Signs You May Need HVAC Repair or Replacement

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

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

Schedule an inspection if you notice any of these problems. A local technician can assess your system, detect problems, and decide whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Na-Au-Say

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

  • Split or mini-split: Homes without ductwork for central heating and cooling often have split or mini-split HVAC systems. These systems consist of internal units in each room to control temperature. These indoor units connect to an outdoor unit.
  • Hybrid split: A hybrid split HVAC system works almost the same as a standard split system. It has the advantage of being able to utilize either gas or electricity for power.
  • Heat pump: Heat pumps exchange hot and cold air between your home and outside. They don't generate their own heating and cooling, so they work more efficiently in more mild climates.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. They have a single heating and cooling unit, usually in a basement or attic. This unit is often compact, cost-effective, and easy to maintain.

The price of HVAC maintenance also varies depending on what 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 in a timely manner, but it can also be expensive. Luckily, there are steps you can take to reduce wear and tear on your system.

  • Keep your system clean. Keeping your condenser fan blades, indoor evaporator coil, ductwork, and grills clean enables your HVAC system to function properly and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your HVAC system when you notice it starting to get dirty.
  • 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 some heat from getting inside. Doing both helps minimize the demand on your HVAC.
  • Change filters regularly. Switching out or cleaning your air filters every 30–90 days helps air flow smoothly through your HVAC system. You should also try to prevent dirt and debris from building up around the outdoor sections of your system.
  • Monitor for potential problems. Monitoring 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$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 the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can keep your system running efficiently, providing you with effective heating and cooling for your home.

Compare Multiple Bids

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

Check Credentials

When picking an HVAC provider, choose one with technicians that have the proper training, licenses, and experience. 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 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 confirm that your contractor meets all the requirements. You can also verify an Illinois business license on the Secretary of State's website. Checking reviews on the Better Business Bureau (BBB), Yelp, Google Reviews, and similar sites can help your decision. Choose a provider with great reviews and reports of positive experiences from customers.

Understand Work Details

It’s important to know what the work process will look like. For HVAC repairs, the company should explain the specific parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to guarantee everything is working correctly. When replacing your HVAC, have the contractor explain the new energy efficiency, features, brand, estimated installation time, and model. Before signing paperwork, make sure you understand how your provider will determine the right system size for your home and what the price will be.

Compare Warranties

Reliable HVAC companies provide warranties for their work. Broader coverage is better, so make sure to compare warranties between providers. Choose the one that offers the best coverage at a fair cost.

Get Quote in Writing

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

Frequently Asked Questions About HVAC in Na-Au-Say, IL

You should have your HVAC system inspected about twice a year. After completing their 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, unusual smells, or strange noises. If your system has ductwork, it should be inspected every few years.

Usually, you should have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared 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. During all seasons, keep your thermostat as close to the outside temperature as is comfortable, and try to adjust it only a few degrees at once. You could also consider a smart thermostat.

It takes around one to three days to have your HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this can take between half a day and two days. This timeline can be influenced by the size of your house, how easily accessible your system is, and any issues your technician runs into.

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 between 2.5 and 5 tons of capacity. Usually, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Typically, HVAC financing is offered through 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 your HVAC company and a financial advisor to learn what options are available and appropriate for your situation.

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.
  • Have regular inspections to take care of problems 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 don't want to or can't buy one, try keeping the temperature indoors as close to the outside temperature as you can.
  • When you need to replace part of your system, explore Energy Star-certified or similar environmentally friendly options.
