An HVAC system that's broken or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:
If you see any of these HVAC issues, you should have a technician inspect your system. A local professional can identify problems and determine whether repairing or getting a new HVAC unit is the best solution.
The price of HVAC installation or maintenance varies depending on the kind of unit you have. Common varieties of HVAC units include the following:
The price of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complex and can require different kinds of maintenance. The prices of some common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $2,006-$5,115 | |
| Hybrid Split | $4,066-$7,490 | |
| Heat Pump | $3,148-$32,077 | |
| Packaged Heating and Air | $263-$439 |
Repairing or replacing your HVAC system when needed is important, but can be expensive. Fortunately, there are actions you can take to minimize wear and tear over time on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $66-$176 | |
| Condensor Cleaning | $1,317-$3,951 | |
| Thermostat Repair | $88-$220 | |
| Ductwork Cleaning | $421-$1,054 |
Knowing what makes a trustworthy HVAC company is vital for an easy installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Get quotes from three or more HVAC contractors. Describe your issues and ask if specialists can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.
When picking an HVAC company, choose one with technicians that have the right training, licenses, and experience. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required 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 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.
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 confirm that your contractor meets all the requirements. You can also verify an Illinois business license on the Secretary of State's website. You should also look at reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a company with glowing reviews and reports of fantastic customer experiences.
Make sure you understand the details of any project before starting. For HVAC repairs, have your provider list which parts require replacement and why. Get confirmation that your technician will clean and test the entire system after the repair to ensure that everything works. When replacing your HVAC system, ask your installation company to provide details on the new brand, model, energy efficiency, features, and estimated installation time. 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.
A reputable HVAC company will back its repair work and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare warranty terms between contractors and choose the provider that offers the greatest protection at a reasonable price.
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 agree to 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 inform you what services are needed. You should also call a technician if you start noticing issues such as leaks, unusual smells, or strange noises. If your home has ductwork, you should have it inspected every few years.
Usually, it's a good idea to have your HVAC system inspected 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 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 possible, and avoid making drastic changes — adjust it only a few degrees at a time. You might also consider a smart thermostat.
Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing a furnace or air conditioning unit may take anywhere from a few hours up to two days. The exact amount of time will be based on things 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 should look for around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air will 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).
Your HVAC company might provide financing options via a third-party lender, or you might choose to obtain a loan on your own. 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 several ways you can make your HVAC system more energy-efficient:
