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 malfunctioning or past its lifespan likely needs professional attention for maintenance or replacement. Watch for these indicators that your system needs service:
These HVAC red flags indicate that you should have your system evaluated. A local provider can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.
What you pay for HVAC installation or maintenance varies based on your system type. Common HVAC unit styles include the following:
HVAC maintenance costs vary depending on the particular service needed. HVAC systems are complicated and may require different maintenance services. Fees for common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,975-$5,035 | |
| Hybrid Split | $4,002-$7,372 | |
| Heat Pump | $3,099-$31,573 | |
| Packaged Heating and Air | $259-$432 |
HVAC system repairs and replacements are important, but can be pricey. Luckily, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $65-$173 | |
| Condensor Cleaning | $1,296-$3,889 | |
| Thermostat Repair | $86-$216 | |
| Ductwork Cleaning | $415-$1,037 |
Knowing the indicators of a reliable 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.
Get quotes from three or more HVAC contractors. Describe your issues and ask if technicians can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.
Choose an HVAC company with skilled technicians who have appropriate licensing and experience. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals must pass an exam (the type of exam depends on the 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, 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. Also check a company's reviews and complaints on sites such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with glowing feedback and good customer testimonials.
Make sure you know the details of your project before starting. When getting HVAC repairs, have your provider specify which parts require replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. When getting a replacement, ask the contractor to explain the new HVAC system brand, features, energy efficiency, model, and estimated installation time. Before signing a contract, you should understand how your provider will size the system appropriately for your home and the price you'll pay.
Trustworthy HVAC companies provide warranties for their services. Broader coverage is better, so make sure to review warranties between providers. Choose the one that gives you the most coverage at a reasonable cost.
Get a written estimate before HVAC work begins. A full 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 approximately twice a year. Following an inspection, your technician will inform you if any services are needed. You should also call a technician if you start noticing issues such as strange noises, unusual smells, or leaks. If your home has ductwork, it should be inspected every few years.
Generally, you should have your HVAC system inspected 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 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 you can and avoid making drastic temperature changes — increase or decrease it a few degrees at a time. If possible, try switching to a smart thermostat.
It takes roughly one to three days to have an HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this might take anywhere from a few hours up to two days. This timeline can be determined by the size of your house, how easily accessible your system is, and any new issues your technician uncovers.
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 purchase an air conditioning unit with around 2.5 to 5 tons of capacity. In Colonie, a unit on the lower end of this range may be sufficient. Usually, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company might provide financing options via a third-party lender, or you might choose to obtain your own loan. 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 several ways you can make your HVAC system more energy-efficient:
