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 home's HVAC system is malfunctioning or suffering from a lot of wear and tear, you might need an HVAC contractor for maintenance or replacement. Look for these common signs that your system needs professional attention:
If you notice any of these HVAC red flags, your system evaluated. A local company can complete an inspection, identify problems, and advise you whether you should repair or replace your HVAC unit.
The cost of HVAC installation or maintenance changes depending on the kind of unit you have. Common kinds of HVAC units include the following:
HVAC maintenance prices differ depending on what services are needed. HVAC systems are complex and may require different kinds of maintenance. Costs for some common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,866-$4,758 | |
| Hybrid Split | $3,782-$6,967 | |
| Heat Pump | $2,928-$29,836 | |
| Packaged Heating and Air | $245-$408 |
It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Thankfully, there are steps you can take to reduce wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $61-$163 | |
| Condensor Cleaning | $1,225-$3,675 | |
| Thermostat Repair | $82-$204 | |

Knowing what to look for in an HVAC company is crucial for a successful project. Look for an experienced, licensed contractor that can offer you peace of mind and ensure your system provides reliable air conditioning and heating for your home.
Request estimates from three or more HVAC contractors. Describe your issues and ask if specialists can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid companies that pressure you or demand payment before work.
Choose an HVAC company with well-trained technicians who have appropriate 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, a contractor must pass an exam (the type of exam depends on what 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.
Typically, all Montana contractors are required to register with the Department of Labor and Industry. Independent contractors can apply for exemption. All companies with employees must provide proof of workers' compensation insurance. You should also read reviews and complaints on sites like the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with positive reviews and reports of good customer experiences.
Always make sure you understand the details of a planned project. For HVAC repairs, your provider should list which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are done to verify that it’s working properly. When replacing your HVAC system, request that the installation company describe the new estimated installation time, energy efficiency, features, model, and brand. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.
Trustworthy HVAC companies provide warranties for their services. Broader coverage is better, so make sure to review warranties between providers. Choose the one that offers the best coverage at a reasonable cost.
Get a written proposal before HVAC work starts. A comprehensive quote includes both labor and material costs. Make sure you understand and accept all terms before signing the contract.
Normally, you should have your HVAC system inspected twice a year. After an inspection, your HVAC technician will tell you what services are required. You should also have your system inspected and serviced if you start to notice any issues, such as leaks, strange noises, or unusual smells. If your home has ductwork, it should be serviced every few years.
The best times of the year to have an HVAC inspection are the spring and fall. Technicians tend to be less busy during these times, which makes it easier to get an appointment. This also ensures that your system is ready for the summer and winter, the times of the year when it gets the most use.
You can save energy throughout the year by making it easier for your HVAC system to maintain the temperature of your home. Always keep your thermostat as close to the outside temperature as possible, and avoid making drastic changes — adjust it only a few degrees at a time. You might also consider getting a smart thermostat.
Generally, whole-system HVAC installation or replacement takes between one and three days. Installing or replacing an air conditioning unit or a furnace can take as little as half a day or as much as two days. The exact amount of time will vary depending on factors like the size of your home, how easily accessible different parts of the system are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. If your home is larger than 1,000 square feet, central air is likely to be more effective than window units for cooling.
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).
Usually, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer financing, you might consider taking out a loan on your own. Be sure to speak with your HVAC company and a financial advisor to learn what options are available to you and appropriate for your situation.
