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 malfunctioning or aging HVAC system probably needs attention from a professional who can make repairs or install a new unit. Keep an eye out for these common signs that your HVAC needs service:
Schedule an inspection if you notice any of these problems. A local technician can inspect your system, identify problems, and determine whether you need repairs or a new HVAC unit.
What you spend on HVAC installation or maintenance varies based on your system style. Common HVAC unit styles include the following:
HVAC maintenance costs differ depending on what services are needed. HVAC systems are complicated and might require different kinds of maintenance. Costs for common services are as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $2,091-$5,330 | |
Hybrid Split | $4,236-$7,805 | |
Heat Pump | $3,280-$33,425 | |
Packaged Heating and Air | $274-$457 |
Essential HVAC maintenance is important, but can be expensive. Luckily, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.
Service | Cost | |
---|---|---|
Filter Replacement | $69-$183 | |
Condensor Cleaning | $1,372-$4,117 | |
Thermostat Repair | $91-$229 | |
Ductwork Cleaning | $439-$1,098 |
Finding the right HVAC company is crucial for a smooth installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Request estimates from three or more HVAC providers. Describe your issues and ask if technicians can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.
Choose an HVAC company with well-trained technicians who have proper licensing and experience. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual must pass an exam (the type of exam depends on the kind of equipment they plan 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 by the state.
In California, HVAC contractors 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 are required to have four years of experience and to be bonded, and contractors with employees must also meet insurance requirements. Reviewing feedback on Google Reviews, the Better Business Bureau (BBB), Yelp, and similar sites can aid your decision. Choose a provider with stellar reviews and stories of positive experiences from customers.
Always make sure you know what a company’s process is like. When HVAC repairs are needed, ask your provider to specify which parts need replacement and explain why. Confirm that your technician will clean and test your system afterward to ensure proper operation. When replacing your HVAC, have the contractor explain the new model, features, estimated installation time, energy efficiency, and brand. Before signing paperwork, make sure you understand how your provider will determine the right system size for your home and what the price will be.
Trustworthy HVAC companies stand behind their services with warranties. Look at warranties from different companies, remembering that broader coverage is better. Look for the company that offers the most coverage for a reasonable price.
Always get HVAC estimates in writing before work begins. A comprehensive quote covers costs for both materials and labor. Ensure that you agree to all terms before signing the contract.
You should have your HVAC system inspected about twice yearly. Following an inspection, your technician will tell you what services are required. You should also have your system inspected if you start noticing issues such as leaks, unusual smells, or strange noises. If your system has ductwork, you should have it inspected every few years.
Normally, it's best to have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared for the summer and winter, when it likely sees the most use.
You can save energy throughout the year by reducing the amount of work it takes 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 once. You could also consider installing a smart thermostat.
Generally, HVAC installation or replacement takes one to three days for the entire system. 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 be based on factors 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. If your home is larger than 1,000 square feet, central air will usually be more effective than window units for cooling.
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).
Your HVAC company might have financing options via a third-party lender, or you might 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 several ways you can make your HVAC system more energy-efficient:
