How a Ductless Mini-Split System Works

Have you ever wondered how a mini-split system works? Whether you have your own ductless system or you’re considering ductless mini-split installation in the future, understanding mini-splits can give you a lot of important knowledge about your home’s comfort capabilities. Here’s a little more information about how ductless mini-splits work!

A mini-split system is an advanced modern HVAC system capable of heating and cooling your space without the need for ductwork. Mini-splits can have many benefits in any type of living space, but they are particularly useful for homes or commercial buildings that have additions or rooms that are difficult to reach with traditional ducts. An additional benefit of going ductless is the elimination of dust and dander in the air often seen with traditional ducted systems.

A mini-split system behaves much like a miniature air handler or heat pump. The system consists of an outdoor unit and one or more indoor unit(s), which are connected by a refrigerant line. The outdoor unit contains a compressor, which pumps refrigerant through the system. Indoor units, which are usually mounted on the wall or ceiling, contain an evaporator coil and a fan. These parts allow the unit to operate as both a heater and an air conditioner.

Mini-Split Cooling

When the temperatures rise and you reach for your thermostat to turn on the air conditioning, the refrigerant flows through the evaporator coils, absorbing heat from the room and cooling the air. Since the indoor unit is mounted on the wall or ceiling, the fan can then blow the cool air back into the room without the need for ductwork.

Mini-Split Heating

The system works in the opposite way when heating is required. The outdoor unit still pumps refrigerant through the system, but this time it absorbs heat from the outside air and brings it inside to warm the indoor space. This process is possible even in colder temperatures because the refrigerant is still able to absorb heat from the outside air.

Signs of a Broken Ductless Mini-Split

It can be difficult to tell when these combined heating and air conditioning systems are malfunctioning without advanced expertise, but there are some red flags you can look for. Here are a few signs that indicate you may need ductless mini-split repair service in Sussex County, DE:

Strange Noises

Just like standard air conditioning units, heat pumps, and many other types of HVAC units, faulty mini-splits can quickly become insufferably noisy. If your ductless mini-split is making strange noises like grinding, whistling, or hissing, it could be a sign of a broken fan, a dust-clogged filter, or a faulty compressor. Contact us for repair service, and we’ll get the job done right away.

Uneven Temperatures

Ductless mini-split systems are supposed to be an efficient way to distribute heating and cooling evenly throughout your living space. However, a problem with your heating and cooling system can definitely disrupt your home’s comfort. If specific areas of your house feel too cold or hot while the temperature in other locations seems fine, it could be a sign of a broken thermostat, a faulty installation job, or a refrigerant leak. Schedule a service appointment now, and we’ll take a look at your unit to make sure everything is working as it should.

Poor Airflow

If you notice weak or no airflow from your ductless mini-split unit, or it’s blowing hot air rather than cooling your home, it could be due to a clogged air filter, a damaged fan, or a broken motor. A technician will examine these components to determine whether the installation was handled well and if everything is working correctly. Then, our experts will make any necessary repairs so that your mini-split can once again meet your home comfort needs.

High Energy Bills

Your ductless equipment is designed to be efficient all year long, whether you’re using it to heat or cool your living space. If your monthly energy bills have increased suddenly, but you haven’t changed your ductless mini-split unit’s temperature settings, it could be due to a broken unit working harder to keep your home comfortable. Schedule repair ASAP and save energy, power, and money!

Foul Odors

Yuck, what’s that smell? If your ductless mini-split reeks of dirty socks, mildew, or another obnoxious odor while heating or cooling your home, it could be a sign of a refrigerant leak, mold growth, or a dirty filter. All of these can pose serious problems since leaking water or refrigerant can quickly fill your entire home with toxic mold and mildew. We’ll take care of the job so you don’t have to smell these disgusting scents while heating and cooling your home — or worry about breathing in toxic air!

Common Issues With Ductless Mini-Splits

Customers book ductless mini-split repair services in Sussex County, DE, for all sorts of reasons. However, ductless systems are definitely prone to some problems more often than others. Here are some of the most common problems people run into with their mini-split systems:

Leaking Refrigerant Line

If you notice a loss of cooling or heating capacity, it may be due to a refrigerant leak. Low refrigerant levels can occur due to a hole or crack in the drain line, which can in turn cause ductless systems to work harder than they need to. If you suspect that your mini-split is leaking water or refrigerant, take action ASAP before the problem causes further need for repairs. We can repair or replace the drain line so that your equipment is safe to use once again.

Clogged or Dirty Air Filters

You may not have dirty ducts to worry about when you don’t have ductwork, but HVAC system issues can still cause air quality problems. Dirty air filters can lead to poor air quality, limited airflow, and reduced efficiency. Therefore, it’s important to clean or replace the air filters regularly in all HVAC systems, including mini-split systems.

Frozen Evaporator Coils

If your unit’s coils freeze over, it may be due to a clogged filter, low refrigerant levels, or other issues. This problem is not exclusive to ductless units (it can happen with all types of cooling systems), but your unit can’t operate without a functioning evaporator system. Book repairs with a Top Flight technician now.

Electrical Issues

Just like any household heat pump, electric furnace, or central AC system, ductless units can run into electrical issues. Faulty wiring or electrical components can cause the system to malfunction, leading to reduced efficiency or a complete breakdown. To protect your system from this common problem, hire only experienced professionals for ductless mini-split installation. (It may be tempting to go with the cheapest contractor you can find, but trust us, cutting corners during the installation process can cost you a fortune later down the line.) Once installation is complete, don’t forget to schedule routine maintenance and system check-ups. The cost of investing in maintenance is much lower than having to prematurely replace your system, so it’s just common sense.
