Protect Your HVAC System

As soon as I purchased my first home, I realized that it was going to be difficult to take care of all of the appliances. I was worried that some components would fail or that others would simply suffer from neglect. Unfortunately, I had no idea what to do in order to avoid these types of problems. To ward off my worries, I decided to hire a professional HVAC contractor who could help. I was able to find an incredible business in my area who really cared about their products and services. They taught me how to look for problems and how to troubleshoot a lagging system. Check out this blog for more information about protecting your HVAC system.

3 Signs You Need To Call An HVAC Specialist For Your Air Conditioner

Ricardo Sanchez

As summer months approach, it is important to have your air conditioning system working at optimal levels. If your air conditioning unit shows signs of disrepair, it is best to have them addressed immediately. Here are a few signs that you should contact an HVAC specialist: 


When your air conditioner is operating properly, it may release a low humming sound. The sound is often due to the quiet rush of air through your home ventilation system coupled with the low vibrations of your system. However, if you are noticing new noises coming from your unit, there may be a problem.

Rattling noises may indicate that one of your system parts has become loosened. In addition, a component of your unit may no longer be in place. The vibrations of the system can sometimes loosen screws and cause a component to detach. Your system would need to be inspected by a professional to determine the cause of the unusual noises that you are noticing.

Warm Air

If your system appears to be operating and no noises are apparent, there may still be a problem if the temperature of the air blowing from your unit is too warm. Adequate levels of refrigerant are needed to properly cool the air that climatizes your home. If refrigerant levels become too low, additional refrigerant should be added by an HVAC professional. The technician will know the proper type of refrigerant that is required by your system. In addition, he or she will understand the pressure levels that need to be maintained.

No Response

If your air conditioning system does not respond to new settings on your thermostat, the system needs to be serviced. This failure of an air conditioning unit to respond to a new temperature setting could be due to a broken thermostat, wiring problems or even a failing compressor.

An HVAC professional can inspect the unit to determine the exact cause of its failure to respond. Replacing a faulty thermostat is relatively inexpensive. However, if the unit is old and the compressor has failed, the technician may recommend that a new air conditioning unit is installed. Even though the upfront expense of a new unit may seem high, new air conditioning systems are often much more energy-efficient than their older predecessors. Thus, you could incur substantial savings on your cooling costs.

If you are concerned about the state of your air conditioning system and would like to have it inspected, schedule an appointment with an HVAC specialist (such as one from Shenandoah Air Conditioning & Heating) in your area.
