Eliminating Hot And Cold Spots In Your Home
If you sometimes notice dramatic swings in temperature when your HVAC unit is running, you could be having hot and cold spots in various areas of your home. These hot and cold spots can make your home difficult to keep comfortable, and they often point to inefficiencies in your ductwork or problems with HVAC equipment sizing. Read on to learn what could be causing temperature inconsistencies in your home and what you can do to fix the problem.
Leaky air ducts
Leaky ductwork can be very problematic, as it can lead to the loss of huge amounts of conditioned air. This in turn makes balancing the temperature in your home nearly impossible, as some rooms will get less conditioned air than others. Leaks in the ducts also cause your air conditioning unit to work extra hard, leading to possible malfunctions.
If you have an older home, leaks in your ducts could be quite plausible. Having an HVAC contractor inspect the ducts for signs of damage such as holes, cracks, and loose connections can help improve the efficiency of your AC unit and prevent pollutants such as pollen and dust from contaminating your indoor air.
Exposed ducts in the crawlspace, attic, or basement are especially prone to air loss, leading to cold/hot spots in certain rooms. Other signs that your ducts may need sealing include excessive levels of humidity in your home, rooms that regularly feel stuffy, and unreasonably high energy bills.
Poorly insulated/sized ductwork
Typically, air ducts that have eroded insulation can contribute to the loss of heated or cooled air, making your HVAC unit deliver uneven temperatures across the home. You can inspect your ducts for missing insulation, especially in the crawlspace, basement and garage where air loss is often extreme. HVAC contractors can also come in and perform an infrared duct inspection to reveal areas with insufficient insulation.
Improperly sized ducts that aren't matched to the needs of your home could also lead to hot/cold spots and general HVAC inefficiency. The poor duct sizing and design can cause inadequate air flow that can make your AC unit less effective and compromise your comfort.
If you suspect that your ducts are too small for your home, consider calling in duct repair experts to measure and fit your heating and cooling unit with the right size of ducts. If the ducts are correctly sized but hot/cold spots are still present, then the HVAC unit may not be the appropriate size for the square footage of your home.
