If your home's HVAC system is malfunctioning or suffering from a lot of wear and tear, you might need an HVAC contractor for repairs or replacement. Watch for these common indicators that your system requires professional attention:
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 required.
Your HVAC installation or maintenance cost fluctuates depending on the type of unit. Common HVAC unit varieties include the following:
HVAC expenses vary based on the work needed. HVAC systems are complex and may need multiple types of maintenance. Costs for common jobs are as follows:

Hybrid Split | $3,905-$7,194 | |
Heat Pump | $3,024-$30,809 | |
Packaged Heating and Air | $253-$422 |
It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Luckily, there are some steps you can take to slow the wear and tear on your system.
Service | Cost | |
---|---|---|
Filter Replacement | $63-$169 | |

Finding the right HVAC company is crucial for a smooth installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Contact at least three HVAC companies for quotes. Describe the issues and have technicians visit to inspect your HVAC system if possible. Compare the companies' explanations, solutions, estimated costs, timeframes, and warranties. Avoid contractors that pressure you or demand payment upfront.
When selecting an HVAC company, choose one with technicians that have the right 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 mandatory for all contractors who "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 on a state-by-state basis.
HVAC contractors in Iowa are required to be licensed by the Iowa Plumbing and Mechanical Systems Board and registered with the Iowa Division of Labor. Contractors must be both bonded and insured. Licenses are available under the classifications of apprentice, journeyperson, or master; apprentices and journeypersons must be supervised by a licensed master. You should also read reviews and complaints on sites like the Better Business Bureau (BBB), Yelp, and Google Reviews. Pick a company with glowing reviews and testimonials about good customer experiences.
Always make sure you know the details of a planned project. For HVAC repairs, your provider should detail which parts need replacement and why. Confirm that your technician will clean and test the system after repairs are done to verify that it’s working properly. When replacing your HVAC, have the contractor explain the new features, brand, energy efficiency, estimated installation time, and model. Before signing paperwork, be sure you understand the process your provider will use to size the new HVAC system appropriately for your home and what the price will be.
Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Review warranty details between providers and pick the one that offers the best protection within your budget.
Get a written quote before HVAC work starts. A comprehensive quote includes both materials and labor costs. Make sure you understand and accept all terms before signing the contract.
You should have your HVAC system inspected twice annually. Following an inspection, your technician will tell you what services are needed. You should also call a technician if you notice new issues such as strange noises, unusual smells, or leaks. If your system has ductwork, it should be inspected every few years.
Normally, it's a good idea 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 probably 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 is comfortable, and try to adjust it only a few degrees at a time. You might also consider purchasing a smart thermostat.
Generally, HVAC installation or replacement takes between one and three days for the entire system. 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 how large your home is, how easily accessible different parts of the system are, and whether your technician runs into any problems.
For a 2,000-square-foot home, look for a furnace that's between 50,000 and 80,000 BTUs (British thermal units).
For a 2,000-square-foot home, you'll also want to purchase an air conditioning unit with around 2.5 to 5 tons of capacity. Typically, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Usually, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer these options, you might consider taking out your own loan. Be sure to speak with your HVAC company and a financial advisor to find out what options are available to you and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
