Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs professional attention from a technician who can make repairs or install a new unit. Watch out for these common signs that your HVAC needs service:

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

If you notice any of these HVAC issues, have a technician inspect your system. A local professional can identify problems and determine whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Jefferson

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 air or heating, you probably have a split or mini-split system instead. Split HVAC systems have interior 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 providing the option to draw on either electricity or gas for energy.
  • Heat pump: Heat pumps transfer warm and cool air between your home and the outside. These systems don't make their own heat or AC, so they work more efficiently in more temperate climates and may not be as effective during Jefferson's hot summers.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller homes. These systems have a single combined AC and heating, normally located in an attic or basement. They're compact, cost-effective, and easy to maintain.

The cost of HVAC maintenance also varies depending on the kind of work you're having done. HVAC systems are complex and might require different kinds of maintenance. The prices of some common jobs are as follows:

HVAC Unit TypeCost
Split$1,879-$4,790
Hybrid Split$3,807-$7,014
Heat Pump$2,948-$30,038
Packaged Heating and Air$247-$411

Ways to Save Money on HVAC Costs

Fixing your HVAC by repairing or replacing parts when needed is crucial, but can be costly. Fortunately, there are actions you can take to minimize wear and tear over time on your system.

  • Keep your system clean. Regularly cleaning indoor evaporator coil, condenser fan blades, ductwork, and grills helps keep your HVAC system running efficiently and lowers the risk of mold. The National Air Duct Cleaners Association advises cleaning your system when it starts to look dirty.
  • 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 decreases the amount of work your HVAC system is required to do.
  • Change filters regularly. Air flows through your HVAC system most effectively when you change out or clean the filters every 1–3 months. Also avoid letting debris pile up on the outside areas of your HVAC.
  • Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills regularly — helps you get ahead of problems before they get too expensive.
ServiceCost
Filter Replacement$62-$164
Condensor Cleaning$1,233-$3,700
Thermostat Repair$82-$206
Ductwork Cleaning$395-$987

How To Choose a Local HVAC Company

Finding the right HVAC company is vital for an easy 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

Contact at least three HVAC providers for quotes. Explain the issues and have specialists visit to inspect your HVAC system if possible. Compare the companies' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.

Check Credentials

When hiring an HVAC provider, choose one with technicians that have the appropriate training, licenses, and experience. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." An individual must pass an exam (the type of exam depends on what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.

In Georgia, all HVAC contractors are required to be licensed. They may hold a Class I or Class II license. A Class I license requires four years of experience and limits 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 look at reviews and complaints on sites like the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with glowing reviews and reports of fantastic customer experiences.

Understand Work Details

Always make sure you understand what a company’s process looks like. When HVAC repairs are needed, ask your provider to specify which parts require replacement and why. Confirm that your technician will clean and test your system after finishing the work to guarantee proper operation. When getting a replacement, ask the contractor to explain the new HVAC system energy efficiency, estimated installation time, brand, features, and model. 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

Good HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that provides the most comprehensive protection for the fairest price.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A comprehensive quote will cover costs for both labor and materials. Make sure that you agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Jefferson, GA

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

The best times to have your HVAC system inspected are the spring and fall. Technicians are 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, when it typically gets 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. Keep your thermostat temperature 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 avoid letting cool air escape. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.

Generally, HVAC installation or replacement takes one to three days for the entire system. Installing or replacing an air conditioning unit or a furnace takes anywhere from about half a day up to two days. The exact amount of time will be based on things like how large your home is, how easily accessible different areas are, and whether your technician finds any problems.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Jefferson, you'll probably want to choose a unit that's on the higher end of this range. If your home is larger than 1,000 square feet, central air will be more effective than window units for cooling.

For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Jefferson, you might be able to make do with a lower-capacity furnace.

Your HVAC company may have financing options through a third-party lender, or you might be able to obtain a loan on your own. It's a good idea to discuss payment options with your HVAC company and a financial advisor to make sure that you're choosing the best option for you.

There are a number of ways you can make your HVAC system more energy-efficient:

  • Keep your air ducts clean and clean or change your air filters on a regular basis.
  • Schedule regular inspections to take care of issues as they arise.
  • 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 you can.
  • When it comes time to replace any part of your HVAC system, see if there are Energy Star-certified or similar environmentally friendly options.
