When it comes to your home's air conditioner, you probably don't give much thought to it as long as it is cooling off your home during the summer. However, when you experience a breakdown during the dead middle of what feels like the hottest summer in years, you will wish that you had thought more about A/C maintenance. So, to avoid an unnecessary breakdown, you should watch out for warning signs that your HVAC unit is giving you that are signaling a potential breakdown in the foreseeable future. When these signs arise, it is time to give a professional HVAC technician in your area a phone call for an inspection. Here are three issues that you may encounter that would warrant that phone call:

1. Spike in Your Utility Bills

As long as your air conditioner is operating normally, you won't notice a significant change in your utility bills. However, when you're A/C's efficiency starts to falter, your utility bills will usually increase even when your family's usage hasn't changed. One possible problem may be with the fan, which could cause the unit to operate longer than truly necessary.

2. Strange, New Noises

As a general rule, your air conditioning unit should only make a slight humming noise when it is operating under normal conditioners. Now, if you begin to notice that your air conditioner is making a strange, new noise that it normally doesn't make, then it could be a sign of trouble. Loud rattling can be a sign that there is a problem with your ducting or that a part inside the air conditioner has become loose. Squealing noises are often the result of moving parts needing additional lubrication.

3. Difficulty Acquiring a Preferred Temperature

When you set your thermostat to a certain temperature, your air conditioner should kick on shortly after and reach that temperature pretty quickly and then switch off. However, if you notice that it is taking a considerable amount of time to reach your desired temperature, it is time to call in a professional. There may be a problem with the thermostat, or it may be a much deeper problem that needs to be inspected and repaired.

If you are currently experienced any of the aforementioned issues, it is important that you call an air conditioning expert from a company like D & R Service Inc immediately. Just remember: the sooner that you have your unit inspected, the sooner it can be repaired and you can get back to experiencing a cooler home.
