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:
An HVAC system that's broken or outdated likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:
Book an inspection if you notice any of these problems. A local technician can assess your system, detect problems, and determine whether you need to fix or replace your HVAC.
Your HVAC installation or maintenance cost varies depending on the type of unit. Common HVAC unit varieties include the following:
HVAC expenses vary based on the services needed. HVAC systems are complicated and may need a number of types of maintenance. Prices for common jobs 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. Fortunately, there are steps you can take to reduce wear and tear on your HVAC.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $64-$170 | |
| Condensor Cleaning | $1,278-$3,833 | |
| Thermostat Repair | $85-$213 | |
| Ductwork Cleaning | $409-$1,022 |
Knowing the right things to look for in an HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.
Request estimates from three or more HVAC providers. Describe your issues and ask if specialists can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.
Look for an HVAC company that employs qualified technicians who have the necessary training and licenses. 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." Contractors 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, 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. Reviewing feedback on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can help your decision as well. Choose a company with great reviews and reports of positive customer experiences.
Always make sure you know the details of your project. When HVAC repairs are required, your provider should detail which parts need replacement and why. Confirm that your technician will clean and test the system after repairs are completed to verify that it’s working properly. When replacing your HVAC, ask the provider to explain the new estimated installation time, model, features, brand, and energy efficiency. Before signing a contract, make sure you understand how your provider will determine the right system size for your home and what the price will be.
Reliable HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that provides the most comprehensive protection for the fairest price.
Get written quotes before starting HVAC work. The quote should cover costs for both labor and materials. Read all terms carefully before signing.
You should have your HVAC system inspected about twice yearly. Following an inspection, your technician will tell you if any services are required. You should also schedule an inspection if you notice new issues such as unusual smells, leaks, or strange noises. If your system has ductwork, you should have it inspected every few years.
Generally, it's a good idea to have your HVAC system inspected 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 you can and avoid making drastic temperature changes — only increase or decrease it a few degrees at a time. If you can, try switching to a smart thermostat.
It takes roughly one to three days to have your HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this might take between half a day and two days. This timeline will be determined by the size of your home, the accessibility of your system, and any issues your technician discovers.
For a 2,000-square-foot home, you'll want 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 look for an air conditioning unit with between 2.5 and 5 tons of capacity. In Farmington, a unit on the lower end of this range may be sufficient. Typically, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company might provide financing options through a third-party lender, or you might be able to obtain a loan on your own. It's a good idea to discuss payment options with a financial advisor and your HVAC company to make sure that you find the best option for you.
