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An HVAC system that's broken or outdated likely needs professional attention for repairs or replacement. Watch for these indicators that your system needs service:
These HVAC red flags indicate that you should have your system evaluated. A local technician can complete an inspection, identify problems, and recommend repairing or replacing your HVAC unit.
Your HVAC installation or maintenance cost varies depending on the style of unit. Common HVAC unit varieties include the following:
The cost of HVAC maintenance also varies depending on the kind of work you're having done. HVAC systems are complex and might require different kinds of maintenance. The prices of some common jobs are as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $2,094-$5,338 | |
Hybrid Split | $4,243-$7,817 | |
Heat Pump | $3,285-$33,475 | |
Packaged Heating and Air | $275-$458 |
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 ways to minimize progressive deterioration and reduce the frequency of breakdowns.
Service | Cost | |
---|---|---|
Filter Replacement | $69-$183 | |
Condensor Cleaning | $1,375-$4,124 | |
Thermostat Repair | $92-$229 | |
Ductwork Cleaning | $440-$1,100 |
Finding the right HVAC company is key for a successful installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.
Contact at least three HVAC providers for quotes. Describe the issues and have technicians visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid contractors that pressure you or demand payment upfront.
When hiring an HVAC provider, choose one with technicians that have the right training, licenses, and experience. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all technicians who "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 the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.
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 are required to have four years of experience and to be bonded, and contractors with employees must also meet insurance requirements. Checking reviews on Google Reviews, the Better Business Bureau (BBB), Yelp, and similar sites can assist your decision as well. Choose a company with stellar reviews and stories of positive experiences from customers.
Always make sure you understand the details of your project. For HVAC repairs, your provider should detail which parts need replacement and why. Confirm that your technician will clean and test the full system after repairs are completed to ensure that it’s working properly. When replacing your HVAC, request that the installation company describe the new energy efficiency, brand, features, estimated installation time, and model. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.
Reliable HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers the most comprehensive protection for a fair price.
Get a written proposal before HVAC work starts. A full quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.
You should have your HVAC system inspected approximately twice yearly. Following an inspection, your technician will inform you if any services are needed. You should also schedule an inspection if you notice new issues such as unusual smells, leaks, or strange noises. If your system has ductwork, it should be inspected every few years.
Generally, it's a good idea 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 typically sees the most use.
You can save energy during the summer by reducing the amount of power your HVAC system uses to keep your home cool. Set your thermostat as close to the outside temperature as you can, and try to avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any leaks around your doors and windows to help keep cool air in. Similarly, make sure your attic is well ventilated to avoid trapping excess heat in your home.
It takes between one and three days to have an HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this might take anywhere from a few hours up to two days. This timeline can be influenced by the size of your home, how easily accessible your system is, and any new issues your technician runs into.
For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. In Castro Valley, you'll probably want to purchase a unit on the higher end of this range. For a house over 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 should also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Castro Valley, you may be able to make do with a lower-capacity furnace.
Usually, HVAC financing is through a third-party lender. If your HVAC company doesn't offer financing, you may consider taking out your own loan. Be sure to speak with your HVAC company and a financial advisor to determine what options are available and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
