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 faulty or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Watch for these indicators your system needs service:
If you notice any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and determine whether fixing or replacing your HVAC unit is the best solution.
HVAC installation or maintenance costs vary depending on your system. Common HVAC unit types include the following:
HVAC expenses vary based on the services needed. HVAC systems are complex and may need several types of maintenance. Costs for common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,736-$4,426 | |
| Hybrid Split | $3,518-$6,481 | |
| Heat Pump | $2,724-$27,754 | |
| Packaged Heating and Air | $228-$380 |
Fixing your HVAC by repairing or replacing parts when needed is crucial, but can be expensive. Fortunately, there are steps you can take to minimize wear and tear over time on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $57-$152 | |
| Condensor Cleaning | $1,140-$3,419 | |
| Thermostat Repair | $76-$190 | |
| Ductwork Cleaning | $365-$912 |
Knowing the right things to look for in an HVAC company is key for a smooth repair or installation. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent coolig and heating year-round.
Request estimates from at least three HVAC contractors. Explain your issues and ask if technicians can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid contractors that pressure you or demand payment before work.
Choose an HVAC company with skilled technicians who have appropriate licensing and experience. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of exam depends on what kind of equipment they plan 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 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 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. 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.
It’s important to understand what the work process will look like. For HVAC repairs, the company should list the specific parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to make sure everything is operating properly. When replacing your HVAC, request that the installation company describe the new features, energy efficiency, brand, estimated installation time, and model. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.
A reputable HVAC company will stand behind its repair work 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 most 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.
You should have your HVAC system inspected approximately twice a year. At the time of the inspection, your technician will tell you if any services are required. You should also call a technician if you start noticing issues such as strange noises, unusual smells, or leaks. If your home has ductwork, you should have it inspected every few years.
Generally, it's smart 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 likely 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 changes in the temperature — only increase or decrease it a few degrees at a time. If you're able to, try switching to a smart thermostat.
Generally, HVAC installation or replacement takes one to three days for the entire system. Installing or replacing an air conditioning unit or a furnace takes anywhere from about half a day up to two days. The exact amount of time will vary depending on factors like how large your home is, how easily accessible different sections are, and whether your technician runs into any problems.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Hornell, you'll probably be fine with a unit on the lower end of this range. For homes over 1,000 square feet, central air will 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). In Hornell, you might need a higher-capacity furnace.
Usually, HVAC financing is provided by a third-party lender. If your HVAC company doesn't have financing options, you might consider taking out a loan on your own. Be sure to talk to your HVAC company and a financial advisor to learn what options are available and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
