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:
If your HVAC system is broken or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Look for these indicators your system 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 determine whether repair or full HVAC replacement is required.
What you spend on HVAC installation or maintenance depends on your system style. Common HVAC unit styles include the following:
HVAC maintenance costs differ based on the specific services required. HVAC systems can be complex and potentially require several different services. Fees for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,743-$4,444 | |
| Hybrid Split | $3,532-$6,508 | |
| Heat Pump | $2,735-$27,869 | |
| Packaged Heating and Air | $229-$381 |
HVAC system repairs and replacements are important, but can be expensive. Luckily, there are steps homeowners can take to reduce wear and tear on their system and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $57-$153 | |
| Condensor Cleaning | $1,144-$3,433 | |
| Thermostat Repair | $76-$191 | |
| Ductwork Cleaning | $366-$916 |
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 your issues and schedule an in-person inspection if possible. Compare contractors' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand upfront payment.
When hiring an HVAC provider, choose one with technicians that have the appropriate 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 the type 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.
There are no state-level licensing requirements for HVAC contractors in Indiana; however, most cities and municipalities have their own regulations. Be sure that you check with your local government and verify the business license of any company you hire. Reviewing feedback on the Better Business Bureau (BBB), Yelp, Google Reviews, and similar sites can help your decision as well. Choose a company with stellar reviews and reports of positive customer experiences.
Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to explain which parts require replacement and why. Confirm that your technician will clean and test the system after finishing the work to guarantee proper operation. When replacing your HVAC system, request that the installation company describe the new features, energy efficiency, brand, model, and estimated installation time. Before signing a contract, ask how your provider plans to accurately size the unit for your home and how much it will cost.
Good HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Compare warranty details between companies and pick the one that provides the best protection for a fair price.
Always get HVAC bids in writing before work begins. A detailed 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. After the inspection, your technician will inform you what services are needed. You should also schedule an inspection if you notice new issues such as unusual smells, leaks, or strange noises. If your system has ductwork, it should be inspected every few years.
Generally, you should have your HVAC system inspected in the spring and fall, as these times tend to be less busy. 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 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 you can, and try to adjust it only a few degrees at once. You might also consider a smart thermostat.
Generally, whole-system HVAC installation or replacement takes one to three days. 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 vary depending on factors like how large your home is, how easily accessible different areas are, and whether your technician runs into 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).
For a 2,000-square-foot home, you'll also want an air conditioning unit with around 2.5 to 5 tons of capacity. In general, if your home is over 1,000 square feet, central air will be more effective than window air conditioning units.
Normally, HVAC financing is offered through a third-party lender. If your HVAC company doesn't offer financing, you may consider taking out a loan on your own. Be sure to talk to your HVAC company and a financial advisor to learn what options are available to you and appropriate for your situation.
There are a number of ways you can make your HVAC system more energy-efficient:
