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An HVAC system that's not working properly or outdated likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:
If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.
HVAC installation or maintenance prices vary depending on your system. Common HVAC unit varieties include the following:
HVAC maintenance prices vary depending on what services are needed. HVAC systems are complex and may require different maintenance services. Fees for some common services are as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $1,957-$4,990 | |
Hybrid Split | $3,966-$7,307 | |
Heat Pump | $3,071-$31,292 | |
Packaged Heating and Air | $257-$428 |
Essential HVAC maintenance is important, but can be expensive. Thankfully, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.
Service | Cost | |
---|---|---|

Condensor Cleaning | $1,285-$3,855 | |
Thermostat Repair | $86-$214 | |

Knowing what makes a trustworthy HVAC company is vital for an easy installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Contact at least three HVAC providers for quotes. Describe your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.
Look for an HVAC company that employs qualified technicians who have the necessary licensure and training. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all contractors who "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 by the state.
HVAC contractors in California must be licensed by the Department of Consumer Affairs Contractors State License Board (CSLB). HVAC contractors are considered specialty contractors by the CSLB. All contractors must have four years of experience and be bonded. Contractors with employees must also meet insurance requirements. Also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with glowing feedback and good customer testimonials.
Make sure you know the details of any project before starting. If HVAC repairs are required, have your provider detail which parts need replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. When getting a replacement, ask your contractor to explain the new HVAC system features, brand, model, estimated installation time, and energy efficiency. Before work begins, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.
Reliable HVAC companies offer warranties on repairs and equipment 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 bids before starting HVAC work. The quote should include costs for both materials and labor. Review all terms carefully before signing.
Generally, you should have your HVAC system inspected twice a year. After an inspection, your HVAC technician will tell you what services are needed. You should also have an inspection if you notice any new issues, such as unusual smells, leaks, or strange noises. If your home has ductwork, it should be serviced every few years.
The best times to have an HVAC inspection 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 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 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, ensure that your attic is well ventilated to avoid trapping excess heat in your home.
Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing an air conditioning unit or a furnace takes anywhere from about half a day up to two days. The exact amount of time will vary depending on things like the size of your home, how easily accessible different parts of the system are, and whether your technician finds 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 National City, 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 around 2.5 to 5 tons of capacity. In National City, you'll likely need something on the higher end of this range. In general, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Typically, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer these options, 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 several ways you can make your HVAC system more energy-efficient:
