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 old likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:
Book an inspection if you notice any of these problems. A local technician can evaluate your system, detect problems, and figure out whether you need to fix or replace your HVAC.
HVAC installation or maintenance prices change depending on your system. Common HVAC unit varieties include the following:
HVAC maintenance prices vary depending on the particular service needed. HVAC systems are complex and may require different kinds of maintenance. Prices for some common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,924-$4,906 | |
| Hybrid Split | $3,899-$7,184 | |
| Heat Pump | $3,019-$30,766 | |
| Packaged Heating and Air | $253-$421 |
Repairing or replacing your HVAC system when needed is important, but can be expensive. Luckily, there are steps you can take to reduce gradual wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $63-$168 | |
| Condensor Cleaning | $1,263-$3,790 | |
| Thermostat Repair | $84-$211 | |
| Ductwork Cleaning | $404-$1,011 |
Finding the right HVAC company is key for a smooth installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Request estimates from three or more HVAC companies. Describe your issues and ask if technicians can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.
It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific 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.
HVAC contractors in North Carolina must be licensed through the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. Not all individuals who work for a licensed firm need to be individually licensed; however, all work must be supervised by a licensed contractor. A contractor may hold multiple different licenses for different types of jobs. Reviewing feedback on Google Reviews, the Better Business Bureau (BBB), Yelp, and similar sites can help your decision as well. Choose a company with great reviews and stories of positive customer experiences.
Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to explain which parts need replacement and explain why. Confirm that your technician will clean and test your system at the end of the job to guarantee proper operation. When replacing your HVAC system, ask the contractor to provide details on the new estimated installation time, model, features, energy efficiency, and brand. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.
Reliable HVAC companies offer warranties on service and equipment installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that offers the most comprehensive protection for a fair price.
Always get HVAC estimates in writing before work begins. A detailed quote will cover costs for both labor and materials. Confirm that you understand all terms before signing the contract.
Typically, you should have your HVAC system inspected twice a year. After an inspection, your technician will tell you what, if any, services are required. You should also have your system inspected and serviced if you start to notice any issues, like strange noises, unusual smells, or leaks. If you have ductwork in your home, it should be serviced every few years.
The best times to have your HVAC system inspected are during the spring and fall. Technicians are often less busy during these times, making it 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 during the summer by making it easier for your HVAC system to keep your home cool. Set your thermostat as close to the outside temperature as is comfortable, and try to avoid making drastic changes in temperature all at once. Keep your roof in good shape and seal any leaks around your windows and doors to help keep cool air in. Similarly, ensure that your attic is well ventilated to avoid trapping excess heat in your home.
Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing an air conditioning unit or a furnace can take as little as half a day or as much as two days. The exact amount of time will depend on things like the size of your home, how easily accessible different areas are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you should look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Apex, you may be able to make do with a lower-capacity furnace.
For a 2,000-square-foot home, you'll also want an air conditioning unit with around 2.5 to 5 tons of capacity. In Apex, you'll likely look for something on the higher end of this range. Generally, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company may have financing options via 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're choosing the best option for you.
There are a number of ways you can make your HVAC system more energy-efficient:
