10 Most Common Heating and Cooling Problems

In Sarasota, Florida, HVAC units work hard year-round to keep homes comfortable, especially during long summers. Here are ten of the most common heating and cooling problems.

Improper Operation

Air conditioners are not meant to cool the outside. As our parents used to say, “we aren’t cooling the neighborhood.” First, close all your windows and doors. Next, check to be sure you have power to the air conditioner. Start by checking fuses or circuit breakers. Reset your unit by allowing it to cool down for five minutes before resetting the breakers. Then, verify that the thermostat is set for the right temperature and appears to be trying to turn on the air conditioning at the right temperature.

Faulty Installation and Poor Maintenance

Problems often result from faulty installation, poor service, and neglect. If your central air is installed improperly or not charged correctly, expect leaky ducts, low airflow, and inefficiency. Keep filters and coils clean to keep your unit working efficiently. The compressor or fan may fail if they are overly exposed to dirt and allergens. Be sure that intakes are not blocked so that your unit gets adequate airflow.

Refrigerant Leaks

Low refrigerant means either an installation issue or a leak. Adding more refrigerant is not the answer. Rather, have a technician fix the leak. He can recharge the system with the right amount of refrigerant and will know how to repair a faulty installation.

Drainage

Be sure your condensation drain isn’t’t clogged and is working properly. If there is water on the floor near the furnace, the drain may be plugged up.

Unit Turning On and Off

If you HVAC unit is always turning on and back off, you can expect the compressor and fan controls to wear out. This is especially true if your system is oversized. Have a technician check for this and any corrosion on the wires and terminals.

The Thermostat

Thermostat malfunctions cause heater and furnace issues. Whether you have a digital or manual thermostat, a malfunction can cause the fan to stop blowing correctly, leaving you without enough heat this winter. If you suspect thermostat issues, have a professional check for problems as quickly as possible.

The Filter

If you can’t remember the last time you replaced your air filter, your furnace is likely clogged with dust and debris. When the filter isn’t changed on a monthly basis, your furnace has to work harder to distribute heat through your home. Replace your filter monthly for proper air flow throughout your home. Standard air filters are effective and highly affordable.

Wear and Tear

Your heater or furnace may be suffering from wear and tear. Electrical components, fan motors, ball bearings, and belts can all break, causing your furnace to stop working completely. The best way to prevent this type of problem is a yearly maintenance inspection to have all components thoroughly checked. Strange noises or smells are a sign that a belt or bearing isn’t functioning correctly.

Pilot or Ignition Problems

This is a common issue that occurs in both older and newer models of furnaces and heaters. It can also occur with hot-surface ignition or intermittent pilot lights and may be caused by faulty electrical components or your thermostat. When your pilot won’t ignite, it’s an issue that should be dealt with right away. You won’t have any hot air in your home until the problem is fixed.

Lack of Maintenance

This is a huge cause of furnace and heater malfunction. People often ignore their furnace until something goes wrong. Lack of yearly maintenance can shorten the life of your system and leave you without heat in the winter. There are ways you can prepare your heating system for winter, such as test firing it before you need it and making note of any strange sounds or smells.
