With temperatures high and extreme weather patterns it’s important to maintain the use and longevity of your HVAC system. We understand the value of living comfortably and with peace of mind, especially on days with extreme high temperatures. Not having a working HVAC system in the summer in Texas can be very dangerous. In Part II of this article we’ll discuss some of the issues that may come up with your HVAC unit this summer.
1. Fan Problems
Problem: Your HVAC system has fans that circulate air through your air conditioning system. Fans can become damaged with worn belts, motor failure, bent blades, etc. If your HVAC fan has any issues it can lead to your system overheating.
Solution: Make sure to have your fans regularly checked for any issues. If it is making any abnormal noises or you notice your HVAC system has a reduction in airflow you will need to contact a professional. Have your registered HVAC technician inspect your unit and do any necessary maintenance.
2. Electrical Issues
Problem: Your HVAC system has many electrical components like capacitors, contractors and wiring. These parts can wear down over time or become damaged. If your HVAC system is having electrical issues you may notice it short cycling, not starting, or shutting off completely.
Solution: Having your HVAC system regularly maintained and inspected by a local registered HVAC technician can prevent any electrical issues. If these issues are happening too often your HVAC technician may recommend an upgrade to your system.
3. Frozen Evaporator Coils
Problem: Evaporator coils work to absorb the heat coming from inside your home. While it might seem odd, these coils can actually freeze. This could be caused by poor refrigerant levels, poor airflow, or a bad blower fan. This reduces the cooling efficiency of your HVAC system.
Solution: If the evaporator coils are frozen keep your system turned off so they can take time to thaw. Once thawed, check to make sure you're getting proper air flow throughout your home/space. If the problem still occurs you’ll need to contact your HVAC technician to have it fixed or replaced.
4. Uneven Cooling
Problem: If there is any uneven cooling in your home/space there could be issues with your ductwork. This could be due to blockages of debris, dust, animal nests, etc. You could also have an HVAC system that may not be suitable for the size of your space, which leads to the system cooling unevenly.
Solution: If there is uneven cooling, have a professional come look at your HVAC system. They can inspect your ductwork, and clean out your ventilation system if needed. If your system is the wrong size for your space you may want to consider upgrading to something more suitable.
5. Short Cycling
Problem: If your unit suddenly turns on and off without completing its full cooling cycle you may have an issue of short cycling. Short cycling can lead to an overuse of your HVAC system leading to higher energy costs.
Solution: If your unit is short cycling there could be a variety of underlying issues causing this to happen. Have your local HVAC professional inspect your system to see what the underlying cause of the short cycling is. You will most likely need to have maintenance done and worst case you may need to replace your unit.
It’s important to stay vigilant and address concerns with your HVAC system during the summer months. Worst case scenarios could lead to your cooling unit to not work in extreme heat temperatures, which can be dangerous. If you have any questions, reach out to us at Air-Mart AC & Heating.
