Air Experts Heating And Air Conditioning

One of the most frustrating experiences for any homeowner is waking up to a house that's either much too hot or much too cold. When your Air Experts Heating and Air Conditioning system isn't performing as expected, it can disrupt your comfort and lead to unnecessary stress. Let's explore a common issue: lack of heating or cooling, and how you can troubleshoot it before calling for professional help.

Step 1: Initial Checks – The Obvious (But Essential)

Before diving into more complex diagnostics, let's cover the fundamental checks. Often, the solution is simpler than you think.

Is the System Switched On?

This may sound trivial, but it's surprising how often this is the culprit. Ensure the thermostat is set to "Heat" or "Cool" and that the desired temperature is significantly higher or lower than the current room temperature. For example, if it's winter and your house is 65°F, set the thermostat to at least 68°F to initiate the heating cycle. In summer, reverse the process.

Also, verify that the system switch (often found near the furnace or air handler) is in the "On" position. Someone might have accidentally switched it off.

Check the Circuit Breaker

A tripped circuit breaker is another common cause. Locate your electrical panel and look for any breakers that are in the "Off" or "Tripped" position. Reset the breaker by first switching it completely to the "Off" position and then back to "On".

Important Safety Note: If the breaker trips again immediately, do not keep resetting it. This indicates a more serious electrical problem, and you should contact a qualified electrician or Air Experts immediately.

Inspect the Air Filter

A dirty or clogged air filter is a major contributor to HVAC problems. It restricts airflow, forcing your system to work harder, reducing efficiency, and potentially causing it to overheat or freeze up.

Locate your air filter (typically in the air handler or furnace) and remove it. Hold it up to the light. If you can barely see through it, it's time for a replacement. Replace it with a new filter of the correct size and type. Air Experts recommends checking your filter monthly and replacing it every 1-3 months, depending on usage and air quality.

Step 2: Thermostat Troubleshooting

The thermostat is the control center of your HVAC system, so ensuring it's functioning correctly is crucial.

Battery Check (for Digital Thermostats)

Many digital thermostats rely on batteries. Check the battery level and replace them if they're low or dead. Low batteries can cause erratic thermostat behavior, including incorrect temperature readings or failure to communicate with the HVAC system.

Thermostat Settings and Programming

Review your thermostat's programming to ensure it's set up correctly. Make sure the current time and day are accurate. Incorrect settings can lead to the system running at unexpected times or not running when you need it to.

Also, check for any temporary overrides or "hold" settings that might be preventing the system from following its regular schedule.

Thermostat Location

Believe it or not, the location of your thermostat can impact its accuracy. Avoid placing thermostats in direct sunlight, near drafts, or close to heat-generating appliances like lamps or TVs. These factors can cause the thermostat to read the temperature inaccurately, leading to inefficient heating or cooling.

Step 3: Outdoor Unit Inspection (Air Conditioner Only)

If you're experiencing cooling issues, the outdoor unit (condenser) is a key area to investigate.

Visual Inspection

Check for any obvious obstructions around the outdoor unit, such as overgrown vegetation, debris, or snow/ice buildup. Clear away any obstructions to ensure proper airflow. Airflow restriction can cause the unit to overheat and shut down.

Coil Inspection

The condenser coils are responsible for releasing heat. Inspect the coils for dirt, leaves, or other debris. You can gently clean the coils using a garden hose with a spray nozzle. Be careful not to bend the delicate fins. Avoid using high pressure, as it can damage the coils.

Important Safety Note: Turn off the power to the outdoor unit at the breaker before attempting any cleaning.

Fan Operation

When the air conditioner is running, the fan on the outdoor unit should be spinning. If the fan isn't running, it could indicate a motor problem or a faulty capacitor. This typically requires professional repair.

Step 4: Indoor Unit Inspection (Furnace or Air Handler)

The indoor unit plays a crucial role in distributing heated or cooled air throughout your home.

Blower Motor Function

Listen for the blower motor to start when the system is activated. If you don't hear the blower motor running, it could indicate a problem with the motor itself, the capacitor, or the control board. This usually requires professional diagnosis and repair.

Check for Blocked Vents

Ensure that all supply and return vents in your home are open and unobstructed. Blocked vents restrict airflow, reducing the efficiency of your system and potentially causing it to overheat.

Inspect the Flame Sensor (Gas Furnaces Only)

Important Safety Note: This step applies only to gas furnaces. If you are not comfortable working with gas appliances, skip this step and contact Air Experts.

The flame sensor is a safety device that detects the presence of a flame. If the flame sensor is dirty or malfunctioning, it can cause the furnace to shut down prematurely. Locate the flame sensor (it's typically a small metal rod near the burner) and carefully clean it with fine-grit sandpaper or steel wool.

If the furnace continues to shut down after cleaning the flame sensor, it could indicate a more serious problem with the gas valve, igniter, or control board, requiring professional attention.

When to Call Air Experts Heating and Air Conditioning

While many HVAC issues can be resolved with simple troubleshooting steps, some problems require the expertise of a qualified technician. Here's a breakdown of when to call Air Experts:

Electrical Problems: If you suspect any electrical issues, such as a tripped breaker that repeatedly resets, do not attempt to diagnose or repair the problem yourself. Contact a qualified electrician or Air Experts.
Gas Leaks: If you smell gas near your furnace or any other gas appliance, evacuate your home immediately and call your gas company and Air Experts from a safe location.
Refrigerant Leaks: Refrigerant leaks can be harmful to the environment and can reduce the efficiency of your air conditioner. If you suspect a refrigerant leak (e.g., ice buildup on the coils, hissing sound), contact Air Experts.
Compressor Problems: The compressor is the heart of your air conditioner. If you suspect a compressor problem (e.g., unusual noises, lack of cooling), contact Air Experts.
Control Board Issues: The control board is the brain of your HVAC system. If you suspect a control board issue (e.g., erratic system behavior, error codes), contact Air Experts.
Major Component Failures: If you suspect that a major component, such as the blower motor, heat exchanger, or condenser fan motor, has failed, contact Air Experts.
Persistent Problems: If you've tried the troubleshooting steps outlined above and your HVAC system is still not working properly, it's time to call Air Experts.
Lack of Technical Expertise: If you're not comfortable working with electrical or mechanical components, it's always best to err on the side of caution and contact Air Experts.

In summary, if you encounter any issues that involve electrical components, gas leaks, refrigerant leaks, or complex mechanical problems, it's crucial to contact Air Experts Heating and Air Conditioning for professional assistance. Attempting to repair these issues yourself can be dangerous and could potentially void your warranty.
