Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs attention from a professional who can make repairs or install a new unit. Keep an eye out for these common indicators that your HVAC needs service:

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

Schedule an inspection if you notice any of these issues. A local technician can evaluate your system, identify problems, and figure out whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Eureka

The price of HVAC installation or maintenance changes depending on the type of unit you have. Common types of HVAC units include the following:

  • Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have internal units in each room to control temperature. These indoor units all connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the benefit of being able to draw power from either electric or gas sources.
  • Heat pump: Heat pumps transfer warm and cool air between your home and the outside. These systems don't produce their own heat or AC, so they work better in moderate climates.
  • Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined heating and air conditioning unit, commonly located in a basement or attic. This unit is typically space-saving, energy-efficient, and straightforward to maintain.

HVAC maintenance prices vary based on the specific services needed. HVAC systems can be complicated and potentially require a number of services. Price ranges for typical jobs are as follows:

HVAC Unit TypeCost
Split$1,987-$5,064
Hybrid Split$4,025-$7,416
Heat Pump$3,117-$31,760
Packaged Heating and Air$261-$435

Ways to Save Money on HVAC Costs

It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Fortunately, there are some steps you can take to slow the wear and tear on your system.

  • Keep your system clean. Keeping your ductwork, condenser fan blades, grills, and indoor evaporator coil clean helps your HVAC system function properly and lowers the risk of mold. The National Air Duct Cleaners Association suggests cleaning your HVAC when you notice it starting to get dirty.
  • Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This allows you to address issues before they get out of hand.
  • Change filters regularly. Switching out or cleaning your air filters every 1–3 months helps air flow smoothly through your HVAC system. You should also try to prevent dirt and debris from building up around the outside areas of your system.
  • Change the position of your blinds seasonally. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the amount of work your HVAC system needs to do.
ServiceCost
Filter Replacement$65-$174
Condensor Cleaning$1,304-$3,912
Thermostat Repair$87-$217
Ductwork Cleaning$417-$1,043

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Partnering with an experienced, licensed contractor can offer you peace of mind and ensure your system provides reliable air conditioning and heating for your home.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Explain your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand upfront payment.

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. In all states, HVAC contractors 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 what kind of equipment they intend 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.

There are no state-level licensing requirements for HVAC technicians in Missouri; however, most municipalities have local requirements. It's in your best interest 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. Checking reviews on Yelp, the Better Business Bureau (BBB), Google Reviews, and similar sites can help your decision. Choose a company with great reviews and stories of positive customer experiences.

Understand Work Details

Make sure you know the details of any project before starting. For HVAC repairs, have your provider specify which parts need replacement and why. Confirm that your technician will clean and test the entire system after the repair to ensure that everything works. When replacing your HVAC, ask the provider to explain the new model, energy efficiency, features, brand, and estimated installation time. Before work starts, 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.

Compare Warranties

Trustworthy HVAC companies provide warranties for their work. The broader the coverage, the better, so make sure to review warranties between providers. Choose the one that provides the most comprehensive coverage at a fair cost.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Eureka, MO

Typically, you should have your HVAC system inspected twice a year. After that inspection, your technician will tell you what services are required. You should also call a technician if you notice any new issues, such as strange noises, unusual smells, or leaks. If your home has ductwork, it should be serviced every few years.

The best times to have your HVAC system inspected are the spring and fall. Technicians are often less busy during these times, making it easier to get an appointment. This also ensures that your system is ready for the summer and winter, when it typically gets the most use.

You can save energy throughout the year by making it easier for your HVAC system to maintain your home's temperature. Always keep your thermostat as close to the outside temperature as is comfortable, and try to adjust it only a few degrees at a time. You might also consider purchasing a smart thermostat.

Generally, whole-system HVAC installation or replacement takes one to three days. 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 factors like the size of your home, how easily accessible different areas are, and whether your technician finds any problems.

For a 2,000-square-foot home, you'll want 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 purchase an air conditioning unit with between 2.5 and 5 tons of capacity. Generally, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

Usually, 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 speak with your HVAC company and a financial advisor to determine what options are available to you 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 on a regular basis.
  • Have regular inspections to take care of problems as they come up.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • Install a smart thermostat. If you don't want to or can't buy one, try to keep the temperature indoors as close to the outside temperature as you can.
  • When you need to replace part of your system, see if there are Energy Star-certified or other environmentally friendly options.
