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 see any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and decide whether fixing or replacing your HVAC unit is the correct solution.
The cost of HVAC installation or maintenance will differ depending on the type of unit you have. Common varieties of HVAC units include the following:
HVAC maintenance prices differ based on the specific services needed. HVAC systems can be complicated and potentially require several different services. Fees for typical jobs are as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $1,882-$4,798 | |
Hybrid Split | $3,814-$7,026 | |
Heat Pump | $2,953-$30,089 | |
Packaged Heating and Air | $247-$412 |
Essential HVAC maintenance is important, but can be pricey. Thankfully, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.
Service | Cost | |
---|---|---|
Filter Replacement | $62-$165 | |
Condensor Cleaning | $1,236-$3,707 | |
Thermostat Repair | $82-$206 | |
Ductwork Cleaning | $395-$988 |
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 ensure your system provides reliable heating and air conditioning for your home.
Get quotes from three or more HVAC companies. Explain your issues and ask if specialists can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.
When hiring an HVAC company, choose one with technicians that have the right training, licenses, and experience. HVAC contractors in all states 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." 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 by the state.
Missouri doesn't have state-level licensing requirements for HVAC contractors; however, most municipalities have local requirements. It's always a good idea to check with your local government to understand requirements for licenses such as HVAC Contractor or HVAC Journeyman Contractor. You can also verify that a company holds a valid business license. Always check a company's reviews and complaints with organizations such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Choose a company with glowing reviews and stories of positive service experiences.
Make sure you understand the details of any project before it begins. When getting HVAC repairs, have your provider specify which parts need replacement and why. Get confirmation that your technician will clean and test the entire system after the repair to ensure that everything works. When getting a replacement, ask your contractor to explain the new HVAC system model, estimated installation time, features, energy efficiency, and brand. Before signing a contract, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.
A reputable HVAC company will stand behind its repair services and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review the fine print for each contractor and choose the company that provides the greatest protection at a reasonable price.
Always get estimates for HVAC service in writing before committing to a provider. A comprehensive quote should cover both materials and labor. Make sure you review all terms before signing a contract.
You should have your HVAC system inspected twice a year. After completing their inspection, your technician will tell you if any services are required. You should also schedule an inspection 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.
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 typically sees the most use.
You can save energy throughout the year by reducing the amount of work it takes for your HVAC system to maintain the temperature of your home. During all seasons, keep your thermostat as close to the outside temperature as is comfortable, and avoid making drastic changes — adjust it only a few degrees at a time. You might also consider purchasing a smart thermostat.
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 may take anywhere from a few hours up to two days. This timeline will be affected by the size of your home, how easily accessible your system is, and any new issues your technician uncovers.
Your HVAC company may provide financing options through a third-party lender, or you may be able to obtain a loan on your own. It's smart to discuss payment options with your HVAC company and a financial advisor to make sure that you're choosing the best option for you.
There are several ways you can make your HVAC system more energy-efficient:
