Our technicians are fully trained and certified to provide service for all types and brands of heating and cooling equipment, and we are equipped to handle your HVAC needs for both residential and commercial properties.
When you contact us for help with your comfort systems, we take time to understand how you use your home or business, the age of your equipment, and any comfort or energy problems you have noticed. This allows us to recommend options that fit your space, your budget, and Atlanta-area climate demands, rather than a one-size-fits-all solution. Because we also provide electrical and plumbing services, we are able to spot related issues—such as thermostat wiring problems or drainage concerns—that might affect how well your system performs. Our goal is to give you clear information so you can decide what is right for your property without pressure.
Homes and businesses in Marietta face hot, humid summers and cool, damp winters, so keeping equipment properly sized and maintained can make a big difference in comfort and energy costs.

Whether you need a simple repair or a full system replacement, we aim to provide dependable HVAC service that supports comfort year-round.

Marietta Heating & AC Repair
We are committed to providing high-quality repair services for your heating and cooling equipment. When your system breaks down, we will respond to your call and provide prompt and reliable service to get your system back in shape. Our technicians have the training and experience to repair all brands and models of heating and air conditioning equipment.
When you schedule a repair visit, our team arrives in a fully stocked vehicle so most common issues can be addressed in a single trip. We listen carefully to the problems you have noticed—such as rooms that never feel comfortable, unusual cycling patterns, or odors from the vents—and then perform a thorough inspection. In many Marietta homes we visit, we find issues related to clogged filters, aging components, or improper previous installation that can often be corrected without replacing the entire system. We also look at factors like ductwork condition and thermostat operation to identify anything else that may be affecting performance.
Because heating and cooling failures often happen during extreme weather, we offer flexible scheduling and work hard to restore comfort as quickly as possible. Our technicians take time to walk you through what they found, review repair options, and explain any short-term versus long-term tradeoffs. If we see that frequent repairs are becoming more common, we may discuss whether it is time to consider working with a dedicated HVAC company for replacement planning so you are not surprised by an unexpected breakdown. Throughout the process, we aim to respect your time, your home, and your budget.
Common repair problems we can help you address include:
- Uneven temperatures that leave some rooms too hot while others stay too cold.
- Short cycling or constant running that makes the system turn on and off frequently or run nonstop.
- Unusual sounds or odors coming from the indoor or outdoor unit during operation.
- Poor airflow from vents that makes it difficult to keep up with Marietta’s summer heat or winter chill.
- Rising utility costs that suggest your equipment is working harder than it should to maintain comfort.
Call us for help when your system is:
- Not providing enough heating or cooling
- Not working
- Making strange noises
- Blowing warm air
- Causing your energy bills to rise
We start by diagnosing the problem and explaining the issue to you, so you can make an informed decision about the best way to proceed. Once we have your approval, we can get started on your repair. Our Marietta HVAC technicians are equipped with the latest diagnostic tools and technology to accurately locate the problem and provide dependable repair service.

Heating & Air Conditioning Installation in Marietta
If you are ready for a new heating or cooling system, Assured Comfort offers a great selection of quality equipment for your home or business. We are a factory-authorized dealer for Carrier, a leader in the industry for heating and cooling systems. Our technicians can help you find the right system for your home or commercial space and provide expert installation for your new equipment.
When we meet with you to plan a replacement, we look at more than just the size of your current unit. We ask about any comfort issues, hot or cold spots, and past repair history to determine what type of system will serve you best over time. Load calculations, ductwork evaluations, and consideration of Atlanta-area humidity all play a part in our recommendations. Because we install a wide range of Carrier options, we can review several choices with you and explain how each one may impact your energy usage, noise levels, and indoor comfort.
We install and replace:
- Furnaces
- Heat pumps
- Central air conditioning systems
- Ductless mini split systems
- Thermostats
- Indoor air quality equipment
One of the most important factors in the performance and longevity of your new heating or cooling system is the quality of the installation. Our technicians have received extensive training and have the skills and experience to provide dependable installation. We will make sure your new system is properly sized for your home or business to deliver efficient and reliable heating and cooling.
Maintenance for Your Heating & Cooling System in Marietta
Preventive maintenance is one of the most important things you can do for your heating and cooling system. Regular maintenance helps to prevent breakdowns, lower your energy bills, and extend the life of your equipment. We recommend maintenance for your heating system in the fall and your air conditioner in the spring.
During a maintenance visit, our technicians will clean your system, check all the components, and make any necessary adjustments. We will also look for any parts that show signs of wear and replace them before they fail. In addition, we can help you with air quality equipment, such as air cleaners and humidifiers, to improve the quality of the air in your home.
During a typical maintenance visit, you can expect us to:
- Inspect critical components such as coils, motors, and electrical connections for signs of stress or wear.
- Clean and adjust parts that affect airflow and efficiency, including filters and accessible drain lines.
- Check system performance by measuring temperatures and verifying that your equipment cycles on and off correctly.
- Review thermostat settings and make suggestions to help you balance comfort and energy use in your Marietta home.
- Answer questions about noises, comfort issues, or future upgrade options you may be considering.
Many of our customers in Marietta choose to schedule maintenance through a planned program so they do not have to remember seasonal tune-ups on their own. Regular visits are especially helpful in the Atlanta area, where long cooling seasons and frequent system cycling can put extra strain on equipment. By catching issues like low refrigerant, worn belts, or dirty coils early, we can often help you avoid inconvenient breakdowns during the hottest or coldest days of the year. Our team also notes developing concerns from one visit to the next so you can plan for future repairs or upgrades instead of facing sudden surprises from your HVAC company.
Frequently Asked Questions
How Often Should I Schedule HVAC Maintenance in Marietta?
Most homes benefit from maintenance twice a year—once for the air conditioner in the spring and once for the heating system in the fall. The long cooling season in the metro Atlanta area can cause systems to run for many hours a day, so regular tune-ups help keep components clean and catch wear before it leads to a breakdown. If you have pets, allergies, or older equipment, you may want to discuss more frequent filter changes or checkups with your service provider.
When Should I Consider Repair Versus Replacement?
Deciding between repairing and replacing often comes down to the age of the system, the cost of the repair, and how well the equipment keeps your home comfortable. If a unit in your Marietta home is more than 10–15 years old and needs frequent or expensive repairs, it may be time to start planning for a new system. A licensed contractor can walk you through options, including efficiency improvements and potential utility savings, so you can compare short-term costs with long-term comfort and reliability.
What Should I Ask Before Booking HVAC Service?
Before you schedule a visit, it helps to ask what the appointment will include, whether pricing is reviewed upfront, and how you will be updated if additional work is recommended. You may also want to confirm whether the company works on your specific brand and type of system and if they are familiar with local codes in Cobb County and the City of Marietta. Having these answers beforehand can make the visit smoother and give you more confidence in the recommendations you receive.
