Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Watch out for these common signs that your HVAC needs service:

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

If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, diagnose problems, and advise you whether you should repair or replace your HVAC unit.

Cost of HVAC Installation and Maintenance in Northfield

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

  • Split or mini-split: If your home lacks the right ductwork for central heating or air, you likely have a split HVAC system. Split or mini-split systems consist of interior 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 move hot and cold air between your home and the outside. These systems don't generate their own heat or AC, so they work better in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single heating and cooling unit, usually in an attic or basement. This unit is often compact, energy-efficient, and easy to maintain.

HVAC maintenance costs differ depending on what services are needed. HVAC systems are complex and might require different maintenance services. Prices for common services are as follows:

HVAC Unit TypeCost
Split$1,973-$5,030
Hybrid Split$3,998-$7,366
Heat Pump$3,096-$31,544
Packaged Heating and Air$259-$432

Ways to Save Money on HVAC Costs

Taking care of necessary HVAC repairs and replacements when needed is crucial, but can be expensive. Fortunately, there are actions you can take to minimize wear and tear over time on your system.

  • Keep your system clean. Regularly cleaning condenser fan blades, grills, ductwork, 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 HVAC system when it starts to look dirty.
  • Monitor for potential problems. Monitor your system for issues, for example by consistently checking your thermostat and energy bills. This enables you to address problems before they get out of hand.
  • 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 outdoor portions of your HVAC system as much as possible.
  • Change the position of your blinds seasonally. During winter, leaving your blinds open allows your home to benefit from passive solar heating. In the summer, keeping your blinds shut helps to block out heat. Doing both lowers the amount of work your HVAC system needs to do.
ServiceCost
Filter Replacement$65-$173
Condensor Cleaning$1,295-$3,886
Thermostat Repair$86-$216
Ductwork Cleaning$414-$1,036

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 air conditioning and heating in your home.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.

Check Credentials

When selecting 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 mandatory 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 the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.

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 verify that your contractor meets all of the requirements. You can also 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 the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with glowing feedback and good customer testimonials.

Understand Work Details

Make sure you understand the details of any project before starting. For HVAC repairs, have your provider detail which parts require replacement and why. Get confirmation that your technician will clean and test the entire system after the repair to ensure that everything works. When getting a replacement, ask the contractor to explain the new HVAC system estimated installation time, model, features, energy efficiency, and brand. 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

Reputable HVAC companies stand behind their work with warranties. Look at warranties from different companies, remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a reasonable price.

Get Quote in Writing

Get a written proposal before HVAC work starts. A full quote includes both labor and material costs. Make sure you understand and agree to all terms before signing the contract.

Frequently Asked Questions About HVAC in Northfield, IL

Normally, you should have your HVAC system inspected twice a year. After that inspection, your HVAC technician will tell you what services are needed. You should also call a technician if you start to notice any issues, such as unusual smells, leaks, or strange noises. If your home has ductwork, 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 helps get your system ready for the summer and winter, the times of the year when it 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. During all seasons, keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at a time. You may also consider getting a smart thermostat.

Generally, whole-system HVAC installation or replacement takes between one and three days. Installing or replacing a furnace or air conditioning unit may take anywhere from a few hours up to two days. The exact amount of time will vary depending on things like the size of your home, how easily accessible different parts of the system are, and whether your technician finds any problems.

For a 2,000-square-foot home, you'll need between 2.5 and 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 may provide financing options through a third-party lender, or you may be able to obtain your own loan. It's smart 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 several ways you can make your HVAC system more energy-efficient:

  • Keep your air ducts clean and clean or change your air filters regularly.
  • Schedule regular inspections to take care of issues as they come up.
  • Make sure your doors and windows are well-sealed and keep your attic well-ventilated.
  • 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 replacing part of your system, explore Energy Star-certified or similar environmentally friendly options.
