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 having issues or getting near the end of its lifespan, it likely needs servicing or replacement from an HVAC company. Look for these signs your system needs service:
If you notice any of the above, have a local HVAC technician inspect your system. They can pinpoint problems and let you know whether repair or full HVAC replacement is the best course of action.
The cost of HVAC installation or maintenance will vary depending on the kind of unit you have. Common kinds of HVAC units include the following:
HVAC maintenance prices differ based on the specific services needed. HVAC systems can be complicated and potentially require a number of services. Price ranges for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,832-$4,669 | |
| Hybrid Split | $3,711-$6,837 | |
| Heat Pump | $2,874-$29,282 | |
| Packaged Heating and Air | $240-$401 |
Taking care of necessary HVAC repairs and replacements when needed is crucial, but can be costly. Luckily, there are steps you can take to minimize wear and tear over time on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $60-$160 | |
| Condensor Cleaning | $1,202-$3,607 | |
| Thermostat Repair | $80-$200 | |
| Ductwork Cleaning | $385-$962 |
Knowing what to look for in an HVAC company is crucial for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and ensure your system provides reliable air conditioning and heating for your home.
Contact at least three HVAC companies for quotes. Describe the issues and have specialists visit to inspect your HVAC system if possible. Compare the providers' explanations, solutions, estimated costs, timeframes, and warranties. Avoid providers that pressure you or demand payment upfront.
It's important to choose an HVAC company that employs technicians with the proper qualifications and expertise. HVAC contractors in all states have federal requirements from the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, an individual must pass an exam (the specific exam depends on the kind of equipment they plan 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.
In Ohio, HVAC contractors are licensed by the Ohio Construction Industry Licensing Board. To obtain a license, contractors need to have at least five years of experience, carry a minimum amount of contractor liability coverage, and pass an exam. Specific jurisdictions may have additional requirements. You should also look at a company's reviews and complaints on sites such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with great feedback and stories of satisfied customers.
Make sure you know the details of your project before it begins. For HVAC repairs, have your provider specify which parts need replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. When replacing your HVAC system, ask the contractor to provide details on the new brand, features, energy efficiency, model, and estimated installation time. Before signing a contract, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.
Trustworthy HVAC companies stand behind their services with warranties. Look at warranties from different companies, keeping in mind that broader coverage is better. Look for the provider that offers the most coverage for a fair price.
Get written quotes before beginning HVAC work. The quote should cover costs for both materials and labor. Review all terms carefully before signing.
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 an inspection if you notice any new 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 during the spring and fall. Technicians are generally 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, which is when it normally 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 is comfortable, and avoid making drastic changes — adjust it only a few degrees at a time. You could also consider purchasing a smart thermostat.
It takes between one and three days to have an HVAC system installed or replaced. If you need just a furnace or a single air conditioning unit, this can take anywhere from a few hours up to two days. This timeline will be influenced 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 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. Generally, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company might have financing options via a third-party lender, or you might choose to obtain your own loan. It's smart to discuss payment options with a financial advisor and your HVAC company to make sure that you're choosing the best option for you.
There are several ways you can make your HVAC system more energy-efficient:
