Signs You May Need HVAC Repair or Replacement

If your HVAC system is broken or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Watch for these indicators your system needs service:

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

If you're experiencing any of these HVAC issues, we recommend having a technician inspect your system. A local professional can detect problems and determine whether fixing or replacing your HVAC unit is the correct solution.

Cost of HVAC Installation and Maintenance in DeKalb

Your HVAC installation or maintenance cost changes depending on the style of unit. Common HVAC unit varieties 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 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 much like a standard split system, but has the capacity to draw on either electricity or gas for power.
  • Heat pump: Heat pumps move hot and cold air between your home and the outside. These systems don't produce their own heat or AC, so they work better in milder climates.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. These systems have a single combined AC and heating, normally located in a basement or attic. They're compact, energy-efficient, and easy to maintain.

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

HVAC Unit TypeCost
Split$1,850-$4,715
Hybrid Split$3,748-$6,905
Heat Pump$2,902-$29,570
Packaged Heating and Air$243-$405

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. Fortunately, there are some steps you can take to slow the wear and tear on your HVAC.

  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months helps warm your home with passive solar heating. Closing the blinds during the summer helps prevent the same heat from getting inside. Doing both helps minimize the demand on your HVAC.
  • Change filters regularly. Air flows best through your HVAC system when you replace or clean the filters every 1–3 months. Also try not to let debris pile up on the outside areas of your HVAC.
  • Keep your system clean. Regularly cleaning grills, ductwork, condenser fan blades, and indoor evaporator coil helps keep your HVAC system running efficiently and reduces your risk of mold. The National Air Duct Cleaners Association recommends cleaning your heating and cooling system when it starts to look dirty.
  • Monitor for potential problems. Keeping a close eye on the efficiency of your HVAC system — for instance by reviewing your thermostat settings and energy bills — helps you identify and fix problems before they get too expensive.
ServiceCost
Filter Replacement$61-$162
Condensor Cleaning$1,214-$3,643
Thermostat Repair$81-$202
Ductwork Cleaning$389-$971

How To Choose a Local HVAC Company

Knowing the indicators of a good HVAC company is important. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling 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

Look for an HVAC company that employs qualified technicians who have the necessary training and licenses. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians 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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.

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 the requirements. You can verify an Illinois business license on the Secretary of State's website. You should also look at reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with glowing reviews and reports of good customer experiences.

Understand Work Details

Always make sure you know what a company’s process looks like. When getting HVAC repairs, ask your provider to list which parts require replacement and why. Confirm that your technician will clean and test the full system afterward to ensure proper operation. When replacing your HVAC, have the provider describe the new brand, features, energy efficiency, model, and estimated installation time. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

Good HVAC companies offer warranties on service and equipment installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers the best protection within your budget.

Get Quote in Writing

Always get quotes for HVAC service in writing before committing to a provider. An itemized quote should cover both labor and materials. Make sure you review all terms before signing a contract.

Frequently Asked Questions About HVAC in DeKalb, IL

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

The best times to have your HVAC system inspected 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 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. During all seasons, 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 could also consider getting a smart thermostat.

It takes roughly one to three days to have an HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this may take between half a day and two days. This timeline will be affected by the size of your house, the accessibility of your system, and any new issues your technician runs into.

Your HVAC company may provide financing options via a third-party lender, or you might be able to obtain your own loan. It's a good idea to discuss payment options with a financial advisor and your HVAC company to make sure that you find the best option for you.

There are a number of 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.
  • 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 your inside temperature as close to the outside temperature as you can.
  • When replacing part of your system, see if there are Energy Star-certified or other environmentally friendly options.
