10 Best HVAC Companies in Duluth, GA

Signs You May Need HVAC Repair or Replacement

If your HVAC system is having issues or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Watch for these indicators your system needs service:

• Odd noises when the system turns on
• Rust, cracking, or corrosion
• Temperature control issues or thermostat malfunctions
• Frequent breakdowns and need for repairs
• Refrigerant leaks
• Unusually high energy bills
• Uneven heating/cooling or poor air circulation
• An HVAC system that's over 15 years old

If you notice any of these HVAC issues, you should have a technician inspect your system. A local professional can diagnose problems and let you know whether whether fixing or replacing your HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Duluth

HVAC installation or maintenance prices change depending on your system. Common HVAC unit varieties include the following:

• Split or mini-split: If your home doesn’t have the ductwork for central heating and cooling, you probably have a split or mini-split system instead. Split HVAC systems have internal units in each room to regulate temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions comparably to a regular split system. It gives flexibility by having the option to use either electricity or gas for energy.
• Heat pump: Heat pumps exchange warm and cold air between your home and the outdoors. They don't produce their own heat or AC, so they function best in moderate climates and may not be as effective during Duluth's hot summers.
• Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined air conditioner and heating unit, typically located in a basement or attic. This unit is typically small, energy-efficient, and straightforward to maintain.

HVAC maintenance prices differ based on the specific services required. HVAC systems can be complex and potentially require a number of services. Costs for typical jobs are as follows:

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be expensive. Thankfully, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.

• Change the position of your blinds seasonally. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both helps minimize the amount of work your HVAC system must perform.
• Keep your system clean. Keeping your condenser fan blades, grills, ductwork, and indoor evaporator coil clean helps your system function optimally and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system when it starts to look dirty.
• Change filters regularly. Switching out or cleaning your air filters every 1–3 months helps air flow smoothly through your HVAC system. We also recommend regularly clearing dirt and debris away from the external parts of your system.
• Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills routinely — helps you get ahead of problems before they get too expensive.

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can fix your system, providing you with effective heating and cooling for your home.

Compare Multiple Bids

Get quotes from at least three HVAC companies. Describe your issues and ask if technicians can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the specific exam depends on what kind of equipment they intend to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled on a state-by-state basis.

In Georgia, all HVAC contractors are required to be licensed. They can have either a Class I or Class II license. Class I licenses require four years of experience and limit the type of equipment a contractor can work on. A Class II license requires five years of experience and is unrestricted. You can verify a license on the Secretary of State's website. You should also read reviews and complaints on sites like the Better Business Bureau (BBB), Yelp, and Google Reviews. Choose a company with glowing reviews and testimonials about good customer experiences.

Understand Work Details

Always make sure you understand the details of your project. When HVAC repairs are required, your provider should list which parts require replacement and why. Confirm that your technician will clean and test the full system after repairs are done to ensure that it’s working properly. When getting a replacement, ask the contractor to explain the new HVAC system brand, features, energy efficiency, model, and estimated installation time. Before signing a contract, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.

Compare Warranties

Trustworthy HVAC companies provide warranties for their services. Broader coverage is better, so make sure to review warranties between providers. Choose the one that offers the best coverage at a fair cost.

Get Quote in Writing

Get written estimates before beginning HVAC work. The quote should include costs for both materials and labor. Read all terms carefully before signing.
