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:
A faulty or aging HVAC system probably needs professional attention from a technician who can make fixes or install a new unit. Watch out for these common signs that your HVAC needs service:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can pinpoint problems and determine whether repair or full HVAC replacement is the best course of action.
The price of HVAC installation or maintenance changes depending on the type of unit you have. Common types of HVAC units include the following:
The cost of HVAC maintenance also depends on the kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The cost of some common repairs is 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 |
Fixing your HVAC by repairing or replacing parts when needed is crucial, but can be expensive. Luckily, there are steps you can take to reduce gradual wear and tear on your system.
Service | Cost | |
---|---|---|
Filter Replacement | $70-$185 | |
Condensor Cleaning | $1,391-$4,173 | |
Thermostat Repair | $93-$232 | |
Ductwork Cleaning | $445-$1,113 |
Knowing what to look for in an HVAC company is crucial for a successful project. Look for an experienced, licensed contractor that can offer you peace of mind and ensure your system provides reliable air conditioning and heating for your home.
Contact at least three HVAC companies for quotes. Explain your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.
It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor 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). 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. You should also look at reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Choose a company with glowing reviews and reports of great customer experiences.
Always make sure you understand what a company’s process looks like. When HVAC repairs are needed, ask your provider to specify which parts need replacement and why. Confirm that your technician will clean and test your system afterward to guarantee proper operation. When replacing your HVAC, ask the provider to explain the new model, features, estimated installation time, energy efficiency, and brand. Before work starts, be sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.
Trustworthy HVAC companies back their services with warranties. Compare warranties from different companies, keeping in mind that more comprehensive coverage is better. Look for the company that offers the most coverage for a reasonable price.
Always get HVAC bids in writing before work begins. A thorough quote will cover costs for both labor and materials. Confirm that you understand all terms before signing the contract.
You should have your HVAC system inspected approximately twice yearly. After completing their inspection, your technician will inform you if any services are required. You should also schedule an inspection if you start noticing issues such as leaks, strange noises, or unusual smells. If your home has ductwork, you should have it inspected every few years.
Generally, it's a good idea to have your HVAC system inspected 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 throughout the year by making it easier for your HVAC system to maintain your home's temperature. During all seasons, keep your thermostat as close to the outside temperature as you can, and try to adjust it only a few degrees at a time. You might also consider a smart thermostat.
It takes roughly one to three days to have an HVAC system installed or replaced. If you need just a furnace or a single air conditioning unit, this can take anywhere from a few hours up to two days. This timeline will be determined by the size of your home, the accessibility of your system, and any issues your technician uncovers.
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 San Carlos, you may be able to make do with a furnace on the lower end of this range.
For a 2,000-square-foot home, you'll also want an air conditioning unit with between 2.5 and 5 tons of capacity. Usually, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company may provide financing options through a third-party lender, or you may choose to obtain your own loan. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you find the best option for you.
There are several ways you can make your HVAC system more energy-efficient:
