How to Choose the Best HVAC Company in South Fulton, GA

Whether you’re looking for HVAC repair or installation, knowing how to choose the best HVAC company in South Fulton, GA, is essential. Your home’s comfort relies on a consistently working HVAC system. Here’s what to consider when looking for the best HVAC companies near you.

  • Proper license and insurance: To operate an HVAC company in Georgia, business owners must have proper licensure from the Georgia State Board of Conditioned Air Contractors and proper liability insurance. Be sure to ask the HVAC professional for copies of their licenses and insurance before working with them; don’t just take their word for it. 
  • Ensure adequate experience: Ask your HVAC pro about their experience in addressing your HVAC issues or installing the type and brand of air conditioning or furnace you want to purchase.
  • Get a free estimate: Reputable HVAC companies in South Fulton will provide a free estimate for your HVAC repairs or installation. Ask for an estimate in writing to see what’s included and to help you compare offers.
  • Obtain quotes from multiple companies: Compare quotes from several service providers to determine who provides the best prices while ensuring top-notch service.
  • Read reviews: Check out reviews left by past customers to determine a company’s reputation. Don’t be afraid to ask them for testimonials or referrals to talk to previous clients yourself.

HVAC Services Offered by Companies in South Fulton, GA

At My Home Pros, we partner with HVAC companies that offer various HVAC services to ensure temperature control and comfort in your South Fulton home. The services you’ll find include:

  • AC and Furnace Repair: Air conditioners and furnaces naturally break down after constant use. Having the best HVAC pros available to fix the repair is essential. You should partner with a company that offers quality services and around-the-clock service for any emergencies you experience with your HVAC system.
  • AC and Furnace Install or Replacement: Air conditioning units and furnaces last 15 – 25 years, depending on the brand, type, and how well they are maintained. This means if you have lived in your home for at least 10 years or bought a home with an A/C or furnace with many years on it already, you may need a replacement.
  • AC and Furnace Maintenance: Proper upkeep of your AC and furnace units prevents unnecessary breakdowns and may lengthen your appliance’s longevity. Many companies offer affordable maintenance plans to ensure you stay on track with your AC and furnace maintenance.

Common HVAC Issues Requiring Repair

While there are many reasons why your HVAC unit may need repairs, there are typically common signs such as your system blowing warm air, hearing loud sounds or rattling, and smelling odd odors that suggest it’s time to call for help. To help you get a head start, here is a list of some of the most common AC issues that require repairs:

Refrigerant leak detection

Detecting a refrigerant leak is an important AC repair before recharging. If a technician recharges the refrigerant without checking for leaks, it will only temporarily solve the problem until the new refrigerant leaks, leaving you in the same position. Fixing the leak first and then recharging is the best course of action.  

Compressor repair or replacement

Determining whether to repair or replace a broken compressor depends on the age of your unit and the number of issues you’ve had with it. Repair may make the most sense if it’s relatively new, but replacement may buy you more time if you’ve had it for a while or it’s broken down before.  

Fan motor replacement

Condenser fan motors are the most common AC parts that fail but are typically the least expensive to replace. The fan motor powers the fan, which produces cold air throughout your house. The parts and labor are relatively inexpensive, making this an easy AC repair.  

Thermostat repair or calibration

If you notice fluctuations in the airflow throughout your house or your AC runs more often than usual, a thermostat repair or calibration may be necessary. If you aren’t familiar with how to do this, the thermostat is damaged, or there are issues with the wiring, it’s best to look for professional AC repair companies near you.  

Ductwork inspection and repair

Ductwork leaks can cause you to lose as much as 20% – 30% of your cool air, forcing your AC unit to work harder. A ductwork inspection can determine if there are leaks or if they require cleaning to provide proper airflow.

HVAC Repair and Installation Costs in South Fulton, GA

When it comes time to decide which HVAC company to choose for you AC, Furnace, or Heat Pump repair or installation, knowing the average costs in South Fulton is of utmost importance to ensure you are getting a fair deal. 

While costs can vary significantly based on a few factors, the average cost to repair an HVAC unit near South Fulton is $461, and can range from $97 to $826. On the other hand, the average cost to replace or install an HVAC unit near South Fulton is $8,294, and can range from $2,868 to $19,842.

Use these estimates as a guide when you’re reviewing quotes from local HVAC companies, and as mentioned previously, be sure to compare quotes from multiple HVAC companies in South Fulton to ensure you are getting the best deal. 

Deciding Between HVAC Repair vs HVAC Replacement

The HVAC industry uses a simple rule of thumb to determine whether to repair or replace a faulty HVAC unit. All you need is the cost of repairs and the HVAC unit’s age.

Multiply the unit’s age by the cost, and if the answer exceeds $5,000, you should replace instead of repair your AC.

For example, your AC unit is six years old, and the repair will cost $2,000; your answer is $12,000, which exceeds $5,000, so replacement is best.

Other signs to look for when considering replacement versus repair include:

  • Frequent breakdowns
  • Energy inefficiency
  • Higher than normal electric bills
  • Uneven or poor airflow

When deciding if you should consider HVAC installation, also look into any attractive financing offers the manufacturer or installer offers, as it may make more financial sense to take advantage and get a new system.


Finding a trusted HVAC company in South Fulton, GA, is essential for controlling the temperature in your home year-round. Whether you’re looking for HVAC installation, repair, or maintenance, having a reputable company to keep your home comfortable is essential.
