Signs You May Need HVAC Repair or Replacement

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:

  • Frequent breakdowns and need for repairs
  • Unusually high energy bills
  • Poor air circulation or uneven heating/cooling
  • Thermostat malfunctions or temperature control issues
  • Refrigerant leaks
  • Odd noises when turning on
  • Cracking, corrosion, or rust
  • An HVAC system that's over 15 years old

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.

Cost of HVAC Installation and Maintenance in Dunwoody

Your HVAC installation or maintenance cost fluctuates depending on the style of unit. Common HVAC unit varieties include the following:

  • Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have internal units in each room to control temperature; these indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the benefit of being able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps transfer warm and cool air between your home and outside. They don't generate their own heating and cooling, so they work more efficiently in more temperate climates and may not be as effective during Dunwoody's hot summers.
  • Packaged heating and air: Packaged HVAC systems work best in smaller houses. They consist of a single combined heating and air conditioning unit, usually located in an attic or basement. This unit is typically space-saving, energy-efficient, and easy to maintain.

HVAC maintenance prices vary based on the specific services needed. HVAC systems can be complicated and potentially require several different services. Costs for typical jobs are as follows:

HVAC Unit TypeCost
Split$1,949-$4,969
Hybrid Split$3,950-$7,277
Heat Pump$3,058-$31,162
Packaged Heating and Air$256-$427

Ways to Save Money on HVAC Costs

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

  • Change the position of your blinds seasonally. Leaving your blinds open during the winter helps warm your home with passive solar heating. Closing the blinds in warmer seasons helps prevent the heat from getting inside. Doing both helps minimize the demand on your HVAC system.
  • Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you identify and fix problems before they get out of hand.
  • Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. We also recommend regularly clearing dirt and debris away from the outside areas of your system.
  • Keep your system clean. Cleaning your ductwork, indoor evaporator coil, grills, and condenser fan blades regularly helps keep your HVAC system working efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it begins to look dirty.
ServiceCost
Filter Replacement$64-$171
Condensor Cleaning$1,280-$3,839
Thermostat Repair$85-$213
Ductwork Cleaning$409-$1,024

How To Choose a Local HVAC Company

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.

Compare Multiple Bids

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.

Check Credentials

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.

Understand Work Details

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.

Compare Warranties

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.

Get Quote in Writing

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.

Frequently Asked Questions About HVAC in Dunwoody, GA

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:

  • Keep ductwork clean, and clean or change your air filters on a regular basis.
  • Schedule regular inspections to take care of problems as they come up.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you don't want to or can't buy one, try keeping your inside temperature as close to the outside temperature as you can.
  • When it comes time to replace any part of your HVAC system, explore Energy Star-certified or other environmentally friendly options.
