If your home's HVAC system is malfunctioning or suffering from a lot of wear and tear, you might need an HVAC contractor for maintenance or replacement. Watch for these common signs that your system requires expert attention:
If you notice any of these HVAC red flags, your system evaluated. A local technician can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.
HVAC installation or maintenance costs vary depending on your system. Common HVAC unit varieties include the following:
The amount you spend on HVAC maintenance also varies depending on what kind of work you're having done. HVAC systems are complicated and may require different kinds of maintenance. The cost of some common repairs is as follows:

It’s important to complete repairs or full-system HVAC replacements as needed, 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 crucial for an easy installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.
Request estimates from at least three HVAC providers. Explain your issues and ask if technicians can inspect your system in person. Compare each provider's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid companies that pressure you or demand payment before work.
It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific exam depends on the 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 on a state-by-state basis.
The state of Missouri doesn't have state-level HVAC contractor licensing requirements; however, most municipalities have local requirements. It's always a good idea to check with your local government to understand requirements for licenses such as HVAC Contractor or HVAC Journeyman Contractor. You can also check that a company holds a valid business license. You should also check a provider's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Look for a a company with positive reviews and a history of good customer service.
Always make sure you know what a company’s process looks like. When HVAC repairs are needed, ask your provider to explain which parts require replacement and explain why. Confirm that your technician will clean and test the system after finishing the work to verify proper operation. When replacing your HVAC, ask the provider to explain the new features, estimated installation time, energy efficiency, model, and brand. Before signing paperwork, make sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.
Reputable HVAC companies stand behind their services with warranties. Compare warranties from different companies, while remembering that broader coverage is better. Look for the provider that offers the most coverage for a fair price.
Always get HVAC quotes in writing before work begins. A detailed quote will cover costs for both labor and materials. Make sure that you understand all terms before signing the contract.
You should have your HVAC system inspected about twice annually. Following an 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, unusual smells, or leaks. If your system has ductwork, it should be inspected every few years.
Usually, it's smart 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 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 possible, and avoid making drastic changes — adjust it only a few degrees at once. You might also consider installing a smart thermostat.
It takes between one and three days to have your HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this can take between half a day and two days. This timeline will be influenced by the size of your house, how easily accessible your system is, and any issues your technician runs into.
For a 2,000-square-foot home, try to purchase 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 look for an air conditioning unit with between 2.5 and 5 tons of capacity. Usually, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
There are several ways you can make your HVAC system more energy-efficient:
