Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting old, it likely needs repairs or replacement from an HVAC company. Look for these signs your system needs service:

  • Refrigerant leaks
  • Poor air circulation or uneven heating/cooling
  • Cracking, rust, or corrosion
  • Thermostat malfunctions or temperature control issues
  • Unusually high energy bills
  • Strange noises when the system turns on
  • Frequent breakdowns and need for repairs
  • An HVAC system that's over 15 years old

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can identify problems and let you know whether repair or full HVAC replacement is the best course of action.

Cost of HVAC Installation and Maintenance in Cape Girardeau

The price of HVAC installation or maintenance varies depending on the kind of unit you have. Common kinds of HVAC units include the following:

  • Split or mini-split: If your home lacks the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of interior units that regulate the temperature in individual rooms, and that are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the benefit of having the capability to use either gas or electricity for power.
  • Heat pump: Heat pumps transfer hot and cool air between your home and outside. They don't make their own heat or AC, so they work best in mild climates.
  • Packaged heating and air: Packaged HVAC systems are a practical choice for smaller homes. These systems have a single combined AC and heating, typically located in an attic or basement. They're space-saving, cost-effective, and easy to maintain.

HVAC maintenance costs vary depending on the particular service needed. HVAC systems are complex and might require different maintenance services. Fees for common services are as follows:

HVAC Unit TypeCost
Split$1,891-$4,821
Hybrid Split$3,832-$7,060
Heat Pump$2,967-$30,233
Packaged Heating and Air$248-$414

Ways to Save Money on HVAC Costs

HVAC upkeep is important, but can be expensive. Thankfully, homeowners can take steps to reduce wear and tear on their HVAC and lower future maintenance needs.

  • Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow smoothly through your system. Also try to keep debris away from the outside areas of your HVAC system as much as possible.
  • Monitor for potential problems. Keep an eye on your system for issues, for example by consistently checking your thermostat and energy bills. This enables you to address problems before they get too expensive.
  • Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help lower the work required from your home’s HVAC system.
  • Keep your system clean. Keeping your condenser fan blades, grills, indoor evaporator coil, and ductwork clean helps your system run and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system when it starts to look dirty.
ServiceCost
Filter Replacement$62-$166
Condensor Cleaning$1,241-$3,724
Thermostat Repair$83-$207
Ductwork Cleaning$397-$993

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is crucial for a successful installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.

Compare Multiple Bids

Get quotes from three or more HVAC providers. Describe your issues and ask if technicians can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid providers that pressure you or demand payment before work.

Check Credentials

When selecting an HVAC company, choose one with technicians that have the right training, licenses, and experience. In all states, HVAC contractors must 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." An individual 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 by the state.

Missouri doesn't have state-level licensing requirements for HVAC contractors; however, most municipalities have local requirements. It's always a good idea to check with your local government to understand requirements for licenses like HVAC Contractor or HVAC Journeyman Contractor. You can also confirm that a company holds a valid business license. You should also look at a company's reviews and complaints on sites such as Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with great feedback and good customer testimonials.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should list the particular parts that need replacement and why. Get confirmation that your technician will clean and test your system afterward to guarantee everything is working correctly. When replacing your HVAC, ask your contractor to provide details on the new features, model, energy efficiency, brand, and estimated installation time. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

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 the fine print between contractors and choose the provider that offers the greatest protection at a reasonable price.

Get Quote in Writing

Get a written quote before HVAC work begins. A full quote includes both materials and labor costs. Make sure you understand and agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Cape Girardeau, MO

You should have your HVAC system inspected approximately twice a year. Following an inspection, your technician will tell you what services are needed. You should also schedule an inspection if you start noticing issues such as unusual smells, leaks, or strange noises. If your home has ductwork, you should have it inspected every few years.

Usually, it's smart to schedule inspections in the spring and fall, as these times tend to be less busy. 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 reducing the amount of work it takes for your HVAC system to maintain your home's temperature. 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 purchasing 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 can take as little as half a day or as much as two days. The exact amount of time will vary depending on things like the size of your home, how easily accessible different areas are, and whether your technician finds any problems.

Normally, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer financing, you could consider taking out a loan on your own. Be sure to talk to your HVAC company and a financial advisor to learn what options are available and appropriate for your situation.

There are a number of ways you can make your HVAC system more energy-efficient:

  • Keep ductwork clean, and change or clean your air filters regularly.
  • Schedule regular inspections to take care of issues as they arise.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you aren't able to purchase one, try to keep your inside temperature as close to the outside temperature as is comfortable.
  • When you need to replace part of your system, see if there are Energy Star-certified or other environmentally friendly options.
