If your HVAC system needs frequent repairs or your Danielsville, Pennsylvania, home is always too hot or too cold, you could need an upgrade. Even with regular maintenance, you’ll eventually need to replace your system. Paying for a repair is usually cheaper at first, but upgrading your system may be less expensive in the long run. Avoiding annoying breakdowns is also more comfortable and convenient. Upgrade your HVAC system when it gets older or when you notice poor indoor air quality, rising bills, or increased noise.

An Older Unit

You should replace your older heater or air conditioner with a newer, more reliable model before you have multiple inconvenient breakdowns, that could add up to significant repair costs. Most HVAC systems last from 10 to 15 years, and many older models use a refrigerant called R-22 that harms the ozone layer. Newer systems use a more environmentally friendly refrigerant called R-410A. R-22 is expensive and difficult to find, as are many parts for older systems.

This makes upgrading your HVAC system a much better idea than repairing an old unit. There are several tax credits available for switching to R-410A. Also, upgrading your system keeps old, worn wiring from becoming a fire hazard.   

Poor Indoor Air Quality

Even if you change your HVAC system’s air filter once per month, your heater or air conditioner could lose its ability to get rid of pollen, dust, dirt, mold, pet dander, and other pollutants in your indoor air. Without enough ventilation, contaminants can accumulate. Some types of mold contain mycotoxins that make asthma and other respiratory problems worse, and chemicals in many air fresheners and cleaners can also cause health problems.

Since many older systems can’t dehumidify homes well, mold could grow on ceiling tiles, underneath wallpaper, in carpeting, and almost anywhere else in your home. Some people are allergic to mold, pet dander, dust mites, or other common household substances. Poor indoor air quality can lead to unpleasant musty smells, sinus troubles, fatigue, and more. Have your ductwork and your HVAC system inspected by a professional if you or your family notices any of these problems. You can also add a UV air purifier to your HVAC system. These devices can’t eliminate all pollutants, but they can use lamps that produce ultraviolet light to kill mold, bacteria, and viruses.

Increasing Utility Bills

Like most appliances, HVAC systems become less efficient when they get older. If you notice increasing utility bills along with overly warm or drafty spots in your home or less cool air in general, your system could be less efficient than current systems or even need expensive repairs. Gaps in your insulation or leaky ductwork can also increase your bills. An experienced HVAC professional will let you know when upgrading your HVAC system will be less expensive than making repairs.

For low energy bills after you upgrade, choose a heater or air conditioner with a high SEER or Seasonal Energy Efficiency Ratio. Many newer HVAC systems take advantage of new technologies like solar power, geothermal energy, and several types of heat distribution systems to conserve energy.

Lots of Noise

Your HVAC system should be relatively quiet, but many older models make loud humming sounds. Squealing or screeching could be a minor problem like a worn belt or something more serious like a malfunctioning motor. You can keep your HVAC system working longer by having it maintained by a professional at least once per year. Make sure to have your system’s oil and other fluids checked and replaced if needed.

Loud rattling, thumping, clanking, or banging noises are also signs of a problem with the blower assembly or the motor. Call a professional immediately if you hear loud rattling or banging.
