prevent moisture buildup
