Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or outdated likely needs professional attention for maintenance or replacement. Watch for these signals that your system needs service:

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

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

Cost of HVAC Installation and Maintenance in Thornton

HVAC installation or maintenance costs vary depending on your system. Common HVAC unit varieties include the following:

  • Split or mini-split: If your home lacks the ductwork for central heating and cooling, you likely have a split or mini-split system instead. Split HVAC systems have internal units in each room to manage temperature. These connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system functions in the same way as a normal split system, but has the advantage of being able to draw power from either gas or electric sources.
  • Heat pump: Heat pumps circulate warm and cold air between your home and the outdoors. They don't generate their own heat or AC, so they perform best in temperate climates.
  • Packaged heating and air: Packaged HVAC systems are a great choice for smaller homes. They have a single heating and cooling unit, usually in an attic or basement. This unit is often space-saving, cost-effective, and easy to maintain.

HVAC maintenance costs differ depending on the particular service needed. HVAC systems are complicated and may require different kinds of maintenance. Costs for common services are as follows:

HVAC Unit TypeCost
Split$1,960-$4,995
Hybrid Split$3,971-$7,315
Heat Pump$3,074-$31,328
Packaged Heating and Air$257-$429

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be expensive. Fortunately, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.

  • Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the amount of work your HVAC system needs to do.
  • Change filters regularly. Cleaning or replacing your air filters every 1–3 months helps air flow smoothly through your system. You should also try to keep debris away from the outside areas of your HVAC system as much as possible.
  • Keep your system clean. Regularly cleaning condenser fan blades, grills, indoor evaporator coil, and ductwork helps keep your HVAC system running efficiently and reduces the risk of mold. The National Air Duct Cleaners Association advises cleaning your system when it starts to look dirty.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, lets you resolve them before they get too expensive.
ServiceCost
Filter Replacement$64-$172
Condensor Cleaning$1,286-$3,859
Thermostat Repair$86-$214
Ductwork Cleaning$412-$1,029

How To Choose a Local HVAC Company

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

Compare Multiple Bids

Request estimates from three or more HVAC contractors. Describe your issues and ask if specialists can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.

Check Credentials

Choose an HVAC company with skilled technicians who have proper licensing and experience. 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 type of 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.

There are no state-level licensing requirements for contractors in Illinois. However, there may be local regulations. Be sure to check with your municipal government to confirm that your contractor meets all of the requirements. You can also verify an Illinois business license on the Secretary of State's website. Reviewing feedback on the Better Business Bureau (BBB), Google Reviews, Yelp, and similar sites can assist your decision. Choose a company with stellar reviews and reports of positive customer experiences.

Understand Work Details

It’s important to understand what the work process will look like. For HVAC repairs, the company should explain the exact parts that need replacement and why. Confirm that your technician will clean and test your system afterward to guarantee everything is working correctly. When replacing your HVAC, ask the provider to explain the new energy efficiency, model, brand, features, and estimated installation time. Before signing a contract, be 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. Broader coverage is better, so make sure to review warranties between companies. Choose the one that provides the most comprehensive coverage at a fair cost.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A detailed quote will cover costs for both labor and materials. Ensure that you understand all terms before signing the contract.

Frequently Asked Questions About HVAC in Thornton, 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 needed. You should also call a technician if you notice any new issues, like leaks, unusual smells, 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 the spring and fall. Technicians are generally less busy during these times, which makes it easier to get an appointment. This also helps get your system ready for the summer and winter, when it typically gets 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. Always keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at once. You may 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 can take as little as half a day or as much as two days. The exact amount of time will vary depending on factors like the size of your home, how easily accessible different sections are, and whether your technician finds any problems.

Your HVAC company might have financing options through a third-party lender, or you might choose 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:

  • Make sure your air ducts remain 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 keeping your inside temperature as close to the outside temperature as is comfortable.
  • When replacing part of your system, explore Energy Star-certified or similar environmentally friendly options.
