10 Best HVAC Companies in Normal, IL

Signs You May Need HVAC Repair or Replacement

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

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

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can diagnose problems and determine whether repair or full HVAC replacement is the better solution.

Cost of HVAC Installation and Maintenance in Normal

The cost of HVAC installation or maintenance changes depending on the type of unit you have. Common types of HVAC units include the following:

• Split or mini-split: Homes without ductwork for central air often have split or mini-split HVAC systems. These systems consist of interior units in each room to control temperature, which all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the advantage of being able to utilize either gas or electricity for power.
• Heat pump: Heat pumps transfer warm and cool air between your home and outside. These systems don't produce their own heat or AC, so they work better in moderate climates.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single heating and cooling unit, typically in a basement or attic. This unit is often compact, energy-efficient, and easy to maintain.

HVAC expenses vary based on the work needed. HVAC systems are complicated and may need a number of types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

It’s important to make any essential HVAC fixes or replacements as needed, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.

• Change filters regularly. Changing your air filters or washing them every 30–90 days allows efficient air circulation through your system. You should also try to keep debris from accumulating on the outside components of your HVAC.
• Keep your system clean. Keeping your grills, indoor evaporator coil, condenser fan blades, and ductwork clean helps your system run and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system whenever it begins to look dirty.
• Change the position of your blinds seasonally. Keeping your blinds open in the winter helps you take advantage of passive solar heating. Keeping them closed in the summer helps keep some of this heat out. Both of these measures help reduce the amount of work your HVAC system needs to do.
• Monitor for potential problems. Monitor your system for issues, for example by consistently checking your thermostat and energy bills. This allows you to address problems before they get too expensive.

How To Choose a Local HVAC Company

Knowing what to look for in an HVAC company is crucial 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. Describe the issues and have technicians visit to inspect your HVAC system if possible. Compare the providers' explanations, solutions, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand payment upfront.

Check Credentials

Choose an HVAC company with highly trained technicians who have proper licensing and experience. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, individuals 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 by the state.

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 the requirements. You can verify an Illinois business license on the Secretary of State's website. You should also check a company's reviews and complaints on sites such as the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with positive feedback and good customer testimonials.

Understand Work Details

Make sure you know the details of any project before starting. For HVAC repairs, have your provider list which parts require replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. When replacing your HVAC, ask the contractor to describe the new model, estimated installation time, energy efficiency, brand, and features. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Good HVAC companies offer warranties on service and installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the most comprehensive protection within your budget.

Get Quote in Writing

Get a written proposal before HVAC work begins. A comprehensive quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.
