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 not working properly or past its lifespan likely needs professional attention for maintenance or replacement. Watch for these indicators that your system needs service:
Arrange an inspection if you notice any of these issues. A local technician can inspect your system, detect problems, and figure out whether you need repairs or a new HVAC unit.
HVAC installation or maintenance costs vary depending on your system. Common HVAC unit varieties include the following:
HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complex and might require different kinds of maintenance. Prices for common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $2,006-$5,115 | |
| Hybrid Split | $4,066-$7,490 | |
| Heat Pump | $3,148-$32,077 | |
| Packaged Heating and Air | $263-$439 |
It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Thankfully, there are some steps you can take to reduce wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $66-$176 | |
| Condensor Cleaning | $1,317-$3,951 | |
| Thermostat Repair | $88-$220 | |
| Ductwork Cleaning | $421-$1,054 |
Knowing the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can keep your system running efficiently, providing you with effective heating and cooling in your home.
Get quotes from three or more HVAC providers. Describe your issues and ask if technicians can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.
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, an individual 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 by the state.
HVAC contractors in New Jersey are required to be licensed by the Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors. All contractors must be bonded and must participate in continuing education, and individuals who operate an HVAC business must have general liability insurance. You should also check a company's reviews and complaints on sites such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Pick a company with positive feedback and stories of satisfied customers.
Always make sure you understand what a company’s process is like. When HVAC repairs are needed, ask your provider to list which parts require replacement and explain why. Confirm that your technician will clean and test your system afterward to ensure proper operation. When replacing your HVAC system, ask your contractor to provide details on the new energy efficiency, estimated installation time, brand, model, and features. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.
Reputable HVAC companies back their services with warranties. Look at warranties from different companies, keeping in mind that more comprehensive coverage is better. Look for the provider that offers the most coverage for a reasonable price.
Get a written proposal before HVAC work starts. A comprehensive quote includes both labor and material costs. Make sure you understand and accept all terms before signing the contract.
You should have your HVAC system inspected approximately twice a year. At the time of the inspection, your technician will tell you what 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, it should be inspected every few years.
Usually, you should have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system 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 your home's temperature. During all seasons, keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at a time. You might also consider purchasing a smart thermostat.
Generally, whole-system HVAC installation or replacement takes one to three days. 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 depend on things like how large your home is, how easily accessible different sections are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. 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'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).
Your HVAC company might offer financing options via a third-party lender, or you might be able to obtain a loan on your own. It's a good idea 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 a number of ways you can make your HVAC system more energy-efficient:
