Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or outdated likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:

  • Strange noises when the system turns on
  • Frequent breakdowns and need for repairs
  • Thermostat malfunctions or temperature control issues
  • Cracking, corrosion, or rust
  • Higher than normal energy bills
  • Uneven heating/cooling or poor air circulation
  • Refrigerant leaks
  • 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 diagnose problems and let you know whether repair or full HVAC replacement is the better solution.

Cost of HVAC Installation and Maintenance in Maryville

What you pay for HVAC installation or maintenance depends on your system type. Common HVAC unit styles include the following:

  • Split or mini-split: If your home doesn’t have the ductwork for central air or heating, you likely have a split or mini-split system instead. Split HVAC systems have interior units in each room to control temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions much like a standard split system, but has the capacity to draw on either electricity or gas for power.
  • Heat pump: Heat pumps transfer hot and cool air between your home and the outdoors. They don't generate their own heat or AC, so they perform best in moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. These systems have a single combined AC and heating, normally located in an attic or basement. They're space-saving, cost-effective, and easy to maintain.

The amount you spend on HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complicated and might require different kinds of maintenance. The prices of some common jobs are as follows:

HVAC Unit Type Cost
Split $1,881-$4,796
Hybrid Split $3,812-$7,023
Heat Pump $2,951-$30,074
Packaged Heating and Air $247-$412

Ways to Save Money on HVAC Costs

Fixing your HVAC by repairing or replacing parts when needed is important, but can be expensive. Thankfully, there are steps you can take to minimize wear and tear over time on your system.

  • Keep your system clean. Keeping your condenser fan blades, indoor evaporator coil, ductwork, and grills clean helps your HVAC system function effectively and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when you notice things starting to get dirty.
  • Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow smoothly through your system. You should also try to keep debris away from the external sections of your HVAC system as much as possible.
  • 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.
  • Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This helps you address issues before they get out of hand.

Service Cost
Filter Replacement $62-$165
Condensor Cleaning $1,235-$3,705
Thermostat Repair $82-$206
Ductwork Cleaning $395-$988

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial for a successful project. Look for an experienced, licensed contractor that can give 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 companies 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

When hiring 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 mandatory for any individual who helps "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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.

The state of Illinois doesn't have state-level licensing requirements for contractors. However, there may be local regulations. Be sure to check with your municipal government to verify that your contractor meets all the requirements. You can verify an Illinois business license on the Secretary of State's website. You should also check a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with positive feedback and good customer testimonials.

Understand Work Details

Always make sure you understand what a company’s process looks 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 getting a replacement, ask the contractor to explain the new HVAC system energy efficiency, model, features, brand, and estimated installation time. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Reliable HVAC companies provide warranties for their services. Broader coverage is better, so make sure to review warranties between companies. Choose the one that offers the best coverage at a reasonable cost.

Get Quote in Writing

Always get HVAC quotes in writing before work begins. A detailed quote will cover costs for both labor and materials. Confirm that you agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Maryville, IL

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

The best times to have an HVAC inspection are during the spring and fall. Technicians tend to be less busy during these times, so it will be easier to get an appointment. This also ensures that your system is ready for the summer and winter, which is when it normally 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 try to adjust it only a few degrees at a time. You may also consider 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 vary depending on things 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 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 around 2.5 to 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.

Typically, HVAC financing is offered through a third-party lender. If your HVAC company doesn't have financing options, you may consider taking out your own loan. Be sure to talk to a financial advisor and your HVAC company to determine what options are available to you and appropriate for your situation.

There are several ways you can make your HVAC system more energy-efficient:

  • Keep your air ducts clean and change or clean your air filters on a regular basis.
  • Schedule regular inspections to take care of problems as they arise.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you aren't able to purchase one, try to keep the temperature indoors as close to the outside temperature as you can.
  • When it comes time to replace any part of your HVAC system, see if there are Energy Star-certified or other environmentally friendly options.
