Is a ductless HVAC system a viable alternative for heating and cooling individual rooms in your home? Every day, ductless heating and cooling units are gaining market share in this country as more people decide that the answer is “Yes.”
The system consists of a compact, low-profile indoor air handler incorporating a coil and blower fan mounted on the wall or ceiling of the room. This unit connects via a narrow refrigerant conduit to a downsized outdoor heat pump behind or next to the house, about the size of a large suitcase. In winter, like any heat pump, the system extracts latent heat from outside air, concentrates it with a compressor, then conveys it indoors to the air handler where the coil and blower disperse heat into the room. In summer, the system reverses and cools the room by extracting indoor heat and conveying it outside to be released in outdoor air. A single outdoor heat pump unit can link to up to five ductless air handlers in separate rooms.
Ductless HVAC provides three advantages.
- In homes without ductwork for central heating and cooling—or where extending existing ductwork to additional rooms isn’t financially feasible—a ductless system permits low-cost, highly effective heating and cooling of individual rooms without relying on outmoded space heaters and clunky window air conditioners.
- Leaky, inefficient ductwork loses at least 25% of heating or cooling in most homes. Because a ductless system delivers heating and cooling without ducts, operation is more energy-efficient at lower cost. Ductless comfort control is also more accurate as each room has its own dedicated thermostat to individualize temperature to that space.
- Installation of ductless HVAC is far less intensive and disruptive than installing ducts and vents that require major construction. All that’s required are a three-inch hole in an exterior wall to route the refrigerant conduit outdoors, plus mounting the indoor air handler on a wall or ceiling. A two-person team can easily install a ductless system in a single room in one day.

If things go wrong with your cooling system, how much air conditioning troubleshooting should you attempt yourself? Where’s the tipping point when it comes to when to call in a qualified professional, instead? The fact is, technology incorporated in today’s central air conditioners is complex and beyond the expertise of the average homeowner. For this reason—as well as valid safety concerns and warranty restrictions, too—the list of DIY air conditioner troubleshooting is necessarily short.
Nevertheless, a few basic steps will at least eliminate obvious issues and narrow down the causes.
Air Conditioning Troubleshooting Tips Before You Call a Professional
A/C doesn’t start at all. First check the thermostat and make sure the system’s in “Cooling” mode. Also verify that the desired temperature setting is at least 5 degrees below the displayed room temperature. If everything appears correct, look inside the main electrical panel for any tripped circuit breakers. If you notice one, don’t reset it. Call a qualified HVAC contractor and inform them.
System runs but poor cooling performance, low airflow, etc. Inspect the system air filter. Does it appear dusty and dirty? Remove the filter and take it to a home center to buy a replacement. Install the new filter and check the airflow. Also, make sure nothing’s obstructing vents on the outdoor half of the A/C system: fallen leaves or objects someone placed on top of the fan grille can be the problem, as can encroaching weeds or other vegetation that obstructs side air vents. If the problem persists, you need professional help.
Leaking water. If you notice water around the indoor air handler, check the wide condensate drain pan situated underneath. Is standing water inside the pan? Overflow caused by a clogged condensate drain line is likely and will require a qualified HVAC technician to clear the clog. Another possible cause of leakage is ice forming on the evaporator coil inside the air handler. This is usually the result of a very dirty coil or low refrigerant level—both requiring professional service to diagnose and resolve.
If basic air conditioner troubleshooting hasn’t solved your cooling problems, contact a professional at Apollo Heating, Cooling, Electrical and Plumbing.
How long is it going to be before the highs start hitting the 80s or 90s? You know it won’t be too long with the hot Jacksonville summer arriving soon. To ensure your A/C can keep your home cool this summer, schedule air conditioner preventative maintenance now before the heat hits. With a maintenance plan, you and your home’s HVAC system are taken care of.
Quality HVAC air duct design plays a tremendous role in a home’s energy efficiency. A properly designed duct system can help your HVAC system deliver the right amount of conditioned air without wasting energy or creating excessive wear and tear on HVAC components.
The ductwork that distributes conditioned air throughout your home is a critical component of the HVAC system. Ensuring its not contributing to poor indoor air quality is important, and that’s when duct cleaning comes in. According to the Environmental Protection Agency (EPA), there are certain situations where it’s advisable to have a professional duct cleaning.
Though spring may seem so far away during the last hits of winter weather, warmer temps are just around the corner. Before you have to switch your HVAC system over to cooling mode, make sure you get the air conditioner ready for the warmer winds of spring and summer.
Many homeowners don’t spend much time thinking about indoor air quality, assuming that the air inside a house is generally safe. This often isn’t the case, though. Plus indoor air quality can decline significantly in winter, with lack of ventilation and extra sealing being common in most homes. Family members with allergies or asthma are the most likely to suffer from poor indoor air quality, though it affects everyone. Fixing the issue can be fairly easy, however, if you follow a few simple steps to minimize indoor air pollution in your home.
Air filters are an essential part of the HVAC system. Not only do they keep dirt and other harmful contaminants away from HVAC components where they can cause damage, but they also remove those contaminants from the air you breathe.
But what kind of air filter should you use in your home? Which one will most effectively raise your indoor air quality?
When it’s time to replace the HVAC equipment in your home, it pays to look at the advances made in heat pump technology. The features available on today’s heat pumps offer greater comfort, enhanced energy efficiency and longer equipment life. (more…)
Why does a ductless system offer greater power and efficiency than a standard central furnace and A/C? It’s a simple answer — no ducts. In most houses, one of the largest energy losers on the premises is the heating and cooling ductwork. Residential ductwork is often not constructed to last the life of the home and deteriorates over the years. A ductless system combines heat pump efficiency with duct-free installation to provide single-room heating and cooling in houses where adding ductwork isn’t desirable or feasible.
Here are three reasons why a ductless system may be the best option for bringing comfort and efficiency to single rooms or enclosed spaces in your home.
A ductless heat pump incorporates a low-profile indoor air handler and a compact outdoor unit comprising the coil and compressor. A narrow insulated conduit conveys refrigerant as well as electrical power. The indoor and outdoor unit can be as much as 50 feet apart and only a three-inch hole is required in an exterior wall to accommodate the refrigerant conduit. In most homes, experienced installers can do the job in a day.
Ducts lose an average of 30 percent of conditioned air. A furnace or A/C must run longer cycles to make up for the lost air, increasing energy costs. A ductless heat pump conditions an individual living space by moving heat in or out. Heat is directly added or removed by heat pump technology, not conveyed through ductwork.
Unlike other options such as window A/C units or space heaters, a ductless system fits seamlessly into your decor. The indoor air handler is unobtrusive and mounts on the wall, ceiling or a floor stand. Optional covers are available to match color schemes. Outside, the heat pump unit is no larger than a suitcase and adapts to ground installation or mounting on the side of the home.
