Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or nearing the end of its lifespan, you may need to hire an HVAC contractor for repairs or replacement. Look for these common indicators that your system requires professional attention:

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

These HVAC red flags indicate that you should have your system evaluated. A local company can complete an inspection, diagnose problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Moraine

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

  • Split or mini-split: If your home doesn’t have 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 very similarly to a standard split system. It has the benefit of being able to utilize either electricity or gas for power.
  • Heat pump: Heat pumps work by circulating 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 work best in smaller homes. They consist of a single combined air conditioner and heating unit, commonly located in an attic or basement. This unit is typically space-saving, energy-efficient, and straightforward to maintain.

HVAC maintenance prices vary depending on what services are needed. HVAC systems are complex and can require different kinds of maintenance. Costs for some 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

HVAC upkeep is 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. Leaving your blinds open during the winter helps warm your home with passive solar heating. Closing the blinds in warmer seasons helps prevent the heat from getting inside. Doing both helps minimize the strain on your HVAC.
  • Monitor for potential problems. Monitoring your system for problems — for example, by checking your thermostat and energy bills regularly — helps you catch issues before they get too expensive.
  • Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 1–3 months. Also try not to let debris pile up on the outdoor parts of your HVAC.
  • Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, grills, and ductwork clean helps your HVAC system function effectively and lowers your risk of mold. The National Air Duct Cleaners Association suggests cleaning your home's HVAC system when you notice it starting to get dirty.
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 what makes a trustworthy HVAC company is key for an easy installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.

Compare Multiple Bids

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

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, contractors must pass an exam (the specific 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.

The state of Illinois doesn't have state-level licensing requirements for contractors. 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. Checking reviews on Google Reviews, the Better Business Bureau (BBB), Yelp, and similar sites can aid your decision as well. Choose a company with great reviews and reports of positive experiences from customers.

Understand Work Details

Always make sure you know the details of your project. When HVAC repairs are required, your provider should specify which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are done to ensure that it’s working properly. When replacing your HVAC, ask your contractor to provide details on the new energy efficiency, model, brand, estimated installation time, and features. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

A trustworthy HVAC company will stand behind its repair services and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully compare the fine print between contractors and choose the company that provides the most protection at a reasonable price.

Get Quote in Writing

Always get estimates for HVAC service in writing before committing to a provider. An itemized quote should cover both materials and labor. Make sure you review all terms before signing a contract.

Frequently Asked Questions About HVAC in Moraine, IL

You should have your HVAC system inspected about twice a year. At the time of the inspection, your technician will tell you if any services are required. You should also schedule an inspection if you notice new issues such as unusual smells, strange noises, or leaks. If your home has ductwork, you should have it inspected every few years.

Generally, 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 making it easier for your HVAC system to maintain the temperature of your home. Always keep your thermostat as close to the outside temperature as is comfortable, and avoid making drastic changes — adjust it only a few degrees at a time. You may also consider purchasing a smart thermostat.

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. Typically, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.

Usually, HVAC financing is through a third-party lender. If your HVAC company doesn't offer these options, 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 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 on a regular basis.
  • Have regular inspections to take care of issues as they come up.
  • Keep your attic well-ventilated and make sure all doors and windows are well-sealed.
  • Install a smart thermostat. If you don't want to or can't buy one, try to keep your inside temperature as close to the outside temperature as is comfortable.
  • When it comes time to replace any part of your system, see if there are Energy Star-certified or other environmentally friendly options.
