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 home's HVAC system is malfunctioning or getting old, you may need to hire an HVAC contractor for maintenance or replacement. Look for these common signs that your system requires expert attention:
These HVAC red flags indicate that you should have your system evaluated. A local technician can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.
The price of HVAC installation or maintenance changes depending on the type of unit you have. Common types of HVAC units include the following:
HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complex and can require different maintenance services. Costs for common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,936-$4,936 | |
| Hybrid Split | $3,923-$7,228 | |
| Heat Pump | $3,038-$30,953 | |
| Packaged Heating and Air | $254-$424 |
Taking care of necessary HVAC repairs and replacements when needed is important, but can be costly. Luckily, there are steps you can take to reduce gradual wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $64-$169 | |
| Condensor Cleaning | $1,271-$3,813 | |

Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.
Get quotes from at least three HVAC companies. Explain your issues and ask if technicians can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.
When selecting an HVAC company, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory 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 by the state.
There is no state-level HVAC licensing in New York; however, many cities and municipalities have their own requirements, so be sure to check with your local government. For example, in some cases, a technician may need an Oil Burning Equipment Installer or High Pressure Boiler Operating Engineer license from the NYC Department of Buildings, or a Certificate of Qualification for Refrigerating System Operating Engineer from the Fire Department of New York. You should also check a company's reviews and complaints with organizations such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Choose a company with positive reviews and a history of good customer service.
Make sure you understand the details of your project before starting. For HVAC repairs, have your provider list which parts need replacement and why. Get confirmation that your technician will clean and test your system after the repair to verify that everything works. When getting a replacement, ask the contractor to explain the new HVAC system model, estimated installation time, brand, energy efficiency, and features. Before starting the project, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.
A reputable HVAC company will back its repair services and installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare warranty terms between contractors and choose the company that provides the best protection within your budget.
Get a written estimate before HVAC work begins. A full quote includes both materials and labor costs. Make sure you understand and agree to all terms before signing the contract.
Generally, your HVAC system should be inspected twice a year. After that inspection, your HVAC technician will tell you what, if any, services are needed. You should also have an inspection if you start to notice any issues, such as leaks, unusual smells, or strange noises. If you have ductwork in your home, it should be serviced every few years.
The best times of the year to have an HVAC inspection are during the spring and fall. Technicians are 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 gets the most use.
You can save energy during the winter by reducing how much power your HVAC system uses to heat your home. Keep your thermostat as low as is comfortable and avoid making drastic temperature changes — increase or decrease it a few degrees at a time. If you can, try switching to a smart thermostat.
It takes between one and three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this may take anywhere from a few hours up to two days. This timeline will be affected by the size of your house, the accessibility of your system, and any issues your technician runs into.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Ballston, you'll probably be fine with a unit that's on the lower end of this range. For homes over 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).
Normally, HVAC financing is offered through a third-party lender. If your HVAC company doesn't have financing options, you could consider taking out your own loan. Be sure to talk to a financial advisor and your HVAC company to find out what options are available to you and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
