Ductless mini-split systems in Smithsburg, MD, operate relatively quietly under normal conditions. While you may expect some sounds from your ductless mini-split, there are strange noises that you should never ignore.

Hissing

A hissing or high-pitched sound from your ductless mini-split should raise concerns about the health of your equipment. The common cause of the noise is a refrigerant leak from loose valves or damaged coils. The refrigerant facilitates heat exchange that your system can’t function without.

Neglecting to schedule a repair may lead to the destruction of the compressor, resulting in the replacement of the entire system. Unfortunately, a refrigerant repair isn’t a DIY task as it requires professional handling for safety.

Grinding

The air handlers in your mini-split systems contain a series of greased bearings. Over time, the bearings wear out and friction between them causes loud grinding noises. If you hear this sound, contact an HVAC service technician immediately before the air handlers burn out.

Rattling

A rattling sound indicates loose or damaged metallic parts in the ductless mini-split. A routine maintenance check will help to avoid such noise. During the session, your HVAC service technician will tighten loose bolts and repair or replace broken parts.

Buzzing or Humming

Buzzing or humming sounds signal electrical malfunctions in the compressor. It implies your system is getting an odd number of amps due to a defective contactor relay switch. Sometimes, the sound could be due to the starting capacitor or a failing motor.

Resolving the issue requires expert knowledge to avoid further complications or damage to other components. Contact a trusted HVAC provider in Smithsburg, MD, for prompt and accurate ductless mini-split repair services.

Helping your HVAC system in Clear Spring, MD, operate at peak efficiency throughout the year requires a little effort and a lot of care. While you should leave most HVAC tasks to a professional service technician, including tuneups and repairs, you can do some on your own without worry. Here are four to add to your spring to-do list:

Change the Filter Every Month

Before turning on your air conditioner for the first time this cooling season, change or clean its filter, depending on your system. Continue to do this every month during the spring and summer to facilitate proper airflow in your AC system. By doing so, you’ll minimize cooling costs and prevent breakdowns. You’ll also protect your indoor air quality.

Clear Debris Around the Outdoor Compressor

It’s likely that branches, leaves, and other yard debris have collected around your air conditioner’s outdoor compressor during the winter months. Take some time to remove these and ensure there’s at least a few feet of clearance around your AC system. This will ensure your air conditioner doesn’t struggle to maintain a cool indoor temperature.

Upgrade Your Manual Thermostat

Do you still use a manual thermostat to control your home’s temperature? You’re missing out on some serious energy savings and other benefits that programmable models offer. With a programmable or smart thermostat installation, you’ll enjoy a long list of features that add comfort, convenience and cost savings to your life.

As noted, it’s best to leave most HVAC tasks to a trained, certified and experienced professional. The team at Hagerstown Heating & Cooling is here to help prepare your air conditioner for the upcoming heat.
