HVAC Questions? We Have Answers.
Frequently Asked Questions About Heating & Cooling
Whether you’re a first-time homeowner or a longtime customer, HVAC systems raise a lot of questions. Below are straightforward answers to the most common things we hear from homeowners across Mount Laurel, Cherry Hill, Voorhees, Moorestown, and surrounding South Jersey communities.
Most central air conditioners last 15 to 20 years, while gas furnaces typically last 15 to 30 years depending on the brand, maintenance history, and usage. Boilers can last 20 to 30 years or more with proper upkeep. Regular annual maintenance significantly extends the lifespan of any system.
Standard 1-inch HVAC filters should be changed every 1 to 3 months during periods of regular use. Thicker media filters (4 to 5 inches) can last 6 to 12 months. A dirty filter restricts airflow, forces your system to work harder, and reduces indoor air quality.
A furnace that runs without producing adequate heat is often caused by a dirty air filter, a malfunctioning thermostat, a faulty heat exchanger, or a problem with the ignition system. If the issue isn't resolved by replacing the filter or checking thermostat settings, contact a certified HVAC technician to inspect the system safely.
Common causes include a dirty air filter, low refrigerant levels, a frozen evaporator coil, or a failing compressor. If your AC is running but not cooling effectively, shut it off to prevent further damage and call Mount Laurel Heating & Cooling at (856) 722-7003 for a diagnostic visit.
