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:
An HVAC system that's broken or past its lifespan likely needs professional attention for repairs or replacement. Watch for these indicators that your system needs service:
Book an inspection if you notice any of these problems. A local technician can inspect your system, detect problems, and determine whether you need to fix or replace your HVAC.
Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit types include the following:
HVAC maintenance costs differ based on the specific services needed. HVAC systems can be complicated and potentially require several different services. Costs for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,813-$4,622 | |
| Hybrid Split | $3,674-$6,768 | |
| Heat Pump | $2,845-$28,986 | |
| Packaged Heating and Air | $238-$397 |
It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Fortunately, there are some steps you can take to reduce wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $60-$159 | |
| Condensor Cleaning | $1,190-$3,571 | |
| Thermostat Repair | $79-$198 | |
| Ductwork Cleaning | $381-$952 |
Knowing what to look for in an HVAC company is important for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and make sure your system provides reliable air conditioning and heating for your home.
Get quotes from three or more HVAC companies. Explain your issues and ask if specialists can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.
It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. In all states, HVAC contractors have federal requirements set by 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 plan 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 at the state level.
HVAC contractors in South Carolina are required to be licensed as mechanical contractors by the South Carolina Department of Labor, Licensing and Regulation Contractor's Licensing Board. This license can have multiple specialities, such as Electrical, Heating, Plumbing, Refrigeration, or Air Conditioning, depending on what's required for a specific project. Contractors need to have one year of work experience and must pass an exam to be licensed. Your city or county may have additional requirements. Always check a company's reviews and complaints with organizations such as Yelp, the Better Business Bureau (BBB), and Google Reviews. You want to hire a company with positive reviews and a history of good customer service.
Make sure you know the details of your project before it begins. When getting HVAC repairs, have your provider specify which parts need replacement and why. Confirm that your technician will clean and test the entire system after the repair to verify that everything works. When replacing your HVAC, ask your installation company to provide details on the new features, model, brand, energy efficiency, and estimated installation time. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.
Reputable HVAC companies back their work with warranties. Look at warranties from different companies, while remembering that broader coverage is better. Look for the company that offers the most coverage for a reasonable price.
Get a written quote before HVAC work starts. A full quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.
You should have your HVAC system inspected twice annually. After completing their inspection, your technician will tell you what services are needed. You should also call a technician if you notice new issues such as leaks, strange noises, or unusual smells. If your system has ductwork, it should be inspected every few years.
Normally, it's a good idea to schedule inspections in the spring and fall, as technicians tend to be less busy at these times. 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. Keep your thermostat temperature as close to the outside temperature as you comfortably can, and 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 roughly 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 anywhere from a few hours up to two days. This timeline will be affected by the size of your house, the accessibility of your system, and any issues your technician uncovers.
For a 2,000-square-foot home, you should look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Aiken, 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 to look for an air conditioning unit with around 2.5 to 5 tons of capacity. In Aiken, you'll likely want something on the higher end of this range. Generally, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company might offer financing options through a third-party lender, or you might choose to obtain your own loan. It's a good idea to discuss payment options with your HVAC company and a financial advisor to make sure that you're choosing the best option for you.
