10 Best HVAC Companies in Greenfield, WI

Signs You May Need HVAC Repair or Replacement

If your home's HVAC system is malfunctioning or nearing the end of its lifespan, you may need to hire an HVAC contractor for repairs or replacement. Watch for these common signs that your system requires professional attention:

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

If you notice any of the above, have a local HVAC technician inspect your system. They can diagnose problems and recommend whether repair or full HVAC replacement is required.

Cost of HVAC Installation and Maintenance in Greenfield

Your HVAC installation or maintenance cost fluctuates depending on the style of unit. Common HVAC unit types include the following:

• Split or mini-split: If your home doesn’t have the ductwork for central air or heating, you probably have a split or mini-split system instead. Split HVAC systems have indoor units in each room to control temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC unit operates similarly to a regular split system. It provides flexibility by having the option to draw on either electricity or gas for energy.
• Heat pump: Heat pumps work by circulating hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are more suited to more moderate climates.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single cooling and heating unit, usually in a basement or attic. This unit is often compact, energy-efficient, and easy to maintain.

HVAC maintenance costs vary depending on what services are needed. HVAC systems are complex and may require different maintenance services. Costs for common services 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 methods to decrease the effect of wear and tear and reduce the frequency of breakdowns.

• Change filters regularly. Cleaning or replacing your air filters every 30–90 days helps air flow efficiently through your system. Also try to keep debris away from the outdoor portions of your HVAC system as much as possible.
• 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 too expensive.
• Keep your system clean. Keeping your ductwork, grills, indoor evaporator coil, and condenser fan blades clean helps your HVAC system function effectively and lowers your risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC when you notice things starting to get dirty.
• 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 during the summer helps prevent some heat from getting inside. Doing both helps reduce the demand on your HVAC.

How To Choose a Local HVAC Company

Knowing the right things to look for in an HVAC company is key for a smooth repair or installation. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent heating and cooling year-round.

Compare Multiple Bids

Get quotes from at least three HVAC companies. 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

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." Contractors 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 on a state-by-state basis.

There are no mandatory state-level licensing requirements for HVAC contractors in Wisconsin – contractors simply need to register with the Department of Safety and Professional Services. An individual can optionally become certified as an HVAC Qualifier, which requires four years of education, experience, or a combination of the two, and may allow them to be exempt from some local regulations. Whether your technician is an HVAC Qualifier or not, you should be sure that they meet any local requirements. Checking reviews on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can assist your decision. Choose a company with stellar reviews and stories of positive experiences from customers.

Understand Work Details

Always make sure you understand the details of any project. For HVAC repairs, your provider should list which parts require replacement and why. Confirm that your technician will clean and test your system after repairs are done to ensure that it’s working properly. When replacing your HVAC, ask the contractor to provide details on the new energy efficiency, brand, model, estimated installation time, and features. Before work begins, 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 provide warranties for their work. The broader the coverage, the better, so make sure to review warranties between providers. Choose the one that provides the most comprehensive coverage at a fair cost.

Get Quote in Writing

Get written quotes before beginning HVAC work. The quote should cover costs for both labor and materials. Read all terms carefully before signing.
