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 broken 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 these HVAC issues, we recommend having a technician inspect your system. A local professional can detect problems and decide whether fixing or replacing your HVAC unit is the best solution.
What you spend on HVAC installation or maintenance is determined by your system style. Common HVAC unit styles include the following:
The price of HVAC maintenance also varies depending on what kind of work being 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 | $1,973-$5,030 | |
| Hybrid Split | $3,998-$7,366 | |
| Heat Pump | $3,096-$31,544 | |
| Packaged Heating and Air | $259-$432 |
Essential HVAC maintenance is important, but can be pricey. Thankfully, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $65-$173 | |
| Condensor Cleaning | $1,295-$3,886 | |
| Thermostat Repair | $86-$216 | |
| Ductwork Cleaning | $414-$1,036 |
Knowing the right things to look for in an HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.
Contact at least three HVAC contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.
Choose an HVAC company with skilled technicians who have appropriate licensing and experience. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual 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 at the state level.
The state of Illinois doesn't have state-level licensing requirements for contractors. However, there may be local regulations. Be sure to check with your municipal government to verify that your contractor meets all of the requirements. You can verify an Illinois business license on the Secretary of State's website. Always check a company's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. You want to hire a provider with glowing reviews and stories of positive service experiences.
It’s important to understand what the work process is going to look like. For HVAC repairs, the company should explain the particular parts that need replacement and why. Confirm that your technician will clean and test your system afterward to guarantee everything is working correctly. For replacement, ask the contractor to explain the new HVAC system model, features, brand, estimated installation time, and energy efficiency. Before starting the project, 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 work. The broader the coverage, the better, so make sure to compare warranties between providers. Choose the one that gives you the most coverage at a fair cost.
Always get quotes for HVAC service in writing before committing to a provider. A detailed quote should cover both labor and materials. Make sure you review all terms before signing a contract.
You should have your HVAC system inspected approximately twice annually. After the inspection, your technician will inform you what services are needed. You should also schedule an inspection if you notice new issues such as strange noises, leaks, or unusual smells. If your system has ductwork, it should be inspected every few years.
Normally, you should have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it typically sees the most use.
You can save energy throughout the year by making it easier for your HVAC system to maintain your home's temperature. Always keep your thermostat as close to the outside temperature as you can, and try to adjust it only a few degrees at a time. You might also consider installing a smart thermostat.
Generally, whole-system HVAC installation or replacement takes between one and 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 factors like the size of your house, how easily accessible different sections are, and whether your technician finds any problems.
For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units).
For a 2,000-square-foot home, you'll also want to purchase an air conditioning unit with around 2.5 to 5 tons of capacity. In general, 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 through a third-party lender, or you may be able to obtain a loan on your own. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you're choosing the best option for you.
