Heating and cooling systems are a vital part of daily life. We rely on our heating and cooling systems for indoor comfort year-round, so it pays to have some basic heating and air conditioning information at your disposal. With a bit of knowledge, you can prevent many HVAC problems from developing, keep energy costs as low as possible and take preventive action when problems occur.

Common Air Conditioning Problems and Heating Issues

Basic heating and air conditioning information includes being able to identify HVAC warning signs and when to call for service vs. when to try to fix the problem yourself. Heating and cooling systems will usually alert you to issues early on. If the symptoms aren’t treated, though, the problem gets worse. Familiarize yourself with any of these HVAC red flags and call for service ASAP:

  • System makes loud odd, unusual or strange noises
  • Heating and cooling is uneven – some rooms are too hot, others are too cold
  • Utility bills are increasing every month
  • There is weak airflow from the vents
  • Thermostat setting doesn’t match indoor air temperature
  • Furnace burner light is yellow, not blue
  • Air conditioner is leaking indoors

Preventive HVAC Maintenance

Many common air conditioning problems and heater problems result from poor HVAC maintenance. At Siemer Heating & Cooling, one of the most helpful tips we offer is that air conditioners should be serviced every spring and heat pumps/furnaces should be serviced every fall. Preventive maintenance will extend the life of your HVAC equipment, help it to function efficiently and reduce the potential for costly breakdowns and repairs.

You can do your part to maintain heating and cooling equipment by keeping the air filters clean. Most filters should be cleaned or replaced monthly, especially if you have pets. Clean filters reduce airborne pollutants, keep HVAC equipment from overheating and help the system to function efficiently.

Energy-Efficient HVAC

Whether you have an older HVAC system or a new, high-efficiency heat pump, furnace or air conditioner, you can save money on energy costs by following these helpful tips:

  • Install and use a programmable thermostat
  • Lower the heat or reduce the AC when you are sleeping and/or when no one is home
  • Let the sunlight help to heat your home in winter and close the curtains to keep sun out in summer
  • Install ceiling fans to circulate cooled air
  • Keep your outdoor HVAC compressor unit clear of debris and foliage
  • Clean or replace air filters regularly
  • Have your insulation checked and add more if needed

If you have a heat pump, furnace or air conditioner that’s over ten years old and needs frequent repairs, consider upgrading to a new, high-efficiency system. Heating and cooling systems get more efficient every year, so the older your system, the more you will save on energy bills with a replacement. The monthly savings can be enough to offset installation costs over time. Read our blog for more HVAC tips and money-saving tricks.
