The temperatures are gradually dropping here in Maryland and we even had our first frost. Have you turned your thermostat to heat yet? Even if your home has been maintaining a comfortable temperature, it’s a good idea to test your heating system before you actually need to use it. Pick a cold streak and run your furnace for a few days to see how it works. If there are any issues, it’s better to catch them early, so that you can have your Maryland HVAC contractor fix them in time for winter. Meanwhile, there are a few other fall maintenance tweaks you can do to ensure your HVAC system is ready for the cold season.


Depending on the type and model of your HVAC equipment, you either have a single-use or reusable air filter. It needs to be replaced or cleaned anywhere from once a month to once ever three months. If you are not sure what kind of air filter your system uses, consult with an HVAC expert—we can even perform the installation for you. Once you see how it’s done, you can do it yourself next time. An air filter does an important job of catching any dust and debris sucked in from your return air ducts. A dirty and clogged filter leads to more strain on your HVAC system and reduced energy efficiency.


If you are not an HVAC professional, you shouldn’t be getting too involved with the inner workings of your HVAC equipment. However, it doesn’t mean you should keep it locked up in a utility room and avoid that place as if it’s cursed. Before you start the heating season, go ahead and inspect your furnace or heat pump. Just walk around it and take a note of any damage or things that seem out of place. Look for rodent-damaged or corroded wiring, dusty coils and “stuff” that could be blocking the air circulation around your unit. If you detect any issues you don’t feel comfortable addressing, give a call to your trusted Maryland HVAC maintenance expert and let us handle the repair.


Just because your thermostat works, doesn’t mean it works properly. To test it, place a second thermometer next to your thermostat to ensure the temperature readings are identical. Then also measure temperature in a different area of the room to see if it matches up with the thermostat reading. Besides a broken thermometer, you could have a problem with the wrong thermostat location. When a thermostat is close to a heating source or a cold draft, the temperature it reads is not reflective of the rest of the house. This can lead to either too much or not enough heat.


While you can accomplish the above steps on your own, it’s still worth hiring a professional to perform seasonal maintenance on your HVAC equipment. Here are a few things we can do to make your system run smoothly all winter long:

  • Tighten electrical connections and measure current
  • Lubricate all moving parts
  • Inspect fuel lines and tighten connections
  • Measure and calibrate airflow
  • Check and clean the ignition and burner assembly
  • Test carbon monoxide levels

Tuning up your HVAC system prior to each heating/cooling season helps ensure its optimal performance. This means not only a comfortable home environment for you and your family, but also noticeable savings on your energy bill.
