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 home's HVAC system isn't working correctly or nearing the end of its lifespan, you might need an HVAC contractor for repairs or replacement. Watch for these common signs that your system needs professional attention:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can diagnose problems and determine whether repair or full HVAC replacement is the best course of action.
The cost of HVAC installation or maintenance will differ depending on the kind of unit you have. Common types of HVAC units include the following:
HVAC maintenance costs differ based on the specific services needed. HVAC systems can be complicated and potentially require a number of services. Fees for typical jobs are as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $2,119-$5,402 | |
Hybrid Split | $4,294-$7,911 | |
Heat Pump | $3,325-$33,879 | |
Packaged Heating and Air | $278-$464 |
It’s important to take care of HVAC repairs and replacements when they are required, though they can be expensive. The good news is that homeowners have ways to minimize progressive deterioration and reduce the frequency of breakdowns.
Service | Cost | |
---|---|---|
Filter Replacement | $70-$185 | |
Condensor Cleaning | $1,391-$4,173 | |
Thermostat Repair | $93-$232 | |
Ductwork Cleaning | $445-$1,113 |
Knowing the right things to look for in an HVAC company is key for a smooth installation or repair. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.
Contact at least three HVAC companies for quotes. Describe your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand upfront payment.
Look for an HVAC company that employs skilled technicians with 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 mandatory 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.
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, and contractors with employees must also meet insurance requirements. Always check a provider's reviews and complaints with organizations such as Yelp, Google Reviews, and the Better Business Bureau (BBB). You'll want to select a provider with positive reviews and a history of good customer service.
Always make sure you know the details of any project. For HVAC repairs, your provider should specify which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are done to ensure that it’s working properly. When replacing your HVAC, have the provider describe the new model, energy efficiency, features, brand, and estimated installation time. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.
Reputable HVAC companies back their work with warranties. Compare warranties from different companies, keeping in mind that broader coverage is better. Look for the company that provides the most coverage for a fair price.
Always get quotes for HVAC service in writing before work begins. A comprehensive quote should cover both labor and materials. Make sure you review all terms before signing a contract.
You should have your HVAC system inspected twice a year. After the inspection, your technician will inform you if any services are needed. You should also schedule an inspection if you notice new issues such as leaks, unusual smells, or strange noises. If your home has ductwork, you should have it inspected every few years.
Usually, 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 get your system ready for the summer and winter, when it likely sees the most use.
You can save energy throughout the year by making it easier for your HVAC system to maintain your home's temperature. Always 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 may also consider installing a smart thermostat.
Generally, HVAC installation or replacement takes between one and 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 the size of your home, how easily accessible different parts of the system are, and whether your technician runs into any problems.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will 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 Foster City, you may be able to make do with a lower-capacity furnace.
Your HVAC company might offer financing options via a third-party lender, or you may choose to obtain a loan on your own. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you're choosing the best option for you.
There are a number of ways you can make your HVAC system more energy-efficient:
