When a furnace blows cold air, it’s usually at the worst possible time, like the chilliest spell of the year or the night of an important family gathering. Furnaces are remarkably reliable and usually only an require an annual tune-up by an HVAC professional and regular filter changes by the homeowner. Normally, they'll provide a decade or more of trouble-free service before furnace replacement is required. When a furnace blows cold air, there may be a simple explanation or it may be a sign that something more serious has gone awry. That's when you need a service call from an HVAC professional to sort it out. Here are some of the possibilities:

Where central heating ducts aren’t installed, ductless heating or a portable heater are two viable solutions. In many cases, extending ducts to a new add-on or remodel in an existing home is financially prohibitive or just not worth the disruption of opening up walls and ceilings. Choosing between ductless heating or a portable heater involves drawing clear distinctions between the pros and cons of each.

How does a ductless mini-split heat pump work? Ductless technology takes the best of central heating and cooling, subtracts the ductwork, and delivers safe, reliable comfort at a higher efficiency than a central system. A ductless heat pump incorporates an outside coil and compressor to extract heat energy from outdoor air. This heat is transferred to refrigerant and conveyed indoors in a small conduit to one or more wall- or ceiling-mounted air handlers incorporating a coil. Hot refrigerant warms the coil and the heat is dispersed into the room by a blower fan. In summer, the system reverses and the coils trade functions. Indoor heat is extracted, transferred outside and dispersed into outdoor air. Ductless Heating Pros
Ductless System Cons

If you’ve ever laid awake at night listening to the sound of a furnace turning on and off repeatedly, you know how monotonous and annoying it can be. You may also know it’s wasting money and decreasing household comfort as well. A furnace operates at optimum efficiency when all components remain at the steady, proper operating temperature. When the system cycles on and off rapidly, the quick heating and cooling of components degrades efficiency. In addition, rapid short cycles cause abrupt temperature fluctuations instead of evenly heating the living spaces in your home.
Here are some possible reasons why your furnace is turning on and off too much:
A new furnace upgrade that wasn’t properly sized for the thermal requirements of your home will frequently short cycle, turning on and off rapidly. All new installations should be preceded by a load calculation performed by an HVAC professional to accurately match the output of the furnace to the heating needs of the house.
When the internal temperature of the furnace exceeds design limits, a safety sensor called a high-limit switch automatically shuts down the furnace. After the unit cools, the switch will allow the furnace to activate again and the pattern will recur.
Overheating in a furnace is often a consequence of inadequate airflow. The most common cause of low airflow is a clogged air filter. Filters should be changed according to the manufacturer’s recommended interval.
Another reason for excessive heat build-up inside the furnace is a blocked exhaust vent. Birds nests, leaves or other debris may clog the vent pipe from the exterior. A blocked vent not only causes overheating, it increases the risk of dangerous carbon monoxide gas infiltrating your home.
Because of the fire hazard and health and safety issues posed by an overheating furnace, homeowners who notice short-cycling should schedule a furnace inspection with a reputable HVAC contractor.
