Signs You May Need HVAC Repair or Replacement

If your HVAC system is having issues or getting old, it likely needs repairs or replacement from an HVAC company. Look for these signs your system needs service:

  • Temperature control issues or thermostat malfunctions
  • Poor air circulation or uneven heating/cooling
  • Cracking, rust, or corrosion
  • Unusually high energy bills
  • Odd noises when the system turns 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 identify problems and determine whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Waterloo

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

  • Split or mini-split: If your home lacks the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of indoor units that control the temperature in individual rooms. These interior units are all connected to an outdoor unit.
  • Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It gives flexibility by providing the option to draw on either electricity or gas for energy.
  • Heat pump: Heat pumps transfer warm and cool air between your home and the outside. These systems don't generate their own heat or AC, so they work more effectively in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems are more popular in smaller homes. Packaged systems consist of a single combined heating and cooling unit, normally located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance costs vary depending on the particular service needed. HVAC systems are complicated and may require different maintenance services. Prices for common services are as follows:

HVAC Unit TypeCost
Split$1,929-$4,919
Hybrid Split$3,909-$7,203
Heat Pump$3,027-$30,845
Packaged Heating and Air$253-$422

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 slow the wear and tear on your system.

  • Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, allows you to resolve them before they get too expensive.
  • Keep your system clean. Keeping your condenser fan blades, grills, ductwork, and indoor evaporator coil clean helps your HVAC system function properly and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your HVAC when you notice things starting to get dirty.
  • Change filters regularly. Switching out 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.
  • Change the position of your blinds seasonally. During winter, leave your blinds open so your home benefits from passive solar heat. In summer, keep blinds shut to block out heat. Doing both helps minimize the amount of work your HVAC system is required to do.
ServiceCost
Filter Replacement$63-$169
Condensor Cleaning$1,267-$3,800
Thermostat Repair$84-$211
Ductwork Cleaning$405-$1,013

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 fix your system, providing you with effective air conditioning and heating in your home.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe the issues and have specialists visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, a contractor must pass an exam (the type of exam depends on the kind of equipment they plan 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 by the state.

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

Understand Work Details

It’s important to understand what the work process will look like. For HVAC repairs, the company should list the exact parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to guarantee everything is working correctly. When replacing your HVAC, request that the company explain the new brand, features, estimated installation time, energy efficiency, and model. Before work starts, 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

Reliable HVAC companies offer warranties on repairs and equipment installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that provides the best protection for a fair price.

Get Quote in Writing

Always get estimates for HVAC service in writing before work begins. A comprehensive quote should cover both labor and materials. Make sure you agree to all terms before signing a contract.

Frequently Asked Questions About HVAC in Waterloo, IL

You should have your HVAC system inspected approximately twice yearly. Following an inspection, your technician will tell you what services are needed. You should also have your system inspected if you notice new issues such as unusual smells, strange noises, or leaks. If your system has ductwork, it should be inspected every few years.

Normally, you should schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it probably sees the most use.

You can save energy throughout the year by reducing the amount of work it takes for your HVAC system to maintain your home's temperature. 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 may also consider 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 can take as little as half a day or as much as two days. The exact amount of time will vary depending on things like the size of your home, how easily accessible different sections are, and whether your technician finds any problems.

Your HVAC company may offer financing options through a third-party lender, or you may be able to obtain a loan on your own. It's a good idea 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:

  • Keep ductwork clean, and change or clean your air filters on a regular basis.
  • Schedule regular inspections to take care of problems 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 keeping your inside temperature as close to the outside temperature as you can.
  • When you need to replace part of your HVAC system, see if there are Energy Star-certified or similar environmentally friendly options.
