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 having issues or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Look for these signs your system needs service:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can pinpoint problems and let you know whether repair or full HVAC replacement is the best course of action.
Your HVAC installation or maintenance cost changes depending on the type of unit. Common HVAC unit varieties include the following:
HVAC maintenance costs differ based on the specific services required. HVAC systems can be complex and potentially require several different services. Price ranges for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,880-$4,792 | |
| Hybrid Split | $3,809-$7,017 | |
| Heat Pump | $2,949-$30,053 | |
| Packaged Heating and Air | $247-$411 |
It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Fortunately, there are some steps you can take to reduce wear and tear on your HVAC.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $62-$165 | |
| Condensor Cleaning | $1,234-$3,702 | |
| Thermostat Repair | $82-$206 | |
| Ductwork Cleaning | $395-$987 |
Knowing what to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor can offer you peace of mind and ensure your system provides reliable heating and air conditioning for your home.
Contact at least three HVAC companies for quotes. Explain your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.
Look for an HVAC company that employs skilled technicians with the necessary licensure and training. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all contractors who "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.
The state of New York doesn't have state-level HVAC licensing; however, there may be local requirements, so be sure to check with your city or municipal 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 provider's reviews and complaints with organizations such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Choose a provider with glowing reviews and stories of positive service experiences.
Make sure you know the details of any project before it begins. If HVAC repairs are required, have your provider detail which parts require replacement and why. Confirm that your technician will clean and test the system after the repair to verify that everything works. When replacing your HVAC, ask the installation company to provide details on the new estimated installation time, brand, features, energy efficiency, and model. Before work begins, 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.
Good HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that provides the best protection within your budget.
Get written bids before beginning any HVAC work. The quote should outline costs for both materials and labor. Review all terms carefully before signing.
You should have your HVAC system inspected about twice yearly. Following an inspection, your technician will inform 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 system has ductwork, it should be inspected every few years.
Usually, it's a good idea to schedule inspections 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 typically sees 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 an HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this might take between half a day and two days. This timeline will be influenced by the size of your home, how easily accessible your system is, and any new issues your technician uncovers.
For a 2,000-square-foot home, try to purchase 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 to purchase an air conditioning unit with around 2.5 to 5 tons of capacity. In De Witt, a unit with a lower capacity may be sufficient. In general, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
There are several ways you can make your HVAC system more energy-efficient:
