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 not working properly or old likely needs professional attention for maintenance or replacement. Watch for these signs that your system needs service:
If you see any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and let you know whether whether repairing or getting a new HVAC unit is the correct solution.
What you spend on HVAC installation or maintenance depends on your system type. Common HVAC unit styles include the following:
HVAC maintenance costs differ based on the specific services needed. HVAC systems can be complicated and potentially require several different services. Costs for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,932-$4,924 | |
| Hybrid Split | $3,914-$7,211 | |
| Heat Pump | $3,031-$30,881 | |
| Packaged Heating and Air | $254-$423 |
It’s important to take care of HVAC repairs and replacements when they are required, though they can be expensive. The good news is that homeowners have ways to minimize progressive deterioration and reduce the frequency of breakdowns.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $63-$169 | |
| Condensor Cleaning | $1,268-$3,804 | |
| Thermostat Repair | $85-$211 | |
| Ductwork Cleaning | $406-$1,014 |
It's important to know what makes a good HVAC company. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can keep your system running efficiently, providing you with effective air conditioning and heating in your home.
Get quotes from at least three HVAC companies. Explain your issues and ask if specialists can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid contractors that pressure you or demand payment before work.
When selecting an HVAC provider, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory for all contractors 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.
Illinois doesn't have state-level contractor licensing requirements. However, there may be local regulations, so make 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. You should also check reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a company with glowing reviews and testimonials about great customer experiences.
Make sure you understand the details of any project before starting. For HVAC repairs, have your provider specify which parts need replacement and why. Get confirmation that your technician will clean and test the system after the repair to ensure that everything works. When replacing your HVAC system, ask the installation company to provide details on the new estimated installation time, brand, energy efficiency, features, and model. Before work begins, 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.
Trustworthy HVAC companies stand behind their work with warranties. Compare warranties from different companies, remembering that broader coverage is better. Look for the company that offers the most coverage for a fair price.
Always get quotes for HVAC service in writing before work begins. An itemized quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.
You should have your HVAC system inspected about twice annually. After the inspection, your technician will tell you what services are required. You should also have your system inspected if you notice new issues such as strange noises, leaks, or unusual smells. If your home has ductwork, you should have it inspected every few years.
Normally, it's a good idea 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 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 possible, and avoid making drastic changes — adjust it only a few degrees at a time. You might also consider a smart thermostat.
It takes roughly one to three days to have your HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this can take between half a day and two days. This timeline can be influenced by the size of your home, how easily accessible your system is, and any new issues your technician uncovers.
For a 2,000-square-foot home, you'll want 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 an air conditioning unit with around 2.5 to 5 tons of capacity. 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 provided by a third-party lender. If your HVAC company doesn't offer financing, you might consider taking out a loan on your own. Be sure to speak with your HVAC company and a financial advisor to find out what options are available and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
