A/C Repair in Scottsdale

A/C repair in Scottsdale can be an urgent requirement. Due to the nature of an air conditioner, problems often build and seem to appear out of the blue. Your home goes from wonderfully comfortable and pleasant to stuffy and uncomfortable almost instantly, with no respite from the sun's heat.

It can be extra frustrating when the HVAC unit stops working. When energy prices are high, the last thing you want to think about is the cost of A/C repair or replacement.

At 1-800-Plumber + Air, we offer the highest quality service at prices you can trust. Our handy guide on how to troubleshoot simple HVAC issues can assist you in locating the problem. In some cases, you might be able to perform the fix for yourself. If not, we're happy to lend a helping hand.

How to Troubleshoot HVAC Problems in Scottsdale

Before calling for a professional to help with A/C repair in Scottsdale, troubleshoot the entire system. It could be a simple issue that you can quickly fix yourself without needing to pay someone. We recommend that you start by looking at the more obvious HVAC equipment and work your way around to components that are hidden behind the scenes.

Diagnosing Your HVAC System

The HVAC system includes a thermostat, cold air return with a filter, a fan, ductwork, an air conditioner and a furnace.

First, check that there's power running to the HVAC system. Ensure the circuit breaker hasn't tripped on your home's service panel. The air conditioner and the furnace have separate switches on the circuit breaker. Turn off the A/C or furnace switch and wait for 30 seconds before turning it on again. If your Scottsdale home uses fuses, switch the main power off and check to see id any fuses need changing.

Next, check that your thermostat is switched on and working correctly. Many modern thermostats use batteries for power, try replacing the batteries and see if this solves the problem. If not, you might need to call in the help of a professional for A/C repair in Scottsdale.

Troubleshoot the Furnace

Say the thermostat is working, or it's switched on after a change of batteries — let's take a look at the furnace. Set the thermostat to the heat function and program it to 5 degrees Fahrenheit above room temperature. Find an open register and check to see if how air is blowing from it. If it's not working, turn the thermostat off and make sure that the furnace's panel door is closed.

Reset the entire furnace by pressing the reset button or turning off the gas. Wait for at least five minutes before switching the gas back on, turning on the thermostat and testing the heat again.

Test the Air Conditioning Unit Itself

In case the furnace is working just right, it's time to test the air conditioner. Set the thermostat to 5 degrees Fahrenheit below room temperature and check to see if cold air blows from a register. If there's no air, reset it at the circuit breaker. You might need to call in professionals for A/C repair in Scottsdale if it's still not working.

A/C Is Working but Not Cooling in Scottsdale

If the A/C unit turns on and the thermostat has the all-clear, but the system isn't pumping out cool air — the air condenser is probably blocked or dirty. Firstly, go outside and check that the outdoor unit isn't covered in dirt. Weeds might grow around the unit, or debris can build up and block the air circulation.

People in Scottsdale with pets or those who need to use their air conditioning more frequently should change the filter more often. Check the screen to make sure that it's clean. A dirty filter can prevent air from flowing through the unit properly, causing the evaporator coil to freeze. Pull the filter out and check if you can see through it. If not, a replacement filter might do the trick.

Otherwise, there could be an issue with the refrigerant or compressor. If this is the case, you'll need to call in an HVAC technician for A/C repair in Scottsdale.

Inside A/C Unit Is Running but Outside Isn't

It can be pretty confusing when you realize that the inside A/C unit is running, but the outside unit isn't. Bad capacitors, which store energy to power the fans, are the number one culprits. High temperatures like the ones we get in Scottsdale in the summer can cause a capacitor to fail.

If there's no air coming out of the vents, there's a good chance there's something wrong with the capacitors. An HVAC technician can replace them and check if there's any further damage to the compressors.

The compressor is a pump that puts high pressure on the refrigerant in the A/C system. These help the air to circulate properly through the system. Some of the signs of a faulty compressor include:

  • The unit is suddenly much louder than before

  • It starts clicking, rumbling or making other strange noises

  • There's a problem if the unit keeps tripping the circuit breaker or blowing fuses

  • If the compressor stutters or shakes when it starts, there's probably an issue

  • The aircon compressor won't turn on at all

Any of the above issues signal a severe problem with the HVAC unit. Don't worry, though; you can get expert A/C repair in Scottsdale at an affordable price.

A/C Not Blowing Air

These are the top seven reasons an AC unit might stop blowing air:

  1. Grimy Coils: Air conditioner coils are crucial because they help the AC unit to release heat. When they're dirty, they can't do their job correctly. These can lead to issues with airflow and prevent the whole HVAC system from working properly.

  2. Blockages or leakages: Ductwork is another essential part of the A/C unit. If any leaks or ducts get blocked, the unit can stop blowing air. In some cases, this might be caused by small animals nesting.

  3. System design flaws: If you've installed your system recently and there's no air blowing out. Check that everything is installed correctly — if you need help, call in the help of an HVAC professional.

  4. Condensor unit: Check the condenser unit's grate, but also make sure the area surrounding it is clean and free of debris. The unit must be able to access the air around it to produce adequate airflow.

  5. Registers and vents: If you've recently redecorated the house or moved the furniture around, you might have accidentally blocked an A/C vent. Go through the entire home and check that all the registers and vents aren't blocked.

  6. Filters: We can't stress the importance of clean, regularly changed filters enough. They remove contaminants and dust from the air, so it doesn't clog up the equipment. Clogged up filters can make the AC unit work extra hard and cause the coil to freeze up.

  7. Power problems: Hopefully, the reasons your A/C isn't working is a simple issue like a power outage. The grid is under immense pressure during Scottsdale summers due to everyone's need to stay cool in the hot weather. Blackouts are relatively frequent during heat waves, so check that there's power in the rest of the home.

Air Conditioner Isn't Turning On

If the A/C doesn't turn on at all, check to see if the condenser outside is running. Ensure you've set the thermostat correctly, and that the unit is plugged in.

Another great piece of advice is to read the HVAC unit manual from cover to cover. There might be a simple problem with the settings that you can fix yourself without any further assistance. If none of the above has worked, it might be time to call on the support of professional HVAC contractors for A/C repair in Scottsdale.
