Signs You May Need HVAC Repair or Replacement

An HVAC system that's malfunctioning or outdated likely needs professional attention for maintenance or replacement.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

  • Strange noises when the system turns on
  • Thermostat malfunctions or temperature control issues
  • Corrosion, rust, or cracking
  • Frequent breakdowns and need for repairs
  • 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 these HVAC red flags, your system evaluated. A local technician can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Oswego

What you spend on HVAC installation or maintenance varies based on your system type. Common HVAC unit styles include the following:

  • Split or mini-split: If your home lacks the right ductwork for central air or heating, you likely have a split HVAC system. Split or mini-split systems consist of internal 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 functions very similarly to a standard split system. It has the advantage of being able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps work by transferring hot and cold air between your home and the outdoors. These systems don't create heat or air conditioning themselves, and are better for more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single heating and cooling unit, typically in a basement or attic. This unit is often small, 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 complicated and may 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 when they are required, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.

  • Keep your system clean. Regularly cleaning condenser fan blades, indoor evaporator coil, grills, and ductwork helps your HVAC system run efficiently and lowers the risk of mold. The National Air Duct Cleaners Association advises cleaning your HVAC system when it starts to look dirty.
  • Change filters regularly. Changing your air filters or washing them every 1–3 months allows smooth air circulation through your system. Also try to keep debris from accumulating on the outdoor sections of your HVAC.
  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you identify and fix problems before they get too expensive.
  • Change the position of your blinds seasonally. Leaving your blinds open during the colder months allows passive solar heating to warm your home. Closing the blinds during the summer helps prevent the same heat from getting inside. Doing both helps decrease the demand on your 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

It's important to know what makes a good HVAC company. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can fix your system, providing you with effective air conditioning and heating for your home.

Compare Multiple Bids

Request estimates from at least three HVAC companies. Explain your issues and ask if specialists can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid contractors that pressure you or demand payment before work.

Check Credentials

When hiring an HVAC provider, choose one with technicians that have the right training, licenses, and experience. HVAC contractors in all states 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." Contractors 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 on a state-by-state basis.

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

Understand Work Details

Make sure you know the details of any project before it begins. 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. For replacement, ask the contractor to explain the new HVAC system features, estimated installation time, energy efficiency, model, and brand. Before work begins, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.

Compare Warranties

Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that offers the best protection for the fairest price.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Oswego, IL

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

Generally, it's a good idea to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. 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 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 might also consider getting 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 be based on things like the size of your house, how easily accessible different parts of the system are, and whether your technician runs into 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 an air conditioning unit with around 2.5 to 5 tons of capacity. In general, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

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

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

  • Make sure your air ducts remain clean, and change or clean your air filters on a regular basis.
  • Schedule regular inspections to take care of issues 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 your inside temperature as close to the outside temperature as you can.
  • When replacing part of your HVAC system, see if there are Energy Star-certified or other environmentally friendly options.
