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:
A faulty or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Watch out for these common indicators that your HVAC needs service:
Schedule an inspection if you notice any of these issues. A local technician can assess your system, identify 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 types include the following:
The amount you spend on HVAC maintenance also depends on the kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The cost of some common repairs is as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,788-$4,558 | |
| Hybrid Split | $3,623-$6,674 | |
| Heat Pump | $2,805-$28,583 | |
| Packaged Heating and Air | $235-$391 |
Fixing your HVAC by repairing or replacing parts 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 | $59-$156 | |
| Condensor Cleaning | $1,174-$3,521 | |
| Thermostat Repair | $78-$196 | |
| Ductwork Cleaning | $376-$939 |
Finding the right HVAC company is vital for an easy installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning 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 provider, choose one with technicians that have the proper training, licenses, and experience. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians 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 on a state-by-state basis.
There is no state-level HVAC licensing in New York. 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. Also look at a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with great feedback and stories of satisfied customers.
It’s important to understand what the work process will look like. For HVAC repairs, the company should list the particular parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to guarantee everything is working correctly. For replacement, ask your contractor to explain the new HVAC system brand, features, model, energy efficiency, and estimated installation time. Before work begins, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.
Reliable HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers the best protection for the fairest price.
Always get HVAC quotes in writing before work begins. A thorough quote covers costs for both labor and materials. Confirm that you understand all terms before signing the contract.
You should have your HVAC system inspected twice yearly. After completing their inspection, your technician will tell you if any services are needed. You should also have your system inspected if you start noticing issues such as leaks, unusual smells, or strange noises. If your system has ductwork, it should be inspected every few years.
Normally, it's a good idea to schedule inspections in the spring and fall, as these times tend to be less busy. This also helps make sure your system is prepared for the summer and winter, when it probably sees the most use.
You can save energy during the winter by reducing the amount of work your HVAC system needs to do to heat your home. Keep your thermostat as low as is comfortable and don't make drastic temperature changes — only increase or decrease it a few degrees at a time. If possible, try switching to 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 takes anywhere from about half a day up to two days. The exact amount of time will be based on things like the size of your house, how easily accessible different sections are, and whether your technician runs into any problems.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Lewiston, you'll probably be fine with a unit that's on the lower end of this range. For a house over 1,000 square feet, central air will generally be more effective than window units for cooling.
For a 2,000-square-foot home, you should also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).
Your HVAC company might provide financing options via a third-party lender, or you might choose to obtain a loan on your own. It's smart to discuss payment options with your HVAC company and a financial advisor 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:
