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 having issues or getting old, it likely needs repairs or replacement from an HVAC company. Watch for these indicators your system needs service:
If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.
The price of HVAC installation or maintenance varies depending on the type of unit you have. Common kinds of HVAC units 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 can require different kinds of maintenance. The prices of some common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,843-$4,698 | |
| Hybrid Split | $3,734-$6,880 | |
| Heat Pump | $2,891-$29,462 | |
| Packaged Heating and Air | $242-$403 |
It's important to repair or replace your HVAC system when it's broken, but it can also be expensive. Fortunately, there are steps you can take to reduce wear and tear on your HVAC.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $60-$161 | |
| Condensor Cleaning | $1,210-$3,629 | |
| Thermostat Repair | $81-$202 | |
| Ductwork Cleaning | $387-$968 |
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 in your home.
Request estimates from three or more HVAC companies. Describe your issues and ask if specialists can inspect your system in person. Review each contractor'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 set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals must pass an exam (the specific exam depends on what 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 by the state.
There are no state-level licensing requirements for contractors in Illinois. However, there may be local regulations, so make sure to check with your municipal government to verify that your contractor meets all the requirements. You can also verify an Illinois business license on the Secretary of State's website. Reviewing feedback on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can assist your decision as well. Choose a provider with great reviews and reports of positive customer experiences.
It’s important to understand what the work process is going to look like. For HVAC repairs, the company should explain the specific parts that need replacement and why. Get confirmation that your technician will clean and test your system afterward to ensure proper functioning. When replacing your HVAC, ask your contractor to provide details on the new brand, model, features, estimated installation time, and energy efficiency. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.
Trustworthy HVAC companies back their work with warranties. Look at warranties from different companies, keeping in mind that broader coverage is better. Look for the company that provides the most coverage for a fair price.
Get written quotes before starting HVAC work. The quote should outline costs for both labor and materials. Review all terms carefully before signing.
You should have your HVAC system inspected approximately twice annually. After the inspection, your technician will inform you what services are required. 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.
Usually, you should 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 typically sees the most use.
You can save energy throughout the year by reducing the amount of power your HVAC system uses to maintain the temperature of your home. During all seasons, keep your thermostat as close to the outside temperature as is comfortable, and avoid making drastic changes — adjust it only a few degrees at once. You could also consider installing a smart thermostat.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air will generally be more effective than window units for cooling.
For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Herrin, you might be able to make do with a lower-capacity furnace.
Your HVAC company may have financing options through a third-party lender, or you might be able 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:
