10 Best HVAC Companies in Norwalk, IA

Signs You May Need HVAC Repair or Replacement

A malfunctioning or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Watch out for these common signs that your HVAC needs service:

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

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

Cost of HVAC Installation and Maintenance in Norwalk

What you spend on HVAC installation or maintenance varies based on your system type. Common HVAC unit styles include the following:

• Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you probably have a split or mini-split system. Split systems have internal units in each room to control temperature. These indoor units 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 having the capability to use either electricity or gas for power.
• Heat pump: Heat pumps transfer hot and cold air between your home and the outside. These systems don't generate their own heat or AC, so they work better in moderate climates.
• Packaged heating and air: Packaged HVAC systems work well 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 compact, cost-effective, and straightforward to maintain.

The cost of HVAC maintenance also depends on what kind of work you're having done. HVAC systems are complex and can require different kinds of maintenance. The cost of some common repairs is as follows:

Ways to Save Money on HVAC Costs

It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Luckily, there are steps you can take to reduce wear and tear on your HVAC.

• Change filters regularly. Replacing your air filters or washing them every 30–90 days allows effective air circulation through your system. Also try to keep debris from accumulating on the external parts of your HVAC.
• Change the position of your blinds seasonally. Keeping your blinds closed in the summer helps block out passive solar heat. Keeping them open in the winter helps you take advantage of this same heat. Both of these measures help reduce the strain on your HVAC system.
• 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.
• Keep your system clean. Keeping your indoor evaporator coil, grills, condenser fan blades, and ductwork clean helps your HVAC system function effectively and lowers the risk of mold. The National Air Duct Cleaners Association suggests cleaning your HVAC when you notice it starting to get dirty.

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. A properly licensed contractor with the right experience will give you confidence that they can fix your system, providing you with effective heating and cooling in 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. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual must pass an exam (the specific 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 by the state.

In Iowa, HVAC contractors must be licensed by the Iowa Plumbing and Mechanical Systems Board and registered with the Iowa Division of Labor. Contractors must be both bonded and insured. An individual can be licensed as an apprentice, journeyperson, or master; apprentices and journeypersons must be supervised by a licensed master. You should also check a company's reviews and complaints with organizations such as Yelp, the Better Business Bureau (BBB), and Google Reviews. Choose a company with positive reviews and a history of good customer service.

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. Confirm that your technician will clean and test the entire system after the repair to ensure that everything works. When getting a replacement, ask your contractor to explain the new HVAC system features, energy efficiency, estimated installation time, model, and brand. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Trustworthy HVAC companies provide warranties for their work. The broader the coverage, the better, so make sure to compare warranties between providers. Choose the one that provides the most comprehensive coverage at a reasonable cost.

Get Quote in Writing

Always get quotes for HVAC service in writing before committing to a provider. A detailed quote should cover both materials and labor. Make sure you agree to all terms before signing a contract.
