Why Ice on Your Air Conditioner Isn't Normal

An air conditioner is an essential appliance for New York homeowners, especially during the peak of summer. If you spot ice building up on your AC, it's time to contact Reliable Heating & Cooling, a trusted Staten Island HVAC repair company with over 15 years of industry experience. Ice on your air conditioner isn't normal. Don't worry, though! Our friendly team is here to help.


A Refrigerant Leak

A refrigerant leak is a serious issue that requires immediate professional attention and repair. Exposure to air conditioner refrigerant is not only hazardous to your health but also to the environment. Ice forming on your air conditioner is a red flag that you need to contact our Reliable Heating & Cooling team of experts right away. We possess the necessary tools, training, and experience to restore your home's comfort and safety efficiently, providing you with peace of mind.


Dirty Coils

Regular maintenance of your HVAC system is a wise investment that can save you money in the long run. Dirty evaporator coils, a leading cause of ice buildup, can be easily identified and cleaned during these checks. As dirt and grime form layers on the coils, it reduces their ability to absorb heat and keep your home properly comfortable. If the evaporator coils need to be cleaned, you might also notice water leakage around the unit and a lack of cool air indoors.


Reliable Heating & Cooling is your trusted partner in ensuring your HVAC system operates at its full potential. We offer multiple
maintenance plans to our valued customers, allowing our technicians to assess and diagnose any potential problems before they escalate. Your active maintenance plan will include additional benefits, such as discounts on repairs, priority service for emergencies, and no overtime fees for any future emergency appointments. By signing up for a maintenance plan, you can save money and ensure the reliability of your system.


Obstructed or Closed Vents

If ice is forming on your air conditioner, be sure to check your vents. Are there any obstructions? Are any of the vents closed? Adequate airflow is crucial for an HVAC system to operate at its peak condition. If there is little to no airflow, problems such as frost buildup will occur.


Dirty Air Filters

How often do you change your air filters? Regular replacement, at least once every three months, is essential to prevent clogging caused by dust, pet dander, smoke, and other airborne allergens. Failure to do so can result in blocked airflow, which in turn can lead to system failure. If you live in an area with high indoor air pollutants, more frequent changes are advisable. Reliable Heating & Cooling can assist with this crucial maintenance task.


Dust, pet dander, smoke, and other airborne allergens can lead to clogged air filters if they are not changed frequently enough. Blocked airflow can lead to the need for
repairs or even a complete system failure if the problem is left unresolved for too long. Reliable Heating & Cooling can help! If you're experiencing issues with your air conditioner, we're your go-to Staten Island HVAC repair company, ready to handle all your HVAC needs.


A Faulty Thermostat

Is your thermostat accurately reading indoor temperatures? A faulty thermostat can cause your HVAC system to run constantly, leading to faster wear and potentially causing ice accumulation on your air conditioner. This added strain on the system will also increase your monthly energy bill. Regular checks and maintenance of your thermostat can help prevent these issues.


Don't Delay

Ice accumulation on your air conditioner is a warning sign that it requires professional repairs. Don't delay, call Reliable Heating & Cooling today at 347-349-1481 to schedule service.
