If your home's HVAC system is malfunctioning or suffering from a lot of wear and tear, you may need to hire an HVAC contractor for repairs or replacement. Look for these common indicators that your system needs expert attention:
These HVAC red flags indicate that you should have your system evaluated. A local company can complete an inspection, identify problems, and recommend repairing or replacing your HVAC unit.
What you pay for HVAC installation or maintenance depends on your system type. Common HVAC unit styles include the following:
HVAC costs differ based on the work needed. HVAC systems are complicated and may need several types of maintenance. Prices for common jobs are 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 |
HVAC system repairs and replacements are important, but can be expensive. Thankfully, 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 | |
| Thermostat Repair | $88-$219 | |

Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. Picking an established business with certified technicians gives you assurance your HVAC system will deliver consistent heating and cooling year-round.
Contact at least three HVAC companies for quotes. Describe the issues and have specialists visit to inspect your system if possible. Compare the providers' explanations, solutions, estimated costs, warranties, and timeframes. Avoid companies that pressure you or demand payment upfront.
When selecting an HVAC company, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states need to 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.
The state of Colorado doesn't have state-level HVAC contractor licensing requirements; however, anyone who runs an HVAC business is required to have a Colorado business license, as well as insurance. You may want to check with your municipal government to determine if there are local licensing requirements for HVAC contractors. Any contractors who do plumbing or electrical work in addition to HVAC work must register with the State Plumbing Board or the Colorado Electrical Board, respectively. You should also look at reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Choose a company with positive reviews and reports of great customer experiences.
It’s important to understand what the work process is going to look like. For HVAC repairs, the company should detail the specific parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to guarantee everything is working correctly. When getting a replacement, ask your contractor to explain the new HVAC system brand, estimated installation time, energy efficiency, features, and model. Before starting the project, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.
Trustworthy HVAC companies provide warranties for their work. The broader the coverage, the better, so make sure to compare warranties between providers. Choose the one that offers the best coverage at a fair cost.
Always get HVAC estimates in writing before work begins. A thorough quote will cover costs for both labor and materials. Ensure that you agree to all terms before signing the contract.
You should have your HVAC system inspected approximately twice a year. At the time of the inspection, your technician will inform you what services are required. You should also call a technician if you notice new issues such as strange noises, leaks, or unusual smells. If your system has ductwork, you should have it inspected every few years.
Usually, you should have your HVAC system inspected in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it typically sees the most use.
You can save energy throughout the year by reducing the amount of power your HVAC system uses to maintain your home's temperature. During all seasons, 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 getting a smart thermostat.
It takes around one to three days to have your HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this may take anywhere from a few hours up to two days. This timeline can be affected by the size of your house, how easily accessible your system is, and any issues your technician uncovers.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. For a house over 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). In Lakewood, you might need a higher-capacity furnace.
Typically, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer these options, you could consider taking out your own loan. Be sure to speak with a financial advisor and your HVAC company to learn what options are available and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
