Basic Troubleshooting for HVAC Repair

Now that you’ve got the basics of HVAC maintenance down, let’s tackle some common problems you might encounter with your system. Remember, these tips are for minor hiccups – if things get too complicated or you’re unsure, it’s always best to call in the experts at Morehart Air Conditioning and Heating.

Scenario 1: Your AC is Blowing Hot Air (Not Cool!)

The Arizona heat is brutal enough without your AC turning on you! If your air conditioner is blowing hot air instead of cool relief, don’t panic. There are a few common culprits you can check yourself before calling in the pros:

• Thermostat: First things first, make sure your thermostat is set to “cool” and the temperature is set a few degrees lower than the current room temperature. It sounds obvious, but you’d be surprised how often a simple setting adjustment does the trick!

• Filter: A dirty air filter is a common cause of AC woes. It’s like trying to breathe through a straw – your system has to work harder, and it just can’t keep up with the demand for cool air. Swap out that dirty filter for a fresh one and see if that makes a difference.

• Refrigerant: If your AC is low on refrigerant (the stuff that makes the cooling magic happen), it won’t be able to do its job. Unfortunately, this isn’t something you can fix yourself. If you suspect a refrigerant leak, call in the experts at Morehart Air Conditioning and Heating to diagnose and repair the problem.

• Breaker: Before you call anyone, double-check your electrical panel. If the breaker for your HVAC system has tripped, simply reset it. Easy peasy!

• Condenser coil: The outdoor unit’s condenser coils can get pretty grimy, especially in our dusty desert climate. This buildup can prevent the coils from releasing heat, causing your AC to struggle. Gently hose off the coils (remember to turn off the power first!) and see if that improves things.

Remember, these are just basic troubleshooting steps for HVAC repair. For more serious issues or if you’re unsure about any steps, don’t hesitate to contact Morehart AC & Heating for professional assistance.

Scenario 2: Your Furnace is Giving You the Cold Shoulder

Brrr, a cold house in the winter is no fun! If your furnace isn’t producing any heat, here are a few things to investigate before calling in the cavalry:

• Thermostat (again!): Just like with your AC, make sure your thermostat is set to “heat” and the temperature is set a few degrees higher than the current room temperature.
• Pilot light problems (gas furnaces only): If your furnace has a pilot light, make sure it’s lit. If it’s out, try relighting it according to the instructions on your furnace. Still no luck? Call Morehart Air Conditioning and Heating – it could be a gas supply issue or a problem with the thermocouple.
• Filter: Yep, that pesky air filter can cause problems with your heating too. A clogged filter restricts airflow, making it harder for your furnace to do its job. Swap it out for a new one and see if that helps.
• Gas gauge: If you have a gas furnace, make sure the gas valve is open. If it’s closed, your furnace won’t have any fuel to burn.
• The flame: Take a peek at the furnace flame (if it’s safe to do so). If it’s weak, uneven, or flickering, it could indicate a problem with the burners or gas pressure. This is another situation where it’s best to call in the professionals.

Scenario 3: Weird Noises From Your HVAC Unit

If your HVAC system starts sounding like a scene from a horror movie, it’s time to investigate. Those creaks, groans, and bangs could be trying to tell you something important. Here’s a breakdown of some common HVAC noises and what they might mean:

• Rattling: This usually means something’s loose. It could be a screw that needs tightening, a panel that’s come undone, or even debris rattling around in your ductwork. If you’re feeling adventurous, you can try to locate and tighten any loose screws yourself. Just be careful not to overtighten them! If the rattling is coming from inside the ductwork, it’s best to call in a professional to investigate the HVAC repair needs.
• Squealing: This high-pitched noise often indicates a worn-out belt or bearing. These components are essential for the smooth operation of your system, so it’s important to address this issue promptly. Unfortunately, replacing belts or bearings usually requires specialized tools and expertise, so it’s best to leave this HVAC repair to the pros at Morehart AC & Heating.
• Grinding: A grinding noise is often a sign of trouble with your HVAC motor. It could mean the bearings are worn out, the motor is overloaded, or there’s another mechanical issue. This is not a DIY repair – call in the experts to diagnose and fix the problem before it causes further damage.

Remember, safety first! If you’re not comfortable working with electrical or mechanical components, don’t attempt any repairs yourself. Call Morehart AC & Heating and let our experienced technicians handle your HVAC repair needs.
