If your HVAC system is having issues or getting old, it likely needs servicing or replacement from an HVAC company. Look for these signs your system needs service:
If you're experiencing any of these HVAC issues, you should have a technician inspect your system. A local professional can detect problems and decide whether fixing or replacing your HVAC unit is the correct solution.
The price of HVAC installation or maintenance changes depending on the kind of unit you have. Common kinds of HVAC units include the following:
HVAC costs differ based on the work needed. HVAC systems are complicated and may need several types of maintenance. Costs for common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,965-$5,010 | |
| Hybrid Split | $3,983-$7,337 | |
| Heat Pump | $3,084-$31,422 | |

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Thankfully, there are some steps you can take to slow the wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $65-$172 | |

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 consistent heating and air conditioning year-round.
Contact at least three HVAC companies for quotes. Explain the issues and have specialists visit to inspect your system if possible. Compare the companies' explanations, solutions, estimated costs, warranties, and timeframes. Avoid contractors that pressure you or demand payment upfront.
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, a contractor 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.
Indiana doesn't have any state-level licensing requirements for HVAC contractors; however, most cities and municipalities have their own requirements. Make sure that you check with your local government and verify the business license of any company you hire. You should also look at reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Choose a company with glowing reviews and testimonials about fantastic customer experiences.
Always make sure you understand what a company’s process is like. When getting HVAC repairs, ask your provider to explain which parts need replacement and why. Confirm that your technician will clean and test your system at the end of the job to guarantee proper operation. When replacing your HVAC, ask the provider to explain the new features, model, estimated installation time, energy efficiency, and brand. Before work starts, be sure you understand how your provider will determine the right system size for your home and what the price will be.
Reliable HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers the best protection within your budget.
Always get estimates for HVAC service in writing before work begins. A comprehensive 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 a year. After the inspection, your technician will inform you if any services are required. You should also call a technician if you start noticing issues such as strange noises, unusual smells, or leaks. If your home has ductwork, it should be inspected every few years.
Generally, it's a good idea to schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared for the summer and winter, when it probably sees the most use.
You can save energy throughout the year by making it easier for your HVAC system to maintain the temperature of your home. Always keep your thermostat as close to the outside temperature as you can, and avoid making drastic changes — adjust it only a few degrees at once. You could also consider a smart thermostat.
Generally, whole-system HVAC installation or replacement takes one to three days. 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 how large your home is, how easily accessible different parts of the system 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).
Normally, HVAC financing is offered through a third-party lender. If your HVAC company doesn't have financing options, you could consider taking out a loan on your own. Be sure to talk to a financial advisor and your HVAC company to find out what options are available to you and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
