Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or nearing the end of its lifespan, you might need an HVAC contractor for maintenance or replacement. Watch for these common indicators that your system requires professional attention:

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

These HVAC red flags indicate that you should have your system evaluated. A local provider can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Lexington

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 likely have a split or mini-split system. Split systems have interior units in each room to regulate temperature; these indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to draw power from either electric or gas sources.
  • Heat pump: Heat pumps work by circulating warm and cool air between your home and the outdoors. These systems don't produce heat or air conditioning themselves, and are better for more moderate climates. They may not be as effective during Lexington's hot summers.
  • Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined air conditioner and heating unit, commonly located in a basement or attic. This unit is typically space-saving, energy-efficient, and easy to maintain.

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

HVAC Unit Type Cost
Split $1,823-$4,646
Hybrid Split $3,693-$6,804
Heat Pump $2,860-$29,138
Packaged Heating and Air $239-$399

Ways to Save Money on HVAC Costs

Essential HVAC maintenance is important, but can be expensive. Luckily, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.

  • Change filters regularly. Replacing your air filters or washing them every 30–90 days allows smooth air circulation through your HVAC system. Also try to keep debris from accumulating on the external parts of your HVAC.
  • Keep your system clean. Keeping your grills, condenser fan blades, 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 whenever it begins 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.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, helps you resolve them before they get too expensive.

Service Cost
Filter Replacement $60-$160
Condensor Cleaning $1,196-$3,589
Thermostat Repair $80-$199
Ductwork Cleaning $383-$957

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Look for an experienced, licensed contractor that can offer you peace of mind and make sure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

Get quotes from three or more HVAC companies. Describe your issues and ask if specialists can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.

Check Credentials

Look for an HVAC company that employs qualified technicians with the necessary training and licenses. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for any individual who helps "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 on a state-by-state basis.

HVAC contractors in South Carolina are required to be licensed as mechanical contractors by the South Carolina Department of Labor, Licensing and Regulation Contractor's Licensing Board. This license can have multiple specialities, such as Air Conditioning, Refrigeration, Electrical, Plumbing, or Heating, depending on what's required for a specific project. Contractors need to have one year of work experience and must pass an exam to earn a license. Your city or county may have additional requirements. You should also check a provider's reviews and complaints with organizations such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Look for a a provider with positive reviews and a history of good customer service.

Understand Work Details

Always make sure you know the details of a planned project. For HVAC repairs, your provider should list which parts need replacement and why. Confirm that your technician will clean and test the full system after repairs are completed to verify that it’s working properly. When replacing your HVAC, ask the installation company to provide details on the new model, features, estimated installation time, energy efficiency, and brand. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

Trustworthy HVAC companies provide warranties for their services. The broader the coverage, the better, so make sure to review warranties between providers. Choose the one that provides the most comprehensive coverage at a fair cost.

Get Quote in Writing

Always get quotes for HVAC service in writing before committing to a provider. A comprehensive quote should cover both materials and labor. Make sure you review all terms before signing a contract.

Frequently Asked Questions About HVAC in Lexington, SC

You should have your HVAC system inspected approximately twice annually. Following an inspection, your technician will inform you what services are needed. You should also have your system inspected if you notice new issues such as unusual smells, strange noises, or leaks. If your home has ductwork, you should have it inspected every few years.

Normally, it's smart to have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared for the summer and winter, when it probably sees the most use.

You can save energy during the summer by making it easier for your HVAC system to keep your home cool. Set your thermostat 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 doors and windows 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 a furnace or a single air conditioning unit, this may take between half a day and two days. This timeline can be affected by the size of your home, the accessibility of your system, and any issues your technician discovers.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Lexington, you'll probably want to explore units on the higher end of this range. For a house over 1,000 square feet, central air will usually be more effective than window units for cooling.

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

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 regularly.
  • Have regular inspections to take care of problems 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 to keep your inside temperature as close to the outside temperature as you can.
  • When replacing part of your HVAC system, explore Energy Star-certified or other environmentally friendly options.
