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 past its lifespan likely needs professional attention for repairs or replacement. Watch for these indicators that your system needs service:
If you notice any of the above, have a local HVAC technician inspect your system. They can pinpoint problems and recommend whether repair or full HVAC replacement is required.
The cost of HVAC installation or maintenance will vary depending on the type of unit you have. Common kinds of HVAC units include the following:
HVAC maintenance prices vary based on the work needed. HVAC systems are complicated and may need multiple types of maintenance. Costs for common jobs are as follows:
HVAC Unit Type | Cost | |
---|---|---|
Split | $1,869-$4,765 | |
Hybrid Split | $3,787-$6,977 | |
Heat Pump | $2,932-$29,880 | |
Packaged Heating and Air | $245-$409 |
HVAC upkeep is important, but can be pricey. Thankfully, homeowners can take steps to reduce wear and tear on their HVAC and lower future maintenance needs.
Service | Cost | |
---|---|---|
Filter Replacement | $61-$164 | |
Condensor Cleaning | $1,227-$3,681 | |
Thermostat Repair | $82-$204 | |
Ductwork Cleaning | $393-$982 |
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 heating and cooling year-round.
Request estimates from three or more HVAC contractors. Describe your issues and ask if specialists can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.
When hiring an HVAC company, choose one with technicians that have the right training, licenses, and experience. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory 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.
In North Carolina, HVAC contractors must be licensed via the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. A licensed firm may employ individuals who aren't all individually licensed; however, all work must be supervised by a licensed contractor. A contractor may hold multiple different licenses for different kinds of jobs. You should also check reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with positive reviews and testimonials about great customer experiences.
It’s important to know what the work process will look like. For HVAC repairs, the company should detail the specific parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to guarantee everything is working correctly. When replacing your HVAC system, ask your contractor to provide details on the new features, energy efficiency, brand, estimated installation time, and model. 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.
Good 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 within your budget.
Always get estimates for HVAC service in writing before work begins. A comprehensive quote should cover both labor and materials. Make sure you review all terms before signing a contract.
You should have your HVAC system inspected twice a year. Following an inspection, your technician will inform you if any services are needed. You should also have your system inspected if you start noticing issues such as leaks, strange noises, or unusual smells. If your system has ductwork, it should be inspected every few years.
Generally, it's best to schedule inspections in the spring and fall, as these times tend to be less busy. This also helps get your system ready for the summer and winter, when it likely sees 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, make sure your attic is well ventilated to avoid trapping excess heat in your home.
Generally, whole-system HVAC installation or replacement takes one to three days. Installing or replacing a furnace or air conditioning unit can take as little as half a day or as much as two days. The exact amount of time will be based on things like how large your home is, how easily accessible different sections are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you'll want a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Durham, you may be able to make do with a furnace on the lower end of this range.
For a 2,000-square-foot home, you'll also want an air conditioning unit with between 2.5 and 5 tons of capacity. In Durham, 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.
Normally, HVAC financing is through a third-party lender. If your HVAC company doesn't offer these options, you might consider taking out your own loan. Be sure to talk to a financial advisor and your HVAC company to find out what options are available and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
