"No findings, no solution, no explanation… collected the fee… the issue is still there. I had Triad Mechanical Company for our HVAC issue that the outdoor unit is not running. I told Paul, the assigned technician, that we had tried resetting the power to the outdoor unit but that only brought the unit back on running for a few days before it stopped running again. I asked Paul’s help diagnose the issue for the root cause. However, when I came to the property just a few minutes later than Paul, he told me that he had done his work already, well, by simply resetting the power to the unit! (although I told him that we already tried that but it didn’t work!)… He didn’t have the patience to explain to me what diagnosis he had done (within that a few minutes) and he didn’t even bother to come off his truck to show me but saying “go ask your tenant”. He collected the fee and left. I will never trust nor use Triad Mechanical Company again!"

FAQs for heating and air conditioning service projects in Snellville, GA

Knowing how long your existing HVAC units can last is essential to determine if you need a repair or replacement. Typically, most modern air conditioning units can last between 15 to 20 years, and most furnaces can work properly for 15 to 30 years. If your HVAC system is on the older side and you decide to replace one unit, it might make sense to replace both simultaneously to save on costs and future hassle.

While different HVAC contractors might offer higher or lower prices than competitors, the best time to replace your HVAC system is when customer demand is low. The beginning of summer and the beginning of winter bring the most demand for HVAC systems, so if you can, consider replacing your HVAC units in the early spring or fall. Many HVAC companies offer special off-season coupons that help lower the overall cost.  

The average cost to hire an HVAC contractor is between $50 and $150 per hour if charging hourly. However, some HVAC contractors will charge a flat fee by the type of service they are performing—for example, an inspection can cost between $150 to $500. Keep in mind that emergency repairs—which are made after business hours or around major holidays—generally cost more than scheduled repairs.

Yes, most states require HVAC technicians to be certified, and for good reason. Hiring an unlicensed HVAC technician could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The average cost of HVAC repairs is around $350. However, that price can be as low as $100 or as high as $2,000 or more, depending on the repair. For example, replacing a capacitor is a relatively inexpensive repair, ranging from $100 to $500. However, a compressor repair is a more expensive repair, ranging from $750 to $2,000.
