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 faulty or getting old, it likely needs servicing or replacement from an HVAC company. Watch for these indicators your system needs service:
If you notice any of these HVAC issues, you should have a technician inspect your system. A local professional can detect problems and determine whether fixing or replacing your HVAC unit is the best solution.
What you spend on HVAC installation or maintenance varies based on your system type. Common HVAC unit styles include the following:
The cost of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The prices of some common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,867-$4,760 | |
| Hybrid Split | $3,783-$6,970 | |
| Heat Pump | $2,930-$29,851 | |
| Packaged Heating and Air | $245-$409 |
Fixing your HVAC by repairing or replacing parts when needed is crucial, but can be expensive. Fortunately, there are actions you can take to minimize wear and tear over time on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $61-$163 | |
| Condensor Cleaning | $1,226-$3,677 | |
| Thermostat Repair | $82-$204 | |
| Ductwork Cleaning | $392-$981 |
Knowing the indicators of a reliable HVAC company is key for a smooth installation or repair. Established providers with certified technicians can offer assurance your HVAC system will deliver consistent coolig and heating year-round.
Get quotes from at least three HVAC contractors. Explain your issues and ask if specialists can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, warranties, and timelines. Avoid companies that pressure you or demand payment before work.
When hiring an HVAC provider, 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." An individual 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.
There are no state-level licensing requirements for HVAC contractors in Indiana; however, most municipalities and cities have their own regulations. Make sure that you check with your local government and verify the business license of any company you hire. Reviewing feedback on Yelp, the Better Business Bureau (BBB), Google Reviews, and similar sites can aid your decision. Choose a company with great reviews and reports of positive experiences from customers.
Make sure you know the details of any project before it begins. If HVAC repairs are required, have your provider detail which parts need replacement and why. Confirm that your technician will clean and test the entire system after the repair to verify that everything works. When replacing your HVAC, ask the provider to explain the new estimated installation time, energy efficiency, model, features, and brand. Before signing paperwork, make sure you understand how your provider will determine the right system size for your home and what the price will be.
Reliable HVAC companies offer warranties on service and equipment installations. The more complete the coverage, the better. Review warranty details between companies and pick the one that provides the best protection for the fairest price.
Always get quotes for HVAC service in writing before work begins. An itemized quote should cover both materials and labor. Make sure you agree to all terms before signing a contract.
Typically, you should have your HVAC system inspected twice a year. After that inspection, your technician will tell you what services are required. You should also have your system inspected and serviced if you start to notice any issues, like strange noises, unusual smells, or leaks. If your home has ductwork, it should be serviced every few years.
The best times to have an HVAC inspection are the spring and fall. Technicians are 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 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 once. You might also consider getting a smart thermostat.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air will usually be more effective than window units for cooling.
For a 2,000-square-foot home, you'll also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).
Typically, HVAC financing is provided by a third-party lender. If your HVAC company doesn't have financing options, you could consider taking out a loan on your own. 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:
