10 Best HVAC Companies in Alton, IL

Signs You May Need HVAC Repair or Replacement

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

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

Schedule an inspection if you notice any of these issues. A local technician can assess your system, detect problems, and determine whether you need to fix or replace your HVAC.

Cost of HVAC Installation and Maintenance in Alton

HVAC installation or maintenance costs vary 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 regulate 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 advantage of being able to utilize either electricity or gas for power.
• Heat pump: Heat pumps circulate warm and cold air between your home and outside. They don't produce their own heat or AC, so they function best in temperate climates.
• Packaged heating and air: Packaged HVAC systems are good for smaller houses. Packaged systems consist of a single heating and cooling unit that's typically located in a basement or attic. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance prices vary depending on what services are needed. HVAC systems are complicated and might require different kinds of maintenance. Prices for some common services are as follows:

Ways to Save Money on HVAC Costs

It’s important to complete repairs or full-system HVAC replacements as needed, though they can be expensive. The good news is that homeowners have ways to minimize progressive deterioration and reduce the frequency of breakdowns.

• Keep your system clean. Cleaning your grills, ductwork, indoor evaporator coil, and condenser fan blades 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. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, lets you resolve them before they get too expensive.
• Change the position of your blinds seasonally. Leaving your blinds open during the winter allows passive solar heating to warm your home. Closing the blinds in warmer seasons helps prevent some heat from getting inside. Doing both helps lessen the demand on your HVAC.
• Change filters regularly. Replacing or cleaning your air filters every 1–3 months helps air flow efficiently through your HVAC system. We also recommend regularly clearing dirt and debris away from the outside areas of your system.

How To Choose a Local HVAC Company

Knowing the right things to look for in an HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent coolig and heating year-round.

Compare Multiple Bids

Request estimates from at least three HVAC contractors. Describe your issues and ask if technicians can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid contractors that pressure you or demand payment before work.

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. HVAC contractors in all states have federal requirements from 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 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 the requirements. You can also verify an Illinois business license on the Secretary of State's website. Checking reviews on Yelp, the Better Business Bureau (BBB), Google Reviews, and similar sites can help your decision. Choose a provider with stellar reviews and stories of positive 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 specific parts that need replacement and why. Confirm that your technician will clean and test the full system afterward to make sure everything is operating properly. When replacing your HVAC system, ask the installation company to provide details on the new estimated installation time, energy efficiency, features, brand, and model. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost 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 providers and pick the one that offers the most comprehensive protection for the fairest price.

Get Quote in Writing

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