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:
If your HVAC system is broken or getting old, it likely needs repairs or replacement from an HVAC company. Look for these signs your system needs service:
Arrange an inspection if you notice any of these problems. A local technician can evaluate your system, detect problems, and decide whether you need repairs or a new HVAC unit.
HVAC installation or maintenance costs change depending on your system. Common HVAC unit varieties include the following:
HVAC maintenance costs differ based on the specific services needed. HVAC systems can be complicated and potentially require a number of services. Costs for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $2,023-$5,156 | |
| Hybrid Split | $4,099-$7,551 | |
| Heat Pump | $3,173-$32,337 | |
| Packaged Heating and Air | $266-$443 |
HVAC upkeep is important, but can be expensive. Fortunately, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $66-$177 | |
| Condensor Cleaning | $1,328-$3,983 | |
| Thermostat Repair | $89-$221 | |
| Ductwork Cleaning | $425-$1,062 |
Knowing what to look for in an HVAC company is crucial for a successful project. Look for an experienced, licensed contractor that can give you peace of mind and ensure your system provides reliable heating and air conditioning for your home.
Request estimates from three or more HVAC contractors. Explain your issues and ask if specialists can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.
Look for an HVAC company that employs skilled technicians who have the necessary licensure and training. 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." Contractors must pass an exam (the type of exam depends on what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled on a state-by-state basis.
HVAC contractors in New Jersey are required to be licensed by the Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors. Contractors must be bonded and must participate in ongoing education. Individuals who operate an HVAC business must also have general liability insurance. Reviewing feedback on Google Reviews, the Better Business Bureau (BBB), Yelp, and similar sites can aid your decision as well. Choose a company with stellar reviews and reports of positive experiences from customers.
Always make sure you know the details of a planned project. When HVAC repairs are required, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are done to ensure that it’s working properly. When replacing your HVAC, ask the contractor to provide details on the new estimated installation time, features, energy efficiency, brand, and model. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.
Trustworthy HVAC companies back their services with warranties. Look at warranties from different companies, keeping in mind that broader coverage is better. Look for the company that provides the most coverage for a reasonable price.
Always get quotes for HVAC service in writing before work begins. An itemized quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.
Normally, you should have your HVAC system inspected twice a year. After that inspection, your HVAC technician will tell you what, if any, services are needed. You should also have your system inspected and serviced if you start to notice any issues, such as strange noises, unusual smells, or leaks. If you have ductwork in your home, it should be serviced every few years.
The best times of the year to have your HVAC system inspected are during the spring and fall. Technicians are often less busy during these times, making it easier to get an appointment. This also ensures that your system is ready for the summer and winter, when it typically sees the most use.
You can save energy throughout the year by reducing the amount of power your HVAC system uses to maintain the temperature of your home. 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 a time. You may also consider purchasing a smart thermostat.
It takes roughly one to three days to have your 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 can be influenced by the size of your house, the accessibility of your system, and any new issues your technician discovers.
For a 2,000-square-foot home, you should look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units).
For a 2,000-square-foot home, you'll also want an air conditioning unit with around 2.5 to 5 tons of capacity. In general, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company might provide financing options via a third-party lender, or you might choose 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 a number of ways you can make your HVAC system more energy-efficient:
