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 old, it likely needs servicing or replacement from an HVAC company. Look for these indicators your system needs service:
If you notice any of the above, have a local HVAC technician inspect your system. They can diagnose problems and let you know whether repair or full HVAC replacement is the best course of action.
HVAC installation or maintenance costs vary depending on your system. Common HVAC unit varieties include the following:
HVAC maintenance costs vary depending on the particular service needed. HVAC systems are complicated and can require different maintenance services. Prices for common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,947-$4,962 | |
| Hybrid Split | $3,944-$7,266 | |
| Heat Pump | $3,054-$31,119 | |
| Packaged Heating and Air | $256-$426 |
It's important to take care of HVAC repairs and replacements in a timely manner, 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 | $64-$170 | |
| Condensor Cleaning | $1,278-$3,833 | |
| Thermostat Repair | $85-$213 | |
| Ductwork Cleaning | $409-$1,022 |
Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling in your home.
Contact at least three HVAC providers for quotes. Explain the issues and have technicians visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand payment upfront.
Look for an HVAC company that employs qualified technicians who have the necessary training and licenses. In all states, HVAC contractors must 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." 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.
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 a High Pressure Boiler Operating Engineer or Oil Burning Equipment Installer license from the NYC Department of Buildings, or a Certificate of Qualification for Refrigerating System Operating Engineer from the Fire Department of New York. Checking reviews on Yelp, the Better Business Bureau (BBB), Google Reviews, and similar sites can assist your decision. Choose a provider with great reviews and reports of positive customer experiences.
Make sure you know the details of your project before starting. For HVAC repairs, have your provider list which parts require 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 your contractor to explain the new HVAC system model, brand, features, energy efficiency, and estimated installation time. Before starting the project, you should understand how your provider will size the system appropriately for your home and the price you'll pay.
A trustworthy HVAC company will back its repair services and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review the fine print for each contractor and choose the provider that offers the best protection within your budget.
Get a written proposal before HVAC work starts. A comprehensive quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.
You should have your HVAC system inspected about twice yearly. After completing their inspection, your technician will tell you if any services are required. You should also have your system inspected if you notice new issues such as strange noises, unusual smells, or leaks. If your system has ductwork, it should be inspected every few years.
Generally, it's a good idea to schedule inspections in the spring and fall, as these times tend to be less busy. This also helps get your system ready 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 — only increase or decrease it a few degrees at a time. If you're able to, try switching to a smart thermostat.
Generally, whole-system HVAC installation or replacement takes between one and three days. Installing or replacing a furnace or air conditioning unit may take anywhere from a few hours up to two days. The exact amount of time will depend on factors like how large your home is, how easily accessible different areas are, and whether your technician finds any problems.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Geneva, you'll probably be fine with a unit on the lower end of this range. If your home is larger than 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 provide financing options through a third-party lender, or you might choose to obtain your own loan. 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 several ways you can make your HVAC system more energy-efficient:
