Common HVAC Problems
Problem: My Air Conditioner Isn’t Cooling Effectively
Potential Causes/Solutions: Possible causes include refrigerant that is low or leaking, thermostat issues or a dirty filter. You can (and regularly should) change your filter and check to make sure your condensate drain is not clogged. Also check the thermostat to make sure it is set properly and is reading the correct temperature. Issues involving refrigerant are generally best handled by an HVAC professional.
Problem: My Heating System Keeps Turning On and Off
Potential Causes/Solutions: Your HVAC equipment cycles on and off based on the temperature detected by the thermostat sensor in your home; if the sensor isn’t working properly, your HVAC system does not know when to turn on and off. This wastes energy, costs you money and wears out your equipment. There may be other causes at play, but sometimes the fix may be as easy as changing the batteries in your thermostat or replacing it with a new one.
Problem: My Central AC Isn’t Working At All
Potential Causes/Solutions: First, make sure your thermostat is functioning. Also, your compressor and fan controls could be worn out from turning on and off too frequently. If so, you’ll want to check (or have a professional check) your unit’s electrical connections.
Problem: My HVAC System Has Limited Air Flow
Potential Causes/Solutions: Your ducts could be clogged or constricted, or leaking air. If so, you may need to get that ductwork cleaned and air-sealed. Be aware that your filter could also be part of the problem, restricting airflow through the unit, cutting its efficiency and reducing its ability to cool the air.
Problem: My Energy Bills Are Unusually High
Potential Causes/Solutions: A spike in operating costs most often signals inefficient operation. After a dirty filter, the most likely culprit may be a choked condenser coil. If so, it is probably time for a tune-up.
Frequently Asked HVAC Repair Questions
Q: What does HVAC stand for?
A: Heating, Ventilation and Air Conditioning.
Q: What are some of the signs that I need HVAC system repairs?
A: Signs that you may need HVAC service include: leaking around the outside unit, the air flowing into the house isn’t hot or cool enough, the unit is short-cycling or constantly turning on and off, higher-than-normal energy bills, unusual smells or excessive noise during start-up and operation.
Q: How often should I schedule HVAC system maintenance?
A: Many manufacturers require annual maintenance in their warranties. The most conscientious approach is to have your HVAC contractor come out twice a year to conduct pre-season maintenance check-ups in the spring (for summer) and fall (for winter).
Q: What’s the most important thing I can do to help keep my HVAC system running smoothly?
A: Change the filter regularly. This helps your heating and cooling system operate at peak levels while improving indoor air quality. The U.S. Department of Energy reports that changing your HVAC filter can lower your air conditioner’s energy consumption by 5% to 15%. High-quality 4-inch-thick filters should be changed every 6-9 months, while cheaper 1-inch filters may need to be replaced every 30 days.
Q: What certifications does an HVAC technician need?
A: HVAC technicians handling controlled refrigerant are required to have Environmental Protection Agency Section 608 certification. Additional licensing requirements vary from state to state; work on heating systems may require technicians to carry a Gas Fitter License, Oil Burner License or Sheet Metal License (when making duct work modifications). Homeowners can gain added peace of mind by choosing a contractor whose technicians receive advanced training and certification from NATE (North American Technician Excellence) — the nation’s largest nonprofit certification organization for heating, ventilation, air conditioning and refrigeration professionals.
Q: How important is regular HVAC maintenance for my indoor air quality?
A: Extremely important. The EPA reports that indoor levels of airborne pollutants may be 2-5 times higher (in extreme cases more than 100 times higher) than outdoor levels. This is particularly significant if you or any family members suffer from respiratory issues such as asthma.
