Choosing the Right Service for HVAC Control Board Troubleshooting

Have you noticed poor temperature regulation from your HVAC system? Does your furnace refuse to turn on? You might require HVAC control board troubleshooting. As Canton’s trusted HVAC company, Green Energy Mechanical Inc. can help you learn more about HVAC control boards and how to choose the right expert for your needs.

What Is the HVAC Control Board?

Your HVAC system’s control board controls everything from temperature to the fans and more. You can find it where the thermostat wires connect to the heating and cooling system, usually on the furnace. Like most pieces of technology, the control board can malfunction when it gets too old or suffers damage.

Signs Your Control Board Needs Help

How can you know you need help with your HVAC control board? Consider these signs:

  • Warning lights: Your control board has warning lights that illuminate when something’s wrong. The lights will blink in certain patterns to communicate the issue. An HVAC technician can interpret these blinking lights to diagnose and fix the issue.
  • Stuck switches: Too much or too little voltage can make the switches on the control board stick. This can lead to overheating, which causes further damage.
  • Bad connections: Over time, the solder that secures the connection in your control board can crack or come loose. If your HVAC system doesn’t turn on or has other power issues, a bad connection is the likely cause.
  • Poor temperature regulation: Any number of issues can prevent your HVAC system from effectively regulating the temperature in your home. However, a faulty control board is one of the most common reasons. An HVAC repair specialist can fix the problem.

How To Choose the Right Control Board Service

If you need HVAC control board troubleshooting, you’ll want the most reliable service to avoid further problems. To find the best option, consider these five criteria.

1. Consider Reviews and Referrals

Reviews and referrals are one of the best ways to choose a good HVAC service company because they’re not affected by the company’s bias. You probably know someone who’s needed HVAC help in the past, and you can ask them about their experience and who they recommend for the job.

You can also look at reviews from customers on Google or other third-party review sites. While not every review presents an unbiased account of the customer’s experience, if you notice positive or negative trends across several, you can assume it says something genuine about the company.

2. Inspect Their Service Information

Whether you’re facing the extreme heat of summer or the cold of winter, sometimes a broken control board requires emergency repairs to keep you safe. When you choose an HVAC company, make sure they’re available for emergency help and that they provide service in your area.

It’s best to choose a local company or one that maintains a branch near you. While a more distant provider might offer to drive to your location, you’ll end up paying much more and waiting longer for them to arrive than when choosing a qualified local technician.

3. Verify Their Certifications

The most reliable HVAC companies maintain several certifications that help their customers know they’re qualified for the job. The most common certifications you should look for include:

  • ASHRAE certification: The American Society of Heating, Refrigeration, and Air Conditioning Engineers dedicates its organization to certifying technicians in the most modern HVAC technology.
  • AHRI certification: The Institute of Air Conditioning, Heating, and Refrigeration provides one of the most commonly sought-after certifications.
  • ASME certification: While the American Society of Engineers provides a certification that covers more than just the HVAC system, many engineers with ASME certification could repair your HVAC system.

4. Confirm Their Experience

Examine the company’s website to ensure they have the experience required to deliver quality repairs. Ask the following questions:

  • How many years have they been in business?
  • Do they have experience with high-efficiency HVAC systems?
  • Are they a local chain with specific knowledge of how the climate affects your HVAC system?

5. Obtain an Estimate

As the final step, obtain an estimate from two or three HVAC companies of your choice. Don’t necessarily take the lowest offer, and use the estimate in the context of the other considerations to choose the best option.
