Many homeowners don't think much about their heating and cooling systems until something bad happens. Regular maintenance is essential for a well-functioning, energy-efficient, HVAC system. If you haven't had your HVAC system tuned up in a while, there are a few signs that it's time to schedule your maintenance appointment. Knowing these warning signs can be useful in determining if it's time to take necessary steps to guarantee that your heating and cooling systems continue to operate at top efficiency. These signs are outlined below.

1. High Energy Bills

It's common to observe an increase in your monthly energy bill if you operate your heater or air conditioner frequently throughout the middle of winter or the peak of summer. Higher energy expenditures are unavoidable consequences of using your HVAC system. If you see unusually high prices or unexpected spikes in your energy bill, your system isn't performing as well as it should. It should not cost an excessive amount to keep your house warm, and a well-functioning system should not result in unexpected rises in your bill. If you notice any significant changes in your monthly energy bills, it's time to get some help. AC repair companies have the knowledge and expertise you need to get your system running efficiently again. In fact, updating your HVAC unit may even lead to further cost savings. According to the U.S. Department of Energy, updating your HVAC unit may reduce energy consumption by 50% for electricity and 10% for gas.

2. Unusual Noises Coming From Your HVAC System

Don't overlook the weird sounds coming from your air conditioner or the peculiar hissing from your furnace. These and other loud, unexpected noises may be signs of a larger problem. It's better to treat them as soon as possible to avoid significant breakdowns and costly AC or heater repairs. While they may appear small, odd noises from your HVAC system are nearly always indicators of a problem. This is why you should schedule an appointment for a tune-up as soon as possible.

3. Your System Turns On and Off Unexpectedly

If your system is turning on and off unexpectedly, you'll need to contact an HVAC repair company. HVAC specialists refer to this phenomenon as "short-cycling." When a system short-cycles, it generates hot or cold air as needed. However, due to a malfunction, it turns off shortly after turning on. Unless an HVAC technician helps you address and correct the problem, your system will continue to short-cycle. A common cause of this issue is if your air conditioner is short on coolant. This could also be caused by the air filter in the furnace if it is clogged.

If you notice any of these signs, it's time to think about contacting your local HVAC repair company. AC repair companies offer the inspection, maintenance, or repairs that you need. Do you need an HVAC expert? Reach out to Williams Mechanical Service Inc today!
