If your HVAC system is having issues or getting old, it likely needs repairs or replacement from an HVAC company. Look for these indicators your system needs service:
If you notice any of these HVAC issues, we recommend having a technician inspect your system. A local professional can identify problems and let you know whether whether repairing or getting a new HVAC unit is the correct solution.

Knowing what makes a trustworthy HVAC company is vital for a smooth installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.
Request estimates from at least three HVAC providers. Explain your issues and ask if specialists can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid companies that pressure you or demand payment before work.
It's important to choose an HVAC company that employs technicians with the appropriate 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, individuals must pass an exam (the specific exam depends on the 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 by the state.
All HVAC contractors in Georgia must be licensed. They may hold 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. Class II licenses require five years of experience and are 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. Pick a company with positive reviews and reports of good customer experiences.
Make sure you understand the details of any project before it begins. If HVAC repairs are required, have your provider specify which parts require replacement and why. Confirm that your technician will clean and test the system after the repair to verify that everything works. When replacing your HVAC, ask your installation company to provide details on the new features, model, brand, estimated installation time, and energy efficiency. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.
Trustworthy HVAC companies back their work with warranties. Look at warranties from different companies, keeping in mind that broader coverage is better. Look for the provider that offers the most coverage for a fair price.
Always get HVAC quotes in writing before work begins. A comprehensive quote covers costs for both labor and materials. Make sure that you understand all terms before signing the contract.
Generally, you should have your HVAC system inspected twice a year. After an inspection, your HVAC technician will tell you what services are needed. You should also have your system inspected and serviced if you notice any new issues, like unusual smells, strange noises, or leaks. If your home has ductwork, it should be serviced every few years.
The best times of the year to have your HVAC system inspected are during the spring and fall. Technicians are less busy during these times, making it easier to get an appointment. This also helps get your system ready for the summer and winter, when it typically gets the most use.
You can save energy during the summer by making it easier for your HVAC system to keep your home cool. Keep your thermostat temperature as close to the outside temperature as you comfortably can, and try to avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any leaks around your windows and doors to avoid letting cool air escape. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.
Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing an air conditioning unit or a furnace can take as little as half a day or as much as two days. The exact amount of time will depend on factors like the size of your house, how easily accessible different sections are, and whether your technician discovers any problems.
For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Dunwoody, you may be able to make do with a lower-capacity furnace.
For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with around 2.5 to 5 tons of capacity. In Dunwoody, you'll likely look for a unit on the higher end of this range. In general, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
Usually, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer these options, you could consider taking out a loan on your own. Be sure to talk to your HVAC company and a financial advisor to learn what options are available to you and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
