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 repairs or replacement. Watch for these signals that your system needs service:
Schedule an inspection if you notice any of these problems. A local technician can assess your system, detect problems, and decide whether you need to fix or replace your HVAC.
HVAC installation or maintenance costs vary depending on your system. Common HVAC unit varieties include the following:
The amount you spend on HVAC maintenance also varies depending on the kind of work you're having done. HVAC systems are complicated and may require different kinds of maintenance. The cost of some common repairs is as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,737-$4,429 | |
| Hybrid Split | $3,520-$6,486 | |
| Heat Pump | $2,726-$27,776 | |
| Packaged Heating and Air | $228-$380 |
It’s important to make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $57-$152 | |
| Condensor Cleaning | $1,141-$3,422 | |
| Thermostat Repair | $76-$190 | |
| Ductwork Cleaning | $365-$912 |
It's important to know what makes a good HVAC company. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling for your home.
Contact at least three HVAC providers for quotes. Explain the issues and have technicians visit to inspect your system if possible. Compare the companies' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.
Choose an HVAC company with highly trained technicians who have appropriate licensing and experience. HVAC contractors in all states have federal requirements set by 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 intend 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.
In Oklahoma, HVAC contractors are required to be licensed by the Oklahoma Construction Industries Board. For HVAC work, a contractor may have an HVAC/R limited license (which lets them work only on small jobs) or an HVAC/R unlimited license (which allows them to work on all jobs). Individuals must have four years of experience and must pass an exam in order to become fully licensed contractors. You should also check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Choose a provider with positive reviews and a history of good customer service.
Always make sure you understand the details of any project. For HVAC repairs, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test the full system after repairs are completed to verify that it’s working properly. When replacing your HVAC system, ask your installation company to provide details on the new estimated installation time, features, brand, energy efficiency, and model. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.
Reliable HVAC companies provide warranties for their work. 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 quotes for HVAC service in writing before committing to a provider. An itemized quote should cover both materials and labor. Make sure you review all terms before signing a contract.
You should have your HVAC system inspected about twice a year. Following an inspection, your technician will tell you if any services are needed. You should also have your system inspected if you notice new issues such as unusual smells, strange noises, or leaks. If your system has ductwork, you should have it inspected every few years.
Generally, it's best to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. 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 summer by reducing the amount of power your HVAC system uses to keep your home cool. Keep your thermostat temperature as close to the outside temperature as you can, and avoid making drastic changes in temperature all at once. Keep your roof well-maintained and seal any window or door leaks to avoid letting cool air escape. 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 may take anywhere from a few hours up to two days. The exact amount of time will be based on factors like the size of your home, 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 Lawton, 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 between 2.5 and 5 tons of capacity. In Lawton, you'll likely want a unit 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.
There are several ways you can make your HVAC system more energy-efficient:
