Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or old likely needs professional attention for repairs or replacement. Watch for these indicators that your system needs service:

  • Strange noises when the system turns on
  • Rust, cracking, or corrosion
  • Thermostat malfunctions or temperature control issues
  • Frequent breakdowns and need for repairs
  • Refrigerant leaks
  • Higher than normal energy bills
  • Uneven heating/cooling or poor air circulation
  • An HVAC system that's over 15 years old

Schedule an inspection if you notice any of these issues. A local technician can evaluate your system, detect problems, and determine whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Duluth

Your HVAC installation or maintenance cost fluctuates depending on the type of unit. 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 houses. They consist of a single combined heating and air conditioning unit, commonly 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:

HVAC Unit Type Cost
Split $1,913-$4,876
Hybrid Split $3,876-$7,140
Heat Pump $3,001-$30,579
Packaged Heating and Air $251-$419

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.

Service Cost
Filter Replacement $63-$167
Condensor Cleaning $1,256-$3,767
Thermostat Repair $84-$209
Ductwork Cleaning $402-$1,004

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

Reputable HVAC companies stand behind their work with warranties. Compare warranties from different companies, while remembering that broader coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

Get a written proposal before HVAC work begins. A comprehensive quote includes both labor and material costs. Make sure you understand and accept all terms before signing the contract.

Frequently Asked Questions About HVAC in Duluth, GA

Typically, you should have your HVAC system inspected twice a year. After an inspection, your technician will tell you what services are required. You should also call a technician if you start to notice any issues, such as leaks, strange noises, or unusual smells. If your home has ductwork, it should be serviced every few years.

The best times of the year to have an HVAC inspection are during the spring and fall. Technicians are often less busy during these times, making it easier to get an appointment. This also ensures that your system is ready for the summer and winter, the times of the year when it sees the most use.

You can save energy during the summer by reducing the amount of power your HVAC system uses to keep your home cool. Set your thermostat as close to the outside temperature as is comfortable, and try to avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any leaks around your windows and doors to help keep cool air in. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.

It takes between one and three days to have your HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this can take anywhere from a few hours up to two days. This timeline will be influenced by the size of your house, the accessibility of your system, and any new issues your technician runs into.

Usually, HVAC financing is through a third-party lender. If your HVAC company doesn't have financing options, you may consider taking out a loan on your own. Be sure to talk to your HVAC company and a financial advisor to find out what options are available to you and appropriate for your situation.

There are several ways you can make your HVAC system more energy-efficient:

  • Keep your air ducts clean and change or clean your air filters on a regular basis.
  • Have regular inspections to take care of issues as they come up.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you aren't able to purchase one, try keeping the temperature indoors as close to the outside temperature as is comfortable.
  • When it comes time to replace any part of your system, explore Energy Star-certified or other environmentally friendly options.
