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 faulty or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Look for these signs your system needs service:
If you see any of these HVAC issues, you should have a technician inspect your system. A local professional can identify problems and determine whether fixing or replacing your HVAC unit is the best solution.
HVAC installation or maintenance prices change depending on your system. Common HVAC unit types include the following:
HVAC maintenance costs vary depending on what services are needed. HVAC systems are complex and might require different maintenance services. Prices for some common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,890-$4,817 | |
| Hybrid Split | $3,829-$7,054 | |
| Heat Pump | $2,965-$30,211 | |
| Packaged Heating and Air | $248-$414 |
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-$165 | |
| Condensor Cleaning | $1,241-$3,722 | |
| Thermostat Repair | $83-$207 | |
| Ductwork Cleaning | $397-$992 |
Knowing the indicators of a reliable HVAC company is key for a smooth repair or installation. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.
Get quotes from at least three HVAC providers. Explain your issues and ask if technicians can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid contractors that pressure you or demand payment before work.
When selecting an HVAC provider, choose one with technicians that have the proper training, licenses, and experience. In all states, HVAC contractors 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." Contractors 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 California, HVAC contractors 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. Reviewing feedback on Yelp, the Better Business Bureau (BBB), Google Reviews, and similar sites can aid your decision as well. Choose a provider with great reviews and reports of positive customer experiences.
Always make sure you know the details of your project. For HVAC repairs, your provider should list which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are done to verify that it’s working properly. When replacing your HVAC, request that the installation company describe the new brand, features, model, estimated installation time, and energy efficiency. Before work starts, ask how your provider plans to accurately size the unit for your home and how much it will cost.
Reputable HVAC companies back their services with warranties. Look at warranties from different companies, bearing in mind that broader coverage is better. Look for the company that offers the most coverage for a reasonable price.
Get written estimates before starting any HVAC work. The quote should cover costs for both materials and labor. Review all terms carefully before signing.
You should have your HVAC system inspected twice yearly. At the time of the inspection, your technician will inform you what services are needed. You should also schedule an inspection if you notice new issues such as unusual smells, strange noises, or leaks. If your home has ductwork, it should be inspected every few years.
Generally, it's smart to schedule inspections in the spring and fall, as these times tend to be less busy. This also helps get your system ready for the summer and winter, when it typically sees 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 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.
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 depend on things like the size of your home, how easily accessible different sections are, and whether your technician finds any problems.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Crestline, you'll probably want to choose a unit that's on the higher end of this range. For a house over 1,000 square feet, central air will usually be more effective for cooling than window units.
For a 2,000-square-foot home, you should also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Crestline, you may be able to make do with a lower-capacity furnace.
There are several ways you can make your HVAC system more energy-efficient:
