Today's Homeowner looks at dozens of datapoints on hvac companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
If your home's HVAC system isn't working correctly or getting old, you might need an HVAC contractor for maintenance or replacement. Look for these common signs that your system requires expert attention:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can pinpoint problems and let you know whether repair or full HVAC replacement is needed.
HVAC installation or maintenance costs vary depending on your system. Common HVAC unit varieties include the following:
HVAC maintenance costs vary depending on the particular service needed. HVAC systems are complicated and might require different kinds of maintenance. Prices for common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,734-$4,421 | |
| Hybrid Split | $3,514-$6,474 | |
| Heat Pump | $2,721-$27,725 | |
| Packaged Heating and Air | $228-$379 |
Fixing your HVAC by repairing or replacing parts when needed is crucial, but can be expensive. Thankfully, there are actions you can take to minimize wear and tear over time on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $57-$152 | |
| Condensor Cleaning | $1,138-$3,415 | |
| Thermostat Repair | $76-$190 | |
| Ductwork Cleaning | $364-$911 |
Knowing what makes a trustworthy HVAC company is crucial for a smooth installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Contact at least three HVAC contractors for quotes. Explain your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand upfront payment.
Look for an HVAC company that employs skilled 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 required 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.
In South Carolina, HVAC contractors must be licensed as mechanical contractors through the South Carolina Department of Labor, Licensing and Regulation Contractor's Licensing Board. This license can have multiple specialities, such as Heating, Air Conditioning, Plumbing, Electrical, or Refrigeration, depending on what's needed for a specific project. Contractors need to have one year of work experience and pass an exam to earn a license. Individual cities or counties may have additional requirements. You should also read reviews and complaints on sites like Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with glowing reviews and reports of good customer experiences.
Make sure you understand the details of any project before starting. For HVAC repairs, have your provider detail which parts need replacement and why. Get confirmation that your technician will clean and test the entire system after the repair to verify that everything works. When replacing your HVAC system, request that the installation company describe the new model, brand, features, energy efficiency, and estimated installation time. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.
Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that provides the most comprehensive protection for a fair price.
Always get quotes for HVAC service in writing before committing to a provider. An itemized quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.
Generally, your HVAC system should be inspected twice a year. After that inspection, your HVAC technician will tell you what, if any, services are needed. You should also have an inspection if you start to notice any issues, such as strange noises, leaks, or unusual smells. If your home has ductwork, it should be serviced every few years.
The best times to have your HVAC system inspected are during the spring and fall. Technicians are less busy during these times, so it will be easier to get an appointment. This also helps get your system ready for the summer and winter, which is when it normally sees the most use.
You can save energy during the summer by making it easier for your HVAC system 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 well-maintained and seal any leaks around your windows and doors to avoid letting cool air escape. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.
Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing a furnace or air conditioning unit takes anywhere from about half a day up to two days. The exact amount of time will vary depending on factors like the size of your home, how easily accessible different areas are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you'll want a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Gaffney, you may be able to make do with a lower-capacity furnace.
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 Gaffney, you'll likely want a unit on the higher end of this range. Typically, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Usually, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer these options, you might consider taking out your own loan. Be sure to speak with a financial advisor and your HVAC company to determine what options are available to you and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
