10 Best HVAC Companies in Cornelius, NC

Signs You May Need HVAC Repair or Replacement

If your home's HVAC system isn't working correctly or nearing the end of its lifespan, you may need to hire an HVAC contractor for repairs or replacement. Watch for these common indicators that your system needs professional attention:

• Uneven heating/cooling or poor air circulation
• Corrosion, rust, or cracking
• Strange noises when the system turns on
• Frequent breakdowns and need for repairs
• Thermostat malfunctions or temperature control issues
• 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 technician can complete an inspection, identify problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Cornelius

HVAC installation or maintenance costs vary depending on your system. 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 utilize energy from either electric or gas sources.
• Heat pump: Heat pumps exchange warm and cold air between your home and outside. They don't generate their own heat or AC, so they function best in moderate climates and may not be as effective during Cornelius' hot summers.
• Packaged heating and air: Packaged HVAC systems work well in smaller homes. They consist of a single combined air conditioner and heating unit, typically located in an attic or basement. This unit is typically compact, energy-efficient, and easy to maintain.

The price of HVAC maintenance also depends on what kind of work you're having done. HVAC systems are complicated and may require different kinds of maintenance. The cost of some common repairs is as follows:

Ways to Save Money on HVAC Costs

Repairing or replacing your HVAC system when needed is crucial, but can be expensive. Luckily, there are steps you can take to reduce gradual wear and tear on your system.

• Change filters regularly. Air flows best through your HVAC system when you change out or clean the filters every 1–3 months. Also try not to let debris pile up on the external sections of your HVAC.
• Change the position of your blinds seasonally. Leaving your blinds open during the winter allows passive solar heating to warm your home. Closing the blinds in warmer seasons helps prevent some heat from getting inside. Doing both helps decrease the strain on your HVAC system.
• Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you identify and fix problems before they get too expensive.
• Keep your system clean. Keeping your indoor evaporator coil, ductwork, grills, and condenser fan blades clean helps your HVAC system function properly and lowers the risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when you notice things starting to get dirty.

How To Choose a Local HVAC Company

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

Compare Multiple Bids

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

Check Credentials

Look for an HVAC company that employs qualified technicians who have the necessary training and licenses. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory 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 North Carolina, HVAC contractors are required to be licensed by the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. A licensed firm may employ individuals who aren't all individually licensed; however, all work must be supervised by a licensed contractor. A contractor may hold multiple different licenses for different kinds of jobs. You should also read reviews and complaints on sites like the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with glowing reviews and testimonials about good customer experiences.

Understand Work Details

Make sure you know the details of any project before starting. If HVAC repairs are required, have your provider list which parts require replacement and why. Get confirmation that your technician will clean and test your system after the repair to verify that everything works. For replacement, ask your contractor to explain the new HVAC system estimated installation time, features, brand, model, and energy efficiency. Before work begins, 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

Trustworthy HVAC companies provide warranties for their work. Broader coverage is better, so make sure to compare warranties between companies. Choose the one that gives you the most coverage at a fair cost.

Get Quote in Writing

Always get HVAC quotes in writing before work begins. A detailed quote will cover costs for both materials and labor. Confirm that you understand all terms before signing the contract.
