If your HVAC system is faulty or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Watch for these indicators your system needs service:
Schedule an inspection if you notice any of these issues. A local technician can inspect your system, identify problems, and determine whether you need to fix or replace your HVAC.
Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit varieties include the following:
HVAC costs differ based on the services needed. HVAC systems are complicated and may need multiple types of maintenance. Costs for common jobs are as follows:

Hybrid Split | $3,814-$7,026 | |
Heat Pump | $2,953-$30,089 | |

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 reduce gradual wear and tear and reduce the frequency of breakdowns.

Knowing what makes a trustworthy HVAC company is key 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.
Request estimates from three or more HVAC providers. Describe your issues and ask if technicians can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.
When selecting an HVAC provider, choose one with technicians that have the appropriate training, licenses, and experience. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians 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 by the state.
Missouri doesn't have state-level licensing requirements for HVAC contractors; however, most municipalities have local requirements. Be sure to check with your local government to understand requirements for licenses such as HVAC Contractor or HVAC Journeyman Contractor. You can also confirm that a company holds a valid business license. Checking reviews on Yelp, the Better Business Bureau (BBB), Google Reviews, and similar sites can assist your decision. Choose a provider with great reviews and stories of positive experiences from customers.
It’s important to know what the work process will 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 make sure everything is operating properly. When replacing your HVAC, have the contractor explain the new model, estimated installation time, features, 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 service and installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the most comprehensive protection for the fairest price.
Get written estimates before beginning HVAC work. The quote should include costs for both materials and labor. Review all terms carefully before signing.
You should have your HVAC system inspected about twice annually. At the time of the inspection, your technician will tell you if any services are needed. You should also have your system inspected if you start noticing issues such as leaks, unusual smells, or strange noises. If your system has ductwork, it should be inspected every few years.
Generally, it's best to 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 likely 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. During all seasons, keep your thermostat as close to the outside temperature as you can, and avoid making drastic changes — adjust it only a few degrees at a time. You could also consider installing a smart thermostat.
Generally, HVAC installation or replacement takes one to three days for the entire system. Installing or replacing a furnace or air conditioning unit takes anywhere from about half a day up to two days. The exact amount of time will depend on things like the size of your house, how easily accessible different areas are, and whether your technician discovers any problems.
Your HVAC company may offer financing options via a third-party lender, or you may choose to obtain a loan on your own. It's smart to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.
There are several ways you can make your HVAC system more energy-efficient:
