The Temperature Does Not Stay at a Set Value
If the temperature does not stay at the value you set it to, there is likely a problem with your thermostat. Your thermostat could be old, worn, and outdated, or there could be a wiring issue. In any case, call your local HVAC company so a service technician can inspect and possibly replace your thermostat with a new model. You may want to opt for a smart thermostat because it learns your preferences and you can control it with an app you can download on your mobile devices.
You Hear Strange Sounds
If your HVAC system is working properly, you can expect to hear sounds as you turn the system on or off and as air flows through your vents. However, abnormal sounds, which include grinding, hissing, rattling, scraping, and squealing, could indicate a plethora of issues, including coolant leaks, leaky ductwork, or loose air conditioner components.
If you hear any abnormal sounds, call your local HVAC company right away. For example, if you live in Charleston, SC or a surrounding area, M&B Heating and Air can send an HVAC service technician to your home to inspect and repair your HVAC system.
Strange Smells Are Coming From Your Vents
If weird smells are coming from your vents, it could be due to mold growth or a wire burnout, among other things. When the wire installation insider your AC unit burns out, that can create a pungent odor. Musty smells usually indicate that mold is growing inside the unit or your ductwork. Whatever the cause, you should call in a professional to inspect your system and possibly clean out your ducts.
You Have Abnormally High Utility Bills
If your heating and cooling bills are abnormally high, it may be because your HVAC system isn't working efficiently. While you can do simple things, like cleaning or replacing your filters and removing debris and blockages from your outside AC unit and vents, you will need regular, professional HVAC maintenance.
An HVAC service technician should inspect your system at least once a year to make sure that the system is in top working order. The service technician can also check to see if there are coolant leaks, there is too little coolant, and whether there are leaks in your duct system. When your entire system is working properly and you have no leaks, the system requires less energy to run, which translates into lower utility bills for you.
If you want to enjoy your HVAC system for years to come, watch out for these warning signs, and schedule routine maintenance for your system. Not only will you be able to have consistent comfort in your home, but you will save money on your utility bills.
