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:
An HVAC system that's malfunctioning or past its lifespan likely needs professional attention for repairs or replacement. Watch for these indicators that your system needs service:
If you're experiencing any of these HVAC issues, you should have a technician inspect your system. A local professional can detect problems and let you know whether whether repairing or getting a new HVAC unit is the best solution.
The cost of HVAC installation or maintenance varies depending on the type of unit you have. Common kinds of HVAC units include the following:
HVAC maintenance costs differ depending on what services are needed. HVAC systems are complex and may require different kinds of maintenance. Fees for common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,855-$4,728 | |
| Hybrid Split | $3,758-$6,923 | |
| Heat Pump | $2,910-$29,649 | |
| Packaged Heating and Air | $243-$406 |
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-$162 | |
| Condensor Cleaning | $1,217-$3,652 | |
| Thermostat Repair | $81-$203 | |
| Ductwork Cleaning | $390-$974 |
Knowing the indicators of a good HVAC company is important. A properly licensed contractor with the right experience will give you confidence that they can maintain your HVAC system properly, providing you with effective air conditioning and heating in your home.
Contact at least three HVAC providers for quotes. Explain the issues and have specialists visit to inspect your system if possible. Compare the providers' explanations, solutions, estimated costs, warranties, and timeframes. Avoid contractors that pressure you or demand payment upfront.
It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. HVAC contractors in all states have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific 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 on a state-by-state basis.
Normally, all Montana contractors must 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. Always check a company's reviews and complaints with organizations such as the Better Business Bureau (BBB), Google Reviews, and Yelp. You'll want to select a provider with glowing reviews and stories of positive service experiences.
Make sure you know the details of any project before starting. For HVAC repairs, have your provider list which parts need replacement and why. Confirm that your technician will clean and test the entire system after the repair to ensure that everything works. When replacing your HVAC system, ask the contractor to provide details on the new estimated installation time, energy efficiency, features, model, and brand. 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.
Trustworthy HVAC companies back their services with warranties. Compare warranties from different companies, keeping in mind that more comprehensive coverage is better. Look for the company that provides the most coverage for a reasonable price.
Get written quotes before starting HVAC work. The quote should include costs for both labor and materials. Review all terms carefully before signing.
You should have your HVAC system inspected twice annually. At the time of the inspection, your technician will inform you what services are needed. You should also have your system inspected if you notice new issues such as strange noises, leaks, or unusual smells. If your home has ductwork, it should be inspected every few years.
Generally, it's smart to schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps make sure your system is prepared for the summer and winter, when it likely 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 is comfortable and avoid making drastic changes in the temperature — increase or decrease it a few degrees at a time. If you're able to, try switching to a smart thermostat.
Generally, HVAC installation or replacement takes between one and three days for the entire system. Installing or replacing an air conditioning unit or a furnace may take anywhere from a few hours up to two days. The exact amount of time will depend on factors like how large your home is, how easily accessible different areas are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you should look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Missoula, you'll likely look for a furnace on the higher end of (or even above) this range.
For a 2,000-square-foot home, you'll also want an air conditioning unit with between 2.5 and 5 tons of capacity. In Missoula, a unit with a lower capacity may be sufficient. Generally, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
There are a number of ways you can make your HVAC system more energy-efficient:
