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 near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Look for these signs your system needs service:
If you notice any of the above, have a local HVAC technician inspect your system. They can diagnose problems and determine whether repair or full HVAC replacement is the better solution.
What you spend on HVAC installation or maintenance depends on your system type. Common HVAC unit styles include the following:
The price of HVAC maintenance also depends on what kind of work being done. HVAC systems are complicated and can require different kinds of maintenance. The cost of some common repairs is as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,901-$4,847 | |
| Hybrid Split | $3,853-$7,098 | |
| Heat Pump | $2,983-$30,398 | |
| Packaged Heating and Air | $250-$416 |
It’s important to make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $62-$166 | |
| Condensor Cleaning | $1,248-$3,745 | |
| Thermostat Repair | $83-$208 | |
| Ductwork Cleaning | $399-$999 |
Knowing what to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and make sure your system provides reliable air conditioning and heating for your home.
Contact at least three HVAC providers for quotes. Describe the issues and have specialists visit to inspect your HVAC system if possible. Compare the companies' explanations, solutions, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand payment upfront.
When picking an HVAC company, choose one with technicians that have the right 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." 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 at the state level.
In Texas, HVAC contractors are required to be licensed by the Texas Department of Licensing and Regulation. Contractors must have at least four years of experience within the past six years and must show proof of insurance. An individual can also be a registered technician, which has no experience requirements, or a certified technician, which requires two years of experience. Both registered and certified technicians must be supervised by a licensed contractor. Checking reviews on the Better Business Bureau (BBB), Yelp, Google Reviews, and similar sites can help your decision. Choose a company with stellar reviews and stories of positive customer experiences.
Always make sure you understand the details of your project. When HVAC repairs are required, your provider should specify which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are done to ensure that it’s working properly. When getting a replacement, ask your contractor to explain the new HVAC system brand, model, estimated installation time, features, and energy efficiency. Before signing a contract, you should understand how your provider will size the system appropriately for your home and the price you'll pay.
Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that offers the best protection for a fair price.
Get written estimates before beginning HVAC work. The quote should cover costs for both labor and materials. Read all terms carefully before signing.
Typically, you should have your HVAC system inspected twice a year. After that inspection, your HVAC technician will tell you what, if any, services are required. You should also have your system inspected and serviced if you notice any new issues, such as unusual smells, strange noises, or leaks. If your home has ductwork, it should be serviced every few years.
The best times of the year to have your HVAC system inspected are the spring and fall. Technicians are generally less busy during these times, making it easier to get an appointment. This also ensures that your system is ready for the summer and winter, which is when it normally gets 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.
Generally, HVAC installation or replacement takes one to three days for the entire system. 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 things like how large your home is, how easily accessible different sections are, and whether your technician finds any problems.
For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. In Jacksonville, you'll probably want to choose a unit that's on the higher end of this range. If your home is larger than 1,000 square feet, central air is likely to be more effective for cooling than window units.
For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Jacksonville, you might be able to make do with a lower-capacity furnace.
Usually, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer financing, you could consider taking out your own loan. Be sure to talk to a financial advisor and your HVAC company to determine what options are available to you and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
