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 professional attention from a technician who can make repairs or install a new unit. Watch out for these common signs that your HVAC needs service:
If you see any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and let you know whether whether repairing or getting a new HVAC unit is the best solution.
The price of HVAC installation or maintenance varies depending on the kind of unit you have. Common types of HVAC units include the following:
The cost of HVAC maintenance also depends on what kind of work you're having done. HVAC systems are complicated and may require different kinds of maintenance. The prices of some common jobs are as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $1,891-$4,820 | |
Hybrid Split | $3,831-$7,058 | |
Heat Pump | $2,966-$30,226 | |
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 ways to minimize progressive deterioration and reduce the frequency of breakdowns.
Service | Cost | |
---|---|---|
Filter Replacement | $62-$165 | |
Condensor Cleaning | $1,241-$3,723 | |
Thermostat Repair | $83-$207 | |
Ductwork Cleaning | $397-$993 |
Knowing what makes a trustworthy 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.
Contact at least three HVAC companies for quotes. Explain the issues and have specialists visit to inspect your system if possible. Compare the contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.
Look for an HVAC company that employs skilled technicians with the necessary training and licenses. HVAC contractors in all states must 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." An individual 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 at the state level.
HVAC contractors in Virginia need to have a contractor license with an HVAC specialization from the Department of Professional and Occupational Regulation. A valid Master HVAC Tradesman License (which has its own experience and education requirements) is necessary to apply. Licenses be class A, B, or C.
Always make sure you understand the details of any project. For HVAC repairs, your provider should specify which parts need replacement and why. Confirm that your technician will clean and test the full system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, have the contractor explain the new estimated installation time, model, brand, features, and energy efficiency. Before signing paperwork, be sure you understand how your provider will determine the right system size for your home and what the price will be.
Good HVAC companies offer warranties on service and equipment installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that provides the best protection within your budget.
Get written estimates before starting any HVAC work. The quote should outline costs for both labor and materials. Review all terms carefully before signing.
Typically, your HVAC system should be inspected twice a year. After that inspection, your technician will tell you what services are needed. You should also have your system inspected and serviced if you notice any new issues, such as leaks, unusual smells, or strange noises. If your home has ductwork, it should be serviced every few years.
The best times to have an HVAC inspection are during the spring and fall. Technicians are less busy during these times, which makes it easier to get an appointment. This also helps get your system ready for the summer and winter, when it typically gets 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 you can, and try to adjust it only a few degrees at once. You may also consider purchasing a smart thermostat.
It takes roughly one to three days to have an HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this might take between half a day and two days. This timeline will be determined by the size of your home, the accessibility of your system, 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. For a house over 1,000 square feet, central air will 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).
Your HVAC company may 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 your HVAC company and a financial advisor 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:
