Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or outdated likely needs professional attention for maintenance or replacement. Watch for these indicators that your system needs service:

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

If you see any of these HVAC issues, have a technician inspect your system. A local professional can detect problems and let you know whether whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in Clear Lake

What you spend on HVAC installation or maintenance is determined by your system style. Common HVAC unit styles include the following:

  • Split or mini-split: If your home doesn't have the right ductwork for central heating or air, 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 system functions in the same way as a normal split system, but has the benefit of being able to draw power from either gas or electric sources.
  • Heat pump: Heat pumps exchange warm and cool air between your home and outside. They don't create their own heating and cooling, so they work best in more moderate climates.
  • Packaged heating and air: Packaged HVAC systems are a smart choice for smaller houses. These systems have a single heating and cooling unit, normally located in an attic or basement. They're small, cost-effective, and easy to maintain.

HVAC maintenance prices differ based on the specific services required. HVAC systems can be complex and potentially require a number of services. Fees for typical jobs are as follows:

HVAC Unit TypeCost
Split$1,840-$4,690
Hybrid Split$3,728-$6,868
Heat Pump$2,886-$29,411
Packaged Heating and Air$242-$403

Ways to Save Money on HVAC Costs

It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Thankfully, there are steps you can take to reduce wear and tear on your system.

  • Keep your system clean. Cleaning your indoor evaporator coil, condenser fan blades, ductwork, and grills regularly helps keep your HVAC system working efficiently and reduces the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it starts to look dirty.
  • Monitor for potential problems. Monitoring the efficiency of your HVAC system — for instance by checking your thermostat settings and energy bills — helps you find and solve issues before they get too expensive.
  • 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 reduces the amount of work your HVAC system must perform.
  • Change filters regularly. Changing or cleaning your air filters every 1–3 months helps air flow efficiently through your HVAC system. You should also try to prevent dirt and debris from building up around the outdoor sections of your system.
ServiceCost
Filter Replacement$60-$161
Condensor Cleaning$1,208-$3,623
Thermostat Repair$81-$201
Ductwork Cleaning$386-$966

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 air conditioning and heating in your home.

Compare Multiple Bids

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

Check Credentials

Look for an HVAC company that employs qualified technicians who have the necessary training and licenses. HVAC contractors in all states need to 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." An individual 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 at the state level.

The state of Illinois doesn't have state-level licensing requirements for contractors. However, there may be local regulations, so make 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 check a provider's reviews and complaints with organizations such as Google Reviews, Yelp, and the Better Business Bureau (BBB). You want to hire a provider with positive reviews and a history of good customer service.

Understand Work Details

Always make sure you know what a company’s process is like. When HVAC repairs are needed, ask your provider to explain which parts need replacement and why. Confirm that your technician will clean and test the full system afterward to verify proper operation. When replacing your HVAC, have the provider describe the new features, model, brand, energy efficiency, and estimated installation time. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

Reputable HVAC companies back their work with warranties. Look at warranties from different companies, keeping in mind that more comprehensive coverage is better. Look for the company that provides the most coverage for a reasonable price.

Get Quote in Writing

Always get HVAC estimates in writing before work begins. A thorough quote covers costs for both materials and labor. Make sure that you understand all terms before signing the contract.

Frequently Asked Questions About HVAC in Clear Lake, IL

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

Generally, it's smart to schedule inspections 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 probably 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. Always keep your thermostat as close to the outside temperature as is comfortable, and try to adjust it only a few degrees at a time. You could also consider installing a smart thermostat.

It takes roughly 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 might take anywhere from a few hours up to two days. This timeline can be determined by the size of your home, how easily accessible your system is, and any new issues your technician uncovers.

For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. For a house over 1,000 square feet, central air will be more effective than window units for cooling.

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).

Normally, HVAC financing is provided by a third-party lender. If your HVAC company doesn't have financing options, you may consider taking out your own loan. Be sure to talk to a financial advisor and your HVAC company to find out what options are available and appropriate for your situation.

There are a number of 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.
  • 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 don't want to or can't buy one, try keeping your inside temperature as close to the outside temperature as is comfortable.
  • When it comes time to replace any part of your system, explore Energy Star-certified or other environmentally friendly options.
