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:
A malfunctioning or aging HVAC system probably needs attention from a professional who can make fixes or install a new unit. Keep an eye out for these common indicators that your HVAC needs service:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can pinpoint problems and let you know whether repair or full HVAC replacement is needed.
HVAC installation or maintenance costs change depending on your system. Common HVAC unit types include the following:
The price of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complex and can require different kinds of maintenance. The cost of some common repairs is as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $2,003-$5,106 | |
| Hybrid Split | $4,058-$7,477 | |
| Heat Pump | $3,142-$32,020 | |
| Packaged Heating and Air | $263-$438 |
Essential HVAC maintenance is important, but can be pricey. Luckily, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $66-$175 | |
| Condensor Cleaning | $1,315-$3,944 | |

It's important to know what makes a good HVAC company. Working with a contractor that's properly licensed and highly experienced will give you confidence that they can maintain your HVAC system properly, providing you with effective heating and cooling for your home.
Contact at least three HVAC companies for quotes. Describe the issues and have specialists visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, warranties, and timeframes. Avoid contractors that pressure you or demand payment upfront.
When hiring an HVAC company, choose one with technicians that have the appropriate training, licenses, and experience. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians who "maintain, service, repair or dispose of equipment that could release refrigerants into the atmosphere." An individual 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 at the state level.
There are no state-level licensing requirements for HVAC technicians in Colorado; however, anyone who runs an HVAC business is required to have a Colorado business license, as well as insurance. You should check with your municipal government to learn if there are any local licensing requirements for HVAC contractors. Any contractors who do plumbing or electrical work in addition to HVAC work must be registered with the State Plumbing Board or the Colorado Electrical Board, respectively. You should also check reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a company with glowing reviews and testimonials about fantastic customer experiences.
Always make sure you know the details of a planned project. For HVAC repairs, your provider should specify which parts need replacement and why. Confirm that your technician will clean and test your system after repairs are done to ensure that it’s working properly. For replacement, ask the contractor to explain the new HVAC system estimated installation time, features, model, brand, and energy efficiency. Before starting the project, you should understand how your provider will size the system appropriately for your home and the price you'll pay.
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.
Always get HVAC bids in writing before work begins. A detailed quote covers costs for both materials and labor. Confirm that you agree to 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, if any, services are required. You should also have an inspection if you start to notice any issues, such as leaks, unusual smells, or strange noises. If your home has ductwork, it should be serviced every few years.
The best times of the year to have your HVAC system inspected 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 reducing the amount of work it takes 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 could also consider installing a smart thermostat.
Generally, whole-system HVAC installation or replacement takes between one and three days. Installing or replacing a furnace or air conditioning unit may take anywhere from a few hours up to two days. The exact amount of time will depend on factors like the size of your home, how easily accessible different parts of the system are, and whether your technician runs into any problems.
For a 2,000-square-foot home, try to purchase a furnace that's between 50,000 and 80,000 BTUs (British thermal units). In Lafayette, you'll probably want a furnace on the higher end of (or even above) this range.
For a 2,000-square-foot home, you'll also want to look for an air conditioning unit with between 2.5 and 5 tons of capacity. Usually, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
There are several ways you can make your HVAC system more energy-efficient:
