The most common of HVAC problems tend to be the thermostat. It might be something as simple as having it set to the auto setting, instead of on. There is also the chance that someone else changed it or you changed it yourself and forgot. You want to make sure that the thermostat is one and the settings are as you like them. If there is something wrong that is causing you HVAC problems, this will be the first thing they ask you about. They will want to know if you checked the settings and how the system is acting in response to them. This will rule out any user error.

Needs Coolant

Every now and then you want to check the coolant level and make sure it isn’t too low. If your thermostat is working properly and properly set, you might just be out of coolant. A leak causes big  HVAC problems for you, and you will run out of coolant faster than you should. You need to repair and clean the leak immediately. It is worth remembering that Freon is a coolant that has been

It is worth remembering that Freon is a coolant that has been regulated heavily by the Environmental Protection Agency (EPA). This is because it is considered an Ozone depleting compound, so it isn’t something you want to have laying around. Freon is being phased out, which began in 2010. However, there are still functioning units that were manufactured before the change and are still in use. Those which are functioning properly can still be recharged, but only by a licensed technician. It’s sale also requires a license. Units which are no longer functioning have to be replaced with newer models. You can read more about this here.

General Maintenance Skipped

One of the major causes of system failure is skipping maintenance. Major repairs and maintenance are essential to the function of your unit. HVAC problems happen when you slip in these basic tasks, changing the filter being an example. You also want to make sure that the unit is free of debris while doing so. You want to replace these filters every one to three months. Remember that the more you use your air, the sooner it will build residue. A filter that needs to be cleaned causes the system to work harder, causing HVAC problems. You should also have your system inspected every year, just to make sure that everything is working properly.

Sensor Malfunction

The sensors in thermostats communicated with the HVAC unit about the temperature. It measures the air in the home and dictates whether the unit needs to raise or lower the temperature. Sometimes sensors can fall or shift out of place. This can mean improper temperature readings and malfunctions. If you think you might have this problem, you can open the case of the unit and take a look at the control panel. If you see the sensor is touching the evaporating coil, you can move the wire to the sensor. Once you have closed it up, try checking to see if that fixes your HVAC problems.

Component Failures

There are plenty of components that comprise your air conditioning unit. Facets like the blower, compressor, fan, and condenser work the functions that cool and hear your home. These parts wear and need replacement over time. Sometimes it isn’t too long, and it just depends on the quality of the component and how hard it is working in your system. If you don’t maintain your unit and run it constantly, it may be sooner than later. When you schedule your annual check, these should be things they look at. It is also a good idea to ask about the price of these components and if there are generic replacements available. Sometimes there are even used, or knock-0ff items that can be used in its place.

Drainage Block

The pipes that drain your unit can cause HVAC problems, too. It can become blocked with leaves, dirt or other debris. When they are unable to drain properly, water flows into the drain pan. However, once this fills the water can overflow and cause water damage. There is also the unavoidable issue of mold or algae. You can pour vinegar in the areas they grow, but this will not prevent it from ever happening. It will only deter and slow down the process. This is something you should ask about during your yearly inspection and be conscious of. Make sure that you ask everything they look at and about proper maintenance. You might even want to create a checklist, to make sure that you are keeping up with the maintenance and in a timely fashion. You can start with all of your questions here.
