3 HVAC Leaks to Watch Out For in Your Newport News, VA Home

One of the most common problems to watch out for is a leak in your Newport News, Virginia, home’s HVAC system. An air leak in your ductwork or your insulation can waste energy, increase your utility bills, and let contaminants like pollen and dirt into your home. You should also look for water, refrigerant, and gas leaks in your heater or air conditioner to prevent a dangerous situation from occurring.


The evaporator coil in your air conditioner’s indoor air handler is full of cold refrigerant. A fan blows warm air over the coil to cool it. When condensation forms on the cold coil, it should drip into a drain pan and down a condensate drain line that leads outside your home.

Low airflow from a clogged air filter or a malfunctioning fan can freeze the evaporator coil, keeping the drain pan from being able to hold all the water when it melts. You could also have a condensate drain line that’s clogged with dirt or leaves. If you see water near your air conditioner, have it checked by a professional like the ones at Lighthouse Mechanical.


A refrigerant leak can cause freezing on your evaporator coil as well. You could also notice an uncomfortable home, high utility bills, an unpleasant smell, or a whistling or hissing noise from refrigerant escaping. Your HVAC system could also stay on without heating or cooling your home well.


If you have a gas furnace or any gas appliances, you should always be alert for a strange smell that might signal a leak. Leave your home immediately and call your local utility company for help. Gas can cause suffocation or even an explosion, so you should always contact an expert if you suspect a leak.
