HVAC Repairs: When to DIY and When to Call the Accu-Temp Pros
Living in Central Texas means your HVAC system works overtime. Between our scorching summers and unpredictable weather swings, your air conditioning and heating system gets put through the wringer year-round. When something goes wrong, you’re faced with a choice: roll up your sleeves and try to fix it yourself, or call in the professionals?
We get it – nobody wants to spend money they don’t have to. But when it comes to HVAC repairs, knowing when to DIY and when to call the pros can save you money, keep your family safe, and prevent small problems from turning into expensive disasters.
The Safe DIY Zone: What You Can Handle
Let’s start with the good news – there are plenty of HVAC maintenance tasks you can tackle on your own. These simple jobs don’t require special tools or technical expertise, and they’ll keep your system running smoothly between professional visits.
Air Filter Changes: Your First Line of Defense
This is HVAC maintenance 101, but you’d be surprised how many Central Texas homeowners forget about their filters. With all the pollen, dust, and debris that comes with our climate, your air filter works harder than most. A clogged filter makes your system work overtime, drives up energy bills, and can lead to bigger problems down the road.
Check your filter monthly and replace it every 1-2 months, depending on usage and air quality. If you have pets or someone in your home has allergies, you might need to change it more frequently. It’s a simple task that takes less than five minutes and costs under $20, but it can prevent hundreds of dollars in repairs. Read more about filter changes here.
Basic Thermostat Troubleshooting
Before you panic about a broken AC, double-check your thermostat settings. Make sure it’s set to “Cool,” that the temperature is set lower than the current room temperature, and that it’s actually working. If you have a battery-powered thermostat, try replacing the batteries – it’s amazing how often this simple fix solves the problem.
For programmable or smart thermostats, check if someone accidentally changed the schedule or if there’s a software glitch. Sometimes a simple reset can get things back on track.
Clearing Debris and Basic Cleaning
Your outdoor unit needs room to breathe. Take a look around your condenser unit and clear away any leaves, grass clippings, or debris that might be blocking airflow. You can also gently hose down the unit to remove dirt and pollen buildup – just make sure to turn off the power first.
Inside, keep your vents and registers clean and unobstructed. Move furniture, curtains, or other items that might be blocking airflow. Clean vents with a vacuum or damp cloth to remove dust buildup. Make sure the vents are open. Read more tips here.
Simple Drain Line Maintenance
Your AC’s condensate drain can get clogged with algae and debris, especially in our humid Texas climate. If you notice water pooling around your indoor unit, you might have a clogged drain. You can try flushing the drain line with a mixture of water and vinegar, but be careful not to force anything or use harsh chemicals. Learn more about this process here.
When to Call the Accu-Temp Pros
Now for the important part – knowing when to step back and let the professionals handle things. Some repairs might seem simple, but they involve safety risks or complex systems that require specialized knowledge and tools.
Electrical Issues: Never Worth the Risk
If your HVAC system has electrical problems – flickering lights when it starts up, burning smells, or complete power loss – don’t try to fix it yourself. Electrical work requires proper training and safety equipment. One wrong move could result in electrocution, fire, or expensive damage to your home’s electrical system.
Our Accu-Temp technicians are licensed and trained to handle all electrical aspects of HVAC systems safely. We have the proper tools and experience to diagnose and fix electrical problems without putting you or your family at risk.
Refrigerant Problems
If your AC isn’t cooling properly despite a clean filter and proper thermostat settings, you might have a refrigerant leak or low refrigerant levels. Refrigerant is a controlled substance that requires special certification to handle, and working with it improperly can be dangerous and illegal.
Signs you might have refrigerant issues include ice buildup on your unit, hissing sounds, or warm air coming from your vents even when the system is running. These problems require professional diagnosis and repair.
Compressor and Motor Issues
Your HVAC system’s compressor and motors are complex, expensive components. If you’re hearing unusual noises – grinding, squealing, or banging sounds – it’s time to call in the pros. These components require specialized knowledge to diagnose and repair properly.
Trying to fix compressor or motor problems yourself can lead to complete system failure, which means replacing the entire unit instead of just repairing a component.
Gas Line and Heat Exchanger Problems
For homes with gas heating systems, any issues with gas lines, heat exchangers, or combustion components should always be handled by licensed professionals. Gas leaks can be deadly, and improper repairs can lead to carbon monoxide poisoning.
If you smell gas, hear hissing near your unit, or notice yellow flames instead of blue in your furnace, turn off your system immediately and call for professional help, including the gas company if you believe you have a gas leak.
The Hidden Costs of DIY Gone Wrong
While DIY repairs might seem like money-savers, they can actually cost you more in the long run. Here’s why professional service often makes more financial sense:
Warranty Protection
Most HVAC manufacturers require professional installation and maintenance to keep warranties valid. If you attempt DIY repairs on a system under warranty and something goes wrong, you might void your coverage entirely. That could mean paying full price for expensive component replacements that would have been covered.
Preventing Bigger Problems
HVAC systems are interconnected. A small problem in one area can cause cascading issues throughout the system. Professional technicians can often spot these potential problems early and fix them before they become expensive repairs.
When you try to fix something yourself and make a mistake, you might create additional problems that cost more to fix than the original issue.
Energy Efficiency
Improperly repaired HVAC systems often run inefficiently, leading to higher utility bills. Professional repairs ensure your system operates at peak efficiency, saving you money every month on energy costs.
Time and Frustration
DIY repairs can take hours or even days, especially if you need to research procedures, order parts, or start over when something goes wrong. Professional technicians can typically complete repairs quickly and efficiently, getting your comfort restored fast.
