Signs You May Need HVAC Repair or Replacement

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

  • Odd noises when the system turns on
  • Higher than normal energy bills
  • Uneven heating/cooling or poor air circulation
  • Temperature control issues or thermostat malfunctions
  • Frequent breakdowns and need for repairs
  • Corrosion, cracking, or rust
  • Refrigerant leaks
  • An HVAC system that's over 15 years old

If you notice any of the above, have a local HVAC technician inspect your system. They can diagnose problems and let you know whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Mount Vernon

Your HVAC installation or maintenance cost changes depending on the type of unit. Common HVAC unit types include the following:

  • Split or mini-split: If your home doesn't have the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of indoor units that regulate the temperature in individual rooms. These interior units are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but has the capacity to draw on either electricity or gas for power.
  • Heat pump: Heat pumps exchange hot and cold air between your home and the outside. These systems don't generate their own heat or AC, so they work more effectively in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined air conditioner and heating unit, typically located in an attic or basement. This unit is typically space-saving, energy-efficient, and easy to maintain.

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

HVAC Unit TypeCost
Split$1,933-$4,928
Hybrid Split$3,917-$7,216
Heat Pump$3,033-$30,903
Packaged Heating and Air$254-$423

Ways to Save Money on HVAC Costs

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Thankfully, there are some steps you can take to slow the wear and tear on your system.

  • Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, allows you to resolve them before they get too expensive.
  • Change filters regularly. Changing your air filters or washing them every 30–90 days allows effective air circulation through your HVAC system. Also try to keep debris from accumulating on the external parts of your HVAC.
  • Keep your system clean. Cleaning your grills, indoor evaporator coil, ductwork, and condenser fan blades regularly helps keep your HVAC system working efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it begins to look dirty.
  • Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help decrease the work required from your home’s HVAC system.
ServiceCost
Filter Replacement$63-$169
Condensor Cleaning$1,269-$3,807
Thermostat Repair$85-$211
Ductwork Cleaning$406-$1,015

How To Choose a Local HVAC Company

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

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Explain the issues and have specialists visit to inspect your HVAC system if possible. Compare the providers' explanations, solutions, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand payment upfront.

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper 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 on a state-by-state basis.

The state of Illinois doesn't have state-level licensing requirements for contractors. However, there may be local regulations, so make sure to check with your municipal government to verify that your contractor meets all of the requirements. You can verify an Illinois business license on the Secretary of State's website. Always check a provider's reviews and complaints with organizations such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Choose a company with glowing reviews and stories of positive service experiences.

Understand Work Details

Make sure you understand the details of any project before starting. If HVAC repairs are required, have your provider detail which parts need replacement and why. Get confirmation that your technician will clean and test the system after the repair to verify that everything works. When getting a replacement, ask your contractor to explain the new HVAC system brand, model, features, estimated installation time, and energy efficiency. Before signing a contract, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Trustworthy HVAC companies stand behind their services with warranties. Compare warranties from different companies, keeping in mind that more comprehensive coverage is better. Look for the company that offers the most coverage for a reasonable price.

Get Quote in Writing

Always get estimates for HVAC service in writing before work begins. A comprehensive quote should cover both materials and labor. Make sure you agree to all terms before signing a contract.

Frequently Asked Questions About HVAC in Mount Vernon, IL

You should have your HVAC system inspected twice a year. At the time of the inspection, your technician will inform you what services are required. You should also have your system inspected if you notice new issues such as leaks, strange noises, or unusual smells. If your system has ductwork, it should be inspected every few years.

Generally, it's smart to schedule inspections 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 reducing the amount of power your HVAC system uses to maintain the temperature of your home. 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 a time. You may also consider purchasing a smart thermostat.

It takes around one to three days to have an HVAC system installed or replaced. If you need just a furnace or a single air conditioning unit, this might take anywhere from a few hours up to two days. This timeline will be determined by the size of your home, the accessibility of your system, and any new issues your technician discovers.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air is likely to be more effective for cooling than window units.

For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).

Your HVAC company might have financing options through a third-party lender, or you might be able to obtain your own loan. It's smart to discuss payment options with your HVAC company and a financial advisor to make sure that you're choosing the best option for you.

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

  • Keep ductwork clean, and clean or change 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 keeping the temperature indoors as close to the outside temperature as is comfortable.
  • When it comes time to replace any part of your HVAC system, explore Energy Star-certified or other environmentally friendly options.
