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 professional attention from a technician who can make fixes or install a new unit. Watch out for these common signs that your HVAC needs service:
Arrange an inspection if you notice any of these issues. A local technician can assess your system, detect problems, and decide whether you need to fix or replace your HVAC.
Your HVAC installation or maintenance cost changes depending on the type of unit. Common HVAC unit varieties include the following:
HVAC maintenance costs differ depending on what services are needed. HVAC systems are complicated and can require different kinds of maintenance. Costs for common services are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,758-$4,482 | |
| Hybrid Split | $3,562-$6,563 | |
| Heat Pump | $2,758-$28,107 | |
| Packaged Heating and Air | $231-$385 |
Fixing your HVAC by repairing or replacing parts when needed is important, but can be expensive. Luckily, there are actions you can take to reduce gradual wear and tear on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $58-$154 | |
| Condensor Cleaning | $1,154-$3,462 | |
| Thermostat Repair | $77-$192 | |
| Ductwork Cleaning | $369-$923 |
Knowing the right things to look for in an HVAC company is key for a smooth repair or installation. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent coolig and heating year-round.
Contact at least three HVAC providers for quotes. Explain your issues and schedule an in-person inspection if possible. Compare providers' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand upfront payment.
Choose an HVAC company with well-trained technicians who have proper licensing and experience. In all states, HVAC contractors have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors must pass an exam (the specific exam depends on the kind of equipment they intend 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 at the state level.
There are no specific licensing requirements for HVAC contractors in Nebraska. However, all contractors in the state are required to register with the Nebraska Department of Labor, and any companies that have employees must also have workers' compensation insurance. Your city or municipality might have additional requirements, so always be sure to check with your local government before signing a contract. You should also look at reviews and complaints on sites like the Better Business Bureau (BBB), Google Reviews, and Yelp. Pick a company with glowing reviews and reports of good customer experiences.
Always make sure you understand the details of any project. For HVAC repairs, your provider should specify which parts require replacement and why. Confirm that your technician will clean and test the full system after repairs are completed to ensure that it’s working properly. When replacing your HVAC system, ask the contractor to describe the new brand, energy efficiency, estimated installation time, model, and features. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.
Reliable HVAC companies provide warranties for their work. Broader coverage is better, so make sure to review warranties between companies. Choose the one that provides the most comprehensive coverage at a fair cost.
Always get HVAC bids in writing before work begins. A detailed quote covers costs for both labor and materials. Confirm that you understand all terms before signing the contract.
Generally, you should have your HVAC system inspected twice a year. After that inspection, your HVAC technician will tell you what, if any, services are required. You should also call a technician if you notice any new issues, such as strange noises, leaks, or unusual smells. If you have ductwork in your home, it should be serviced every few years.
The best times to have an HVAC inspection are during the spring and fall. Technicians are less busy during these times, which makes it easier to get an appointment. 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 the temperature of your home. During all seasons, keep your thermostat as close to the outside temperature as possible, and try to adjust it only a few degrees at a time. You may also consider a smart thermostat.
It takes around one to three days to have an HVAC system installed or replaced. If you only need a furnace or a single air conditioning unit, this might take between half a day and two days. This timeline can be affected by the size of your house, how easily accessible your system is, and any new issues your technician runs into.
For a 2,000-square-foot home, you'll want 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 look for an air conditioning unit with around 2.5 to 5 tons of capacity. Usually, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Normally, HVAC financing is provided by a third-party lender. If your HVAC company doesn't offer these options, you could consider taking out a loan on your own. Be sure to speak with your HVAC company and a financial advisor to find out what options are available and appropriate for your situation.
There are several ways you can make your HVAC system more energy-efficient:
