Signs You May Need HVAC Repair or Replacement

If your HVAC system is having issues or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Look for these indicators your system needs service:

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

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

Cost of HVAC Installation and Maintenance in Grayslake

HVAC installation or maintenance prices vary depending on your system. Common HVAC unit types 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 regulate the temperature in individual rooms, and that 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 advantage of being able to draw power from either electric or gas sources.
  • Heat pump: Heat pumps transfer warm and cool air between your home and outside. They don't generate their own heating and cooling, so they work more effectively in more temperate climates.
  • Packaged heating and air: Packaged HVAC systems are a great choice for smaller houses. They have a single cooling and heating unit, normally in a basement or attic. This unit is often small, cost-effective, and easy to maintain.

HVAC maintenance prices differ depending on the particular service needed. HVAC systems are complicated and might require different maintenance services. Fees 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 HVAC and lower future maintenance needs.

  • 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 lowers the amount of work your HVAC system must perform.
  • Change filters regularly. Changing your air filters or washing them every 30–90 days allows smooth air circulation through your system. Also try to keep debris from accumulating on the outdoor sections of your HVAC.
  • Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, lets you resolve them before they get out of hand.
  • Keep your system clean. Keeping your indoor evaporator coil, grills, condenser fan blades, and ductwork clean helps your system function optimally and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system whenever it begins to look 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 to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and make sure your system provides reliable heating and air conditioning for your home.

Compare Multiple Bids

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

Check Credentials

Choose an HVAC company with highly trained technicians who have appropriate licensing and experience. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual must pass an exam (the specific exam depends on what 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.

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 confirm that your contractor meets all of the requirements. You can verify an Illinois business license on the Secretary of State's website. Checking reviews on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can aid your decision as well. Choose a provider with great reviews and reports of positive customer experiences.

Understand Work Details

Always make sure you understand the details of your project. For HVAC repairs, your provider should detail which parts require replacement and why. Confirm that your technician will clean and test the system after repairs are completed to ensure that it’s working properly. When replacing your HVAC, request that the company explain the new estimated installation time, features, model, brand, and energy efficiency. Before signing paperwork, make 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

A trustworthy HVAC company will back its repair work and installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully compare warranty terms between contractors and choose the provider that offers the most protection at a reasonable price.

Get Quote in Writing

Get written bids before starting any HVAC work. The quote should include costs for both labor and materials. Review all terms carefully before signing.

Frequently Asked Questions About HVAC in Grayslake, IL

You should have your HVAC system inspected twice a year. After completing their inspection, your technician will tell you if any services are required. You should also have your system inspected if you start noticing issues such as unusual smells, strange noises, or leaks. If your system has ductwork, it should be inspected every few years.

Normally, it's a good idea 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 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 you can, and avoid making drastic changes — adjust it only a few degrees at a time. You might also consider installing a smart thermostat.

Generally, HVAC installation or replacement takes one to three days for the entire system. Installing or replacing a furnace or air conditioning unit takes anywhere from about half a day up to two days. The exact amount of time will be based on things like the size of your house, 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 want 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. In general, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.

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

There are a number of ways you can make your HVAC system more energy-efficient:

  • Make sure your air ducts remain clean, and clean or change your air filters regularly.
  • Schedule regular inspections to take care of issues 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 to keep the temperature indoors as close to the outside temperature as is comfortable.
  • When you need to replace part of your HVAC system, explore Energy Star-certified or other environmentally friendly options.
