Today's Homeowner looks at dozens of datapoints on hvac companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
If your HVAC system is faulty or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Look for these indicators your system needs service:
If you notice any of these HVAC red flags, your system evaluated. A local technician can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.
The price of HVAC installation or maintenance changes depending on the kind of unit you have. Common types of HVAC units include the following:
The amount you spend on HVAC maintenance also depends on what kind of work you're having done. HVAC systems are complex and may require different kinds of maintenance. The cost of some common repairs is as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,904-$4,853 | |
| Hybrid Split | $3,857-$7,107 | |
| Heat Pump | $2,987-$30,434 | |
| Packaged Heating and Air | $250-$417 |
It's important to take care of HVAC repairs and replacements in a timely manner, but it can also be expensive. Fortunately, there are some steps you can take to reduce wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $62-$167 | |
| Condensor Cleaning | $1,250-$3,749 | |
| Thermostat Repair | $83-$208 | |
| Ductwork Cleaning | $400-$1,000 |
Knowing what makes a trustworthy HVAC company is crucial for a smooth installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.
Get quotes from at least three HVAC providers. Explain your issues and ask if specialists can inspect your system in person. Review each provider's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid contractors that pressure you or demand payment before work.
Look for an HVAC company that employs skilled technicians with the necessary training and licenses. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for any individual who helps "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 what kind of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled at the state level.
Wisconsin doesn't have any mandatory state-level requirements for HVAC contractors; all 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 exempt them from some local regulations. Whether your technician is an HVAC Qualifier or not, make sure that they meet any local requirements. You should also read reviews and complaints on sites like Google Reviews, Yelp, and the Better Business Bureau (BBB). Choose a company with positive reviews and testimonials about good customer experiences.
Always make sure you understand the details of your project. When HVAC repairs are required, your provider should list 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 system, have the provider describe the new estimated installation time, energy efficiency, brand, features, and model. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.
Reliable HVAC companies provide warranties for their work. Broader coverage is better, so make sure to review warranties between companies. Choose the one that offers the best coverage at a fair cost.
Always get quotes for HVAC service in writing before work begins. A detailed quote should cover both materials and labor. Make sure you review all terms before signing a contract.
You should have your HVAC system inspected about twice yearly. After the inspection, your technician will inform you what services are needed. You should also call a technician if you start noticing issues such as strange noises, unusual smells, or leaks. If your system has ductwork, you should have it inspected every few years.
Generally, it's smart to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. This also helps get your system ready for the summer and winter, when it typically sees the most use.
You can save energy during the winter by reducing how much power your HVAC system uses to heat your home. Keep your thermostat as low as you can and don't make drastic temperature changes — only increase or decrease it a few degrees at a time. If you can, try switching to a smart thermostat.
It takes roughly one to three days to have an HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this might take anywhere from a few hours up to two days. This timeline will be determined by the size of your house, the accessibility of your system, and any issues your technician discovers.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. In Kronenwetter, you'll probably be fine with a unit on the lower end of this range. For homes over 1,000 square feet, central air is likely to be more effective for cooling than window units.
For a 2,000-square-foot home, you should also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units). In Kronenwetter, you might need a higher-capacity furnace.
Your HVAC company may provide financing options through a third-party lender, or you may be able to obtain your own loan. It's a good idea to discuss payment options with a financial advisor and your HVAC company to make sure that you're choosing the best option for you.
There are several ways you can make your HVAC system more energy-efficient:
