If your home's HVAC system is malfunctioning or suffering from a lot of wear and tear, you might need an HVAC contractor for repairs or replacement. Look for these common signs that your system needs expert attention:
If you're experiencing any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and decide whether repairing or getting a new HVAC unit is the best solution.
Your HVAC installation or maintenance cost varies depending on the type of unit. Common HVAC unit types include the following:
The amount you spend on HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complex and can require different kinds of maintenance. The prices of some common jobs 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 complete repairs or full-system HVAC replacements as needed, 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 | $62-$165 | |

Knowing what makes a trustworthy HVAC company is crucial for an easy installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Get quotes from three or more HVAC providers. Describe your issues and ask if technicians can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.
It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the type of exam depends on what kind of equipment they intend to work with). Section 608 certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." All other licensing requirements are handled on a state-by-state basis.
HVAC contractors in California must be licensed by the Department of Consumer Affairs Contractors State License Board (CSLB). The CSLB considers HVAC contractors to be specialty contractors. All contractors must have four years of experience and be bonded, and contractors with employees must also meet insurance requirements. You should also check reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with glowing reviews and reports of good customer experiences.
Always make sure you understand the details of any project. For HVAC repairs, your provider should detail which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are done to verify that it’s working properly. For replacement, ask your contractor to explain the new HVAC system estimated installation time, model, brand, energy efficiency, and features. Before signing a contract, you should understand how your provider will size the system appropriately for your home and the price you'll pay.
A reputable HVAC company will back its repair services and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the provider that offers the best protection at a reasonable price.
Always get HVAC bids in writing before work begins. A thorough quote covers costs for both materials and labor. Make sure that you agree to all terms before signing the contract.
You should have your HVAC system inspected approximately twice a year. Following an inspection, your technician will tell you if any services are needed. You should also call a technician 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.
Generally, it's smart to schedule inspections 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 probably 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 door or window leaks to help keep cool air in. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.
Generally, whole-system HVAC installation or replacement takes between one and three days. Installing or replacing an air conditioning unit or a furnace may take anywhere from a few hours up to two days. The exact amount of time will depend on factors like the size of your house, 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 Montclair, you'll probably want to purchase a unit on the higher end of this range. For homes 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'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Montclair, you may be able to make do with a lower-capacity furnace.
Your HVAC company might offer financing options through a third-party lender, or you might be able to obtain your own loan. It's a good idea 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:
