10 Best HVAC Companies in Lexington, SC

Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Look for these indicators your system needs service:

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

If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, identify problems, and advise you whether you should repair or replace 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 isn’t suited for 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 functions in the same way as a normal split system, but has the benefit of being able to utilize energy from either electric or gas sources.
• Heat pump: Heat pumps circulate warm and cold air between your home and outside. They don't make their own heat or AC, so they function best in temperate climates and may not be as effective during Lexington's hot summers.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. These systems have a single heating and cooling unit, typically located in an attic or basement. They're compact, cost-effective, and easy to maintain.

HVAC maintenance costs differ based on the specific services needed. HVAC systems can be complex and potentially require a number of services. Fees for typical jobs are as follows:

Ways to Save Money on HVAC Costs

It’s important to take care of HVAC repairs and replacements when they are required, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.

• Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow smoothly through your system. Also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
• Keep your system clean. Keeping your indoor evaporator coil, ductwork, condenser fan blades, and grills clean helps your system function optimally and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
• Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help lower the work required from your home’s HVAC system.
• Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, lets you resolve them before they get out of hand.

How To Choose a Local HVAC Company

Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

Request estimates from three or more HVAC companies. Explain your issues and ask if technicians can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid companies that pressure you or demand payment before work.

Check Credentials

Choose an HVAC company with highly trained technicians who have appropriate licensing and experience. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual 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.

In South Carolina, HVAC contractors are required to be licensed as mechanical contractors by the South Carolina Department of Labor, Licensing and Regulation Contractor's Licensing Board. Contractors can have multiple specialities, such as Heating, Electrical, Refrigeration, Air Conditioning, or Plumbing, depending on what's required for a specific project. Contractors need to have one year of work experience and pass an exam to be licensed. Your city or county may have additional requirements. You should also look at reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a company with positive reviews and reports of good customer experiences.

Understand Work Details

It’s important to understand what the work process is going to look like. For HVAC repairs, the company should list the specific parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC, request that the company explain the new estimated installation time, features, brand, energy efficiency, and model. Before signing a contract, be sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.

Compare Warranties

Reliable HVAC companies offer warranties on service and installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the most comprehensive protection for the fairest price.

Get Quote in Writing

Always get HVAC quotes in writing before work begins. A thorough quote covers costs for both materials and labor. Ensure that you understand all terms before signing the contract.
