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 broken or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Watch for these signs your system needs service:
If you see any of these HVAC issues, you should have a technician inspect your system. A local professional can identify problems and decide whether fixing or replacing your HVAC unit is the correct solution.
The price of HVAC installation or maintenance changes depending on the kind of unit you have. Common varieties of HVAC units include the following:
HVAC maintenance costs vary based on the specific services needed. HVAC systems can be complicated and potentially require several different services. Fees for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,842-$4,696 | |
| Hybrid Split | $3,732-$6,876 | |
| Heat Pump | $2,890-$29,447 | |
| Packaged Heating and Air | $242-$403 |
HVAC upkeep is important, but can be pricey. Fortunately, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $60-$161 | |
| Condensor Cleaning | $1,209-$3,628 | |
| Thermostat Repair | $81-$202 | |
| Ductwork Cleaning | $387-$967 |
Knowing what to look for in an HVAC company is crucial for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and ensure your system provides reliable air conditioning and heating for your home.
Contact at least three HVAC companies for quotes. Describe your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand upfront payment.
Look for an HVAC company that employs skilled technicians with 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 any individual who helps "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.
In New Jersey, HVAC contractors are required to be licensed by the Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors. Contractors must be bonded and must participate in continuing education, and individuals who operate an HVAC business must have general liability insurance. 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 glowing feedback and stories of satisfied customers.
Always make sure you understand the details of your project. For HVAC repairs, your provider should detail which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are completed to ensure that it’s working properly. When replacing your HVAC, ask the provider to explain the new energy efficiency, estimated installation time, model, features, and brand. Before signing paperwork, make sure you understand how your provider will determine the right system size for your home and what the price will be.
A reputable HVAC company will back its repair work and equipment 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 company that provides the greatest protection at a reasonable price.
Always get quotes for HVAC service in writing before work begins. An itemized quote should cover both materials and labor. Make sure you review all terms before signing a contract.
Normally, your HVAC system should be inspected twice a year. After an inspection, your HVAC technician will tell you what, if any, services are needed. You should also have an inspection if you notice any new issues, like strange noises, unusual smells, or leaks. If your home has ductwork, it should be serviced every few years.
The best times to have your HVAC system inspected are the spring and fall. Technicians tend to be less busy during these times, so it will be easier to get an appointment. This also ensures that your system is ready for the summer and winter, when it typically gets the most use.
You can save energy throughout the year by reducing the amount of work it takes for your HVAC system to maintain the temperature of your home. During all seasons, keep your thermostat as close to the outside temperature as possible, and avoid making drastic changes — adjust it only a few degrees at once. You may also consider 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 may take anywhere from a few hours up to two days. The exact amount of time will vary depending on factors like the size of your house, how easily accessible different areas are, and whether your technician runs into any problems.
For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will usually 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 may choose to obtain your own loan. It's a good idea 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:
