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 HVAC system is broken or getting old, it likely needs repairs or replacement from an HVAC company. Look for these indicators your system needs service:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can identify problems and let you know whether repair or full HVAC replacement is needed.
What you pay for HVAC installation or maintenance is determined by your system style. Common HVAC unit styles include the following:
HVAC maintenance prices differ based on the specific services needed. HVAC systems can be complex and potentially require several different services. Costs for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,860-$4,743 | |
| Hybrid Split | $3,770-$6,945 | |
| Heat Pump | $2,919-$29,743 | |
| Packaged Heating and Air | $244-$407 |
Repairing or replacing your HVAC system when needed is crucial, but can be costly. Luckily, there are steps you can take to slow the wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $61-$163 | |
| Condensor Cleaning | $1,221-$3,664 | |
| Thermostat Repair | $81-$204 | |
| Ductwork Cleaning | $391-$977 |
Knowing what makes a trustworthy HVAC company is vital for a successful installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.
Request estimates from three or more HVAC providers. Explain your issues and ask if specialists can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.
When picking an HVAC company, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states need to 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." Contractors 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 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 Air Conditioning, Refrigeration, Electrical, Heating, or Plumbing, depending on what's needed for a specific project. Contractors must have one year of work experience and must pass an exam to obtain a license. Individual cities or counties may have additional requirements. Also check a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with glowing feedback and stories of satisfied customers.
Always make sure you know the details of any project. For HVAC repairs, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test the full system after repairs are finished to verify that it’s working properly. When getting a replacement, ask your contractor to explain the new HVAC system energy efficiency, estimated installation time, brand, features, and model. Before signing a contract, you should understand how your provider will size the system appropriately for your home and the price you'll pay.
A reputable HVAC company will back its repair work and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare warranty terms between contractors and choose the company that provides the greatest protection within your budget.
Get written estimates before starting any HVAC work. The quote should cover costs for both materials and labor. Read all terms carefully before signing.
You should have your HVAC system inspected about twice annually. At the time of the inspection, your technician will inform you what services are needed. You should also schedule an inspection if you start noticing issues such as strange noises, leaks, or unusual smells. If your home has ductwork, you should have it inspected every few years.
Normally, you should schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready 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. Keep your thermostat temperature 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 windows and doors to help keep cool air in. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.
It takes around one to three days to have an HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this can take between half a day and two days. This timeline can be affected by the size of your home, how easily accessible your system is, and any issues your technician discovers.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Summerville, you'll probably want to choose a unit that's on the higher end of this range. For a house over 1,000 square feet, central air is likely to 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 Summerville, you may be able to make do with a lower-capacity furnace.
Your HVAC company might provide financing options via a third-party lender, or you might choose to obtain your own loan. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you find the best option for you.
There are several ways you can make your HVAC system more energy-efficient:
