Northern Atlanta and Marietta Air Conditioning Contractor

The Air Conditioning Services We Offer

As a full-service air conditioning company, we are your one-stop shop for all residential and commercial AC services. Our experts work on new AC installations and handle varied needs afterward, including:

  • Air Conditioning Replacement. We recommend AC replacement if your system is over 12 years old, has obsolete or broken parts, and experiences frequent breakdowns/expensive repairs despite yearly tune-ups. Our experts will handle the delicate replacement air conditioning installation to ensure peak performance. We'll balance the ductwork properly, retrofit the new system, and even install a suitable smart thermostat.
  • AC Repair. HVAC components are bound to wear after a while, causing the system to break down. When that happens, you can count on the Cool Air Mechanical team for prompt air conditioning repair services in Marietta or the surrounding metro Atlanta area. Our technicians will assess the situation and repair or replace the faulty parts on the same day we visit.
  • Air Conditioning Maintenance. Air conditioners typically lose about 5% of their total efficiency yearly without proper maintenance. That's why you should consider scheduling regular AC service/tune-ups for better cooling and performance. Our crew will also inspect the equipment and repair any underlying issues during an AC maintenance appointment to prevent frequent malfunctions during the summer when you need your system the most.

Air Conditioning FAQs — And Answers to Your Burning Questions

Having more than a decade of experience in the AC industry, our team has had various inquiries on AC issues. We have crafted the FAQ section below to answer some frequently asked air conditioning questions.

Do Bigger Air Conditioning Units Perform Better?

Bigger isn't always better when it comes to air conditioners. The rule of thumb for optimal air conditioning performance is to get a system well-sized for your home's cooling needs. While an oversized AC can cool your space quicker, it may bring lots of problems, including:

  • Uneven cooling. An oversized AC will experience frequent short cycles — starting up and stopping on repeat. That means the rooms nearest the system will get cold, while rooms farther from the system won't get enough cooling before the system shuts down again.
  • Inefficient dehumidification. Air conditioners also eliminate moisture from the indoor air, which requires a long running time. A system that's too big for your residence or business will cool air fast and shut down quickly before proper dehumidification.
  • Frequent breakdowns. As the oversized AC keeps cycling on and off, its components will experience more wear and tear. That translates to the need for regular AC repair services.
  • More energy use. You'll incur higher electricity bills with an oversized AC than with an appropriately sized one. Worse, the system will never reach peak efficiency since it quickly lowers the temperature to the thermostat setting and shuts down, or short-cycles, before reaching an efficient level.

How Long Does HVAC Equipment Last?

Well-maintained HVACs can last anywhere between 10 and 25 years. However, the type of system you have plays a huge role in its life span — for instance, window systems usually last 10 years, while heat pumps may run for up to 25 years. It's also worth noting that HVACs in homes with older/insufficient attic insulation and unsealed air leaks will overwork and automatically have a shorter life expectancy.

If I Have an Older System, Can I Save Money by Just Replacing the Outdoor Unit?

Not necessarily. Partially replacing the old AC's components might lead to costly problems. To understand this, it's worth mentioning that the evaporator coil in the indoor unit and the compressor and condenser coils in the outdoor units must work in unison for efficient HVAC functions. Any mismatch in the technology applied in the AC components will bring about incompatibility and possibly component failure. 

Therefore, when you replace the outdoor unit and couple its new components with the old indoor parts, a mismatch will occur due to the difference in operational efficiency — older coils will have decreased efficiency, and vice versa. This stress can cause motor or compressor failure, which only means spending more on replacement parts. 

We recommend replacing indoor and outdoor units during system upgrades. 

Why Is My AC System Leaking Water?

AC water leaks can occur for a few reasons:

  • A clogged condensate drain line. When blocked with dust, dirt, or mold, this drain will block moisture flow to the outside and cause backflow.
  • Dirty air filter. It'll block airflow to the evaporator coil, which will become too cold, freeze, and leak as it overflows from the pan when it begins to melt.
  • Low refrigerant. A low refrigerant level causes lower pressure in the AC system, which can freeze the evaporator coil and create a watery mess.
  • Damaged or rusted drain pans. Decades-old systems with rusty drain pans usually exhibit leak problems.

How Often Should AC Coils Be Cleaned?

At least once a year cleaning helps eliminate accumulated dust or dirt from the AC coils. This debris insulates the coils from the surrounding air and causes inefficient heat transfer between the inside and outside. If left uncleaned, the AC won't perform well.

What Is the Best Time to Buy an Air Conditioner?

Fall and spring are the best times to buy new ACs. The secret to great deals is to time your purchase opposite the market trend. In this case, that's the time between summer and winter, as the weather is moderate, and the demands on the HVAC industry aren’t as heavy.
