As a homeowner or business owner, managing your HVAC system can be a bit of a balancing act. With rising energy costs and the demand for comfort year-round, it’s tempting to try fixing minor HVAC issues yourself. However, while DIY fixes might seem like a cost-effective option, they can sometimes lead to bigger problems, additional costs, or even damage to your system. Knowing when to call a professional HVAC contractor is crucial for maintaining a healthy, efficient system that keeps your home or business comfortable throughout the year.
At Advanced Cooling, we understand the importance of reliable heating and cooling systems, and our team has been providing expert HVAC services in Texas and Oklahoma since 2001. Whether it’s a residential repair or a commercial system issue, we’re here to help. Below, we’ll outline common HVAC issues, when it’s okay to try a DIY fix, and when to call an HVAC contractor.
Air Filter Replacement: DIY Friendly
When to DIY: Changing your HVAC system’s air filter is one of the simplest and most cost-effective maintenance tasks you can do yourself. Over time, air filters become clogged with dust, dirt, and debris, which can reduce your system’s efficiency and affect indoor air quality. Replacing the filter regularly (every 1-3 months, depending on usage) is an easy job that requires little expertise.
Why it matters: Keeping your air filters clean ensures that your HVAC system runs efficiently, reducing the workload on your system, extending its lifespan, and improving air quality in your home or business. Regular air filter changes also help lower your energy bills by maintaining good airflow.
When to Call an HVAC Contractor: If you’ve replaced your air filter but notice that the airflow is still weak, or if your system is making strange noises despite a fresh filter, this could indicate a deeper issue—such as a blocked duct or an issue with the blower fan. An HVAC contractor can assess the system and identify the root cause of the problem.
Thermostat Calibration: DIY Friendly
When to DIY: If your thermostat is inaccurate or malfunctioning, it’s often a simple matter of recalibration or replacing the batteries. If the system is not responding or seems to be off by a few degrees, recalibrating the thermostat can sometimes resolve the issue. You can also check for any loose connections or dirt that might be interfering with the system.
Why it matters: A faulty thermostat can cause your HVAC system to overheat or overcool your home, leading to energy waste. Fixing it promptly can help keep your energy costs under control and improve comfort.
When to Call an HVAC Contractor: If the thermostat is still malfunctioning after recalibration or battery replacement, or if you suspect issues with the wiring, it’s time to call an HVAC contractor. A professional can test and repair the thermostat or suggest upgrading to a more efficient model, such as a smart thermostat that helps save energy and improve system performance.
Clogged Condensate Drain: DIY Friendly
When to DIY: If you notice water pooling around your HVAC system or the indoor air handler, the condensate drain might be clogged. You can attempt to clear the drain by using a wet/dry vacuum to suck up any debris or using a cleaning solution to remove clogs. Some systems also have a secondary overflow drain, which can help prevent water damage.
Why it matters: A clogged condensate drain can cause water damage to your HVAC system or even your home. Regular maintenance of the drain ensures that the system operates efficiently and prevents mold growth or water leaks.
When to Call an HVAC Contractor: If the clog persists despite your efforts, or if you notice water damage around the system, it’s time to call an HVAC contractor. A technician can thoroughly clean and inspect the condensate drain to ensure there’s no hidden damage and that the system is draining properly.
Refrigerant Leaks: Call an HVAC Contractor
When to DIY: While checking refrigerant levels might be tempting, handling refrigerant should always be left to a licensed professional. Refrigerant is a critical part of your air conditioning system, and dealing with it improperly can cause severe system damage, health risks, and potentially violate environmental regulations.
Why it matters: If your air conditioner isn’t cooling properly or if there are warm spots in the house despite the system running, it could indicate a refrigerant leak. Refrigerant leaks also cause the system to work harder, leading to higher energy costs and potential damage to the compressor.
When to Call an HVAC Contractor: If you suspect a refrigerant leak, it’s essential to call an HVAC contractor immediately. A professional can locate and repair the leak, recharge the system with the correct amount of refrigerant, and ensure the unit is operating safely and efficiently.
Unusual Noises: Call an HVAC Contractor
When to DIY: You may be tempted to investigate strange noises coming from your HVAC system, but diagnosing the source of the sound can be tricky. For example, a rattling noise might indicate something as simple as loose panels or something more serious, like an issue with the blower motor or compressor.
Why it matters: Unusual noises, such as banging, grinding, or screeching, often signal a mechanical issue that can cause long-term damage if left unaddressed. While you can check for obvious issues like debris in the vents or loose parts, diagnosing complex mechanical issues requires a professional’s expertise.
When to Call an HVAC Contractor: If your HVAC system is making strange or loud noises that you can’t identify, it’s important to call an HVAC contractor as soon as possible. A technician can diagnose the problem and repair or replace any worn-out components before they cause more serious damage.
System Short Cycling: Call an HVAC Contractor
When to DIY: Short cycling, where the system turns on and off frequently, can sometimes be caused by a dirty air filter or thermostat issues, which can be easily fixed with some simple maintenance. If the problem is related to one of these issues, a DIY fix might resolve the issue.
Why it matters: Short cycling can waste energy and put unnecessary stress on your HVAC system, causing wear and tear on the components. Ignoring short cycling can lead to bigger, more expensive repairs down the road.
When to Call an HVAC Contractor: If short cycling continues after you’ve replaced the air filter or recalibrated the thermostat, it could be a sign of an issue with the compressor, refrigerant, or electrical components. An HVAC contractor can identify the root cause and repair the problem before it leads to system failure.
Complete System Failure: Call an HVAC Contractor
When to DIY: If your HVAC system completely stops working and you’ve already checked for simple issues like a tripped circuit breaker or thermostat problems, trying to fix the system yourself can be dangerous. HVAC systems are complex and require specialized knowledge to diagnose and repair.
Why it matters: A total system failure can be caused by a variety of factors, including electrical problems, compressor issues, or a malfunctioning motor. Without the proper training and tools, attempting a DIY fix can cause further damage or even void your warranty.
When to Call an HVAC Contractor: If your HVAC system stops working entirely and you can’t pinpoint the issue, it’s time to call a professional. An experienced HVAC contractor can diagnose the problem and offer an efficient solution, whether it’s a repair or a complete system replacement.
