HVAC Repairs You Should Never Attempt to DIY 

We know that many homeowners are avid DIYers, but any kind of HVAC maintenance should be left to the professionals. While there are YouTube videos that can teach homeowners how to do almost anything, HVAC maintenance can be dangerous if not done properly.  

Our team at Integrity Home Solutions outlines HVAC repairs you should never attempt to DIY, plus a few that you can tackle on your own!  

Why Leave HVAC Repairs to the Pros  

You shouldn’t try to DIY HVAC repairs because: 

  • HVAC technicians use specialized tools and equipment for restoration and maintenance 
  • From natural gas to high electrical voltage, there are many hazards involved in HVAC repairs 
  • You could endanger the safety and well-being of everyone that lives inside your house 
  • Attempting DIY fixes could cause your air conditioner or furnace to operate inefficiently  
  • You may end up voiding your system’s warranty  

HVAC Repairs that Should be Left to HVAC Professionals  

Don’t attempt to do the following HVAC repairs:  

#1. Smart Thermostat Installation  

Unfortunately, even the smallest, most seemingly easy task, such as installing a smart thermostat, should be done by a professional HVAC tech.  

Before even buying a smart thermostat, we recommend asking an HVAC tech to ensure that your system is compatible. We recommend this because some older HVAC systems are not equipped to properly communicate with newer smart thermostats.  

Further, the average homeowner should not try to change their thermostat due to the electrical wiring involved. Wiring can sometimes be loose or frayed, which can cause all kinds of problems for someone who is not well-versed in electricity. In these cases, the electrical wires need to be fixed before installing the smart thermostat, and many homeowners are not equipped to do so.

#2. Cleaning the Outdoor Condenser 

Just because your AC unit’s outdoor condenser has a metal cage around it doesn’t mean that it isn’t fragile. The coils inside are quite delicate and should be treated as such.  

Many homeowners think that they can just spray the outside of the condenser with the hose and be done. But unfortunately, spraying the outside of the condenser with water can damage the condenser coils, which in turn, damages your system.  

#3. Refrigerant Leaks 

If your AC is constantly running, but your house isn’t cool, your HVAC system may be low on refrigerant, also called freon or coolant.  

But you should never attempt to fix, replace, or top off HVAC refrigerant on your own. HVAC refrigerant is toxic and should only be handled by an HVAC professional like our techs at Integrity Home Solutions!    

#4. Testing Electrical Components 

The indoor and outdoor AC units are made up of many electrical components including relays that connect to several electrical parts, such as: 

  • Compressors 
  • Motors 
  • Capacitors 
  • Transformers 
  • A circuit board 
  • Thermostat 
  • And more  

Each of these HVAC components runs on high-voltage electricity, which can be dangerous to your safety and your HVAC system. Because of this, we never recommend homeowners replace, repair, or troubleshoot an air conditioner’s electrical components on their own.  

Instead, trust our licensed and experiences HVAC pros at Integrity Home Solutions to test, inspect, and restore your HVAC system. 

HVAC Maintenance You CAN Do 

To keep up with HVAC maintenance between seasonal tune-ups, here are a few things you can do!  

#1. Cleaning Around the Outdoor Unit 

Since it is outside, the condenser unit gets its fair share of wind, rain, and all the harsh weather that mother nature throws at it.  

Doing a monthly clean-up around the outside condenser unit will help plants and other biological matter from getting inside it and causing any problems.  

#2. Changing the Air Filter  

One of the easiest HVAC upkeep tasks that you can routinely do is changing your air filter every 30-60 days.  

This is such a quick task to do, yet many homeowners often forget to do it. Add a note to your calendar so you don’t forget!

#3. Clearing a Clogged Drain Line  

If your HVAC unit’s drain line is clogged, your system may stop running or blow warm air. If this happens, you might need to clean the system’s condensate drain line.  

To do so, follow these steps: 

  • Pour ¼ of vinegar into a measuring cup. 
  • Flip the breaker into the “off” position and make sure the air conditioner is turned off too.  
  • Look for the PVC pipe near the condenser unit outside your home. (Typically white, gray, or black.) 
  • Remove the cap of the drain line and look for any clogs.  
  • If a clog is visible, you can clear it manually with a vacuum or your hands. (Make sure to wear gloves!)  
  • Pour the vinegar into the condensate line and let it sit for 30 minutes or longer. 
  • Flush the line with water, and check to see if the clogs are gone and that everything is flowing freely.  
  • Repeat this process every three months to keep clogs at bay.
