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 faulty or getting old, it likely needs repairs or replacement from an HVAC company. Watch for these signs your system needs service:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can identify problems and recommend whether repair or full HVAC replacement is required.
The price of HVAC installation or maintenance varies depending on the type of unit you have. Common types of HVAC units include the following:
HVAC maintenance prices differ depending on the particular service needed. HVAC systems are complex and might require different maintenance services. Costs for common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,893-$4,827 | |
| Hybrid Split | $3,836-$7,068 | |
| Heat Pump | $2,971-$30,269 | |
| Packaged Heating and Air | $249-$414 |
Repairing or replacing your HVAC system when needed is important, but can be expensive. Luckily, there are actions you can take to slow the wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $62-$166 | |
| Condensor Cleaning | $1,243-$3,729 | |
| Thermostat Repair | $83-$207 | |
| Ductwork Cleaning | $398-$994 |
Knowing the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can maintain your HVAC system properly, providing you with effective air conditioning and heating for your home.
Get quotes from three or more HVAC companies. 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 provider, choose one with technicians that have the appropriate training, licenses, and experience. In all states, HVAC contractors need to 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 what kind 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 Alabama, HVAC contractors must be licensed through the Board of Heating, Air Conditioning and Refrigeration Contractors. Contractors must hold a surety bond and must complete a set number of continuing education hours each year. You should also check a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with great feedback and stories of satisfied customers.
Make sure you understand the details of your project before it begins. For HVAC repairs, have your provider detail which parts require replacement and why. Confirm that your technician will clean and test the system after the repair to ensure that everything works. When getting a replacement, ask your contractor to explain the new HVAC system model, estimated installation time, features, brand, and energy efficiency. Before work begins, 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 compare warranties between companies. Choose the one that offers the best coverage at a fair cost.
Always get estimates for HVAC service in writing before work begins. An itemized quote should cover both labor and materials. Make sure you understand all terms before signing a contract.
You should have your HVAC system inspected about twice annually. At the time of the inspection, your technician will tell you if any services are required. You should also have your system inspected if you notice new issues such as strange noises, unusual smells, or leaks. If your system has ductwork, it should be inspected every few years.
Normally, 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 reducing the amount of power your HVAC system uses 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 well-maintained 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.
It takes between one and three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this might take between half a day and two days. This timeline will be influenced by the size of your house, how easily accessible your system is, and any new issues your technician discovers.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. In Clay, you'll probably want to explore units on the higher end of this range. If your home is larger than 1,000 square feet, central air is likely to be more effective for cooling than window units.
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). In Clay, you might be able to make do with a lower-capacity furnace.
Typically, HVAC financing is through a third-party lender. If your HVAC company doesn't offer financing, you could consider taking out your own loan. Be sure to talk to your HVAC company and a financial advisor to find out what options are available to you and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
