These HVAC red flags indicate that you should have your system evaluated. A local technician can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.
The price of HVAC installation or maintenance will vary depending on the type of unit you have. Common types of HVAC units include the following:

Knowing the right things to look for in an HVAC company is key for a smooth repair or installation. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.
Request estimates from at least three HVAC contractors. Describe your issues and ask if technicians can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid contractors that pressure you or demand payment before work.
Look for an HVAC company that employs skilled technicians with 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 contractors 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 the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.
HVAC contractors in South Carolina must be licensed as mechanical contractors via the South Carolina Department of Labor, Licensing and Regulation Contractor's Licensing Board. This license can have multiple specialities, such as Electrical, Heating, Air Conditioning, Plumbing, or Refrigeration, depending on what's needed for a specific project. Contractors must have one year of work experience and pass an exam to obtain a license. Your city or county may have additional requirements. Also check a company's reviews and complaints on sites such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with great feedback and stories of satisfied customers.
Make sure you understand the details of your project before it begins. If HVAC repairs are required, have your provider specify which parts need replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. When replacing your HVAC system, ask the contractor to describe the new estimated installation time, brand, energy efficiency, features, and model. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.
Trustworthy HVAC companies provide warranties for their services. The broader the coverage, the better, so make sure to compare warranties between companies. Choose the one that provides the most comprehensive coverage at a fair cost.
Always get HVAC estimates in writing before work begins. A detailed quote will cover costs for both labor and materials. Confirm that you understand all terms before signing the contract.
You should have your HVAC system inspected about twice annually. After completing their inspection, your technician will inform you what services are needed. You should also schedule an inspection 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.
Usually, it's smart to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. 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 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.
It takes around one to three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this might take between half a day and two days. This timeline will be influenced by the size of your house, how easily accessible your system is, and any issues your technician discovers.
For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Charleston, you may be able to make do with a furnace on the lower end of this range.
For a 2,000-square-foot home, you'll also want an air conditioning unit with between 2.5 and 5 tons of capacity. In Charleston, you'll likely need a unit on the higher end of this range. Generally, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
Typically, HVAC financing is offered through a third-party lender. If your HVAC company doesn't have financing options, you might 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 and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
