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 home's HVAC system isn't working correctly or nearing the end of its lifespan, you may need to hire an HVAC contractor for repairs or replacement. Look for these common indicators that your system requires expert attention:
If you're experiencing any of these HVAC issues, have a technician inspect your system. A local professional can identify problems and let you know whether whether fixing or replacing your HVAC unit is the correct solution.
The price of HVAC installation or maintenance will differ depending on the type of unit you have. Common types of HVAC units include the following:
HVAC costs differ based on the work needed. HVAC systems are complicated and may need a number of types of maintenance. Prices for common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,863-$4,750 | |
| Hybrid Split | $3,775-$6,955 | |
| Heat Pump | $2,923-$29,786 | |
| Packaged Heating and Air | $245-$408 |
It’s important to complete repairs or full-system HVAC replacements as needed, though they can be expensive. The good news is that homeowners have ways to reduce gradual wear and tear and reduce the frequency of breakdowns.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $61-$163 | |
| Condensor Cleaning | $1,223-$3,669 | |
| Thermostat Repair | $82-$204 | |
| Ductwork Cleaning | $391-$978 |
Knowing what to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor can offer you peace of mind and make sure your system provides reliable heating and air conditioning for your home.
Contact at least three HVAC providers for quotes. Explain the issues and have specialists visit to inspect your system if possible. Compare the contractors' explanations, solutions, estimated costs, warranties, and timeframes. Avoid contractors that pressure you or demand payment upfront.
Choose an HVAC company with well-trained technicians who have appropriate 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, a contractor must pass an exam (the type of 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 on a state-by-state basis.
HVAC contractors in Ohio are licensed by the Ohio Construction Industry Licensing Board. To obtain a license, contractors need to have at least five years of experience, have a minimum amount of contractor liability coverage, and pass an exam. Your local jurisdiction may have additional requirements. Reviewing feedback on Google Reviews, Yelp, the Better Business Bureau (BBB), and similar sites can help your decision as well. Choose a provider with stellar reviews and stories of positive customer experiences.
It’s important to know what the work process will look like. For HVAC repairs, the company should list the specific parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to make sure everything is operating properly. When replacing your HVAC, have the contractor explain the new features, energy efficiency, estimated installation time, model, and brand. Before signing paperwork, make 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.
Trustworthy HVAC companies stand behind their work with warranties. Look at warranties from different companies, while remembering that broader coverage is better. Look for the provider that offers the most coverage for a fair price.
Get a written proposal before HVAC work starts. A full quote includes both labor and material costs. Make sure you understand and agree to all terms before signing the contract.
You should have your HVAC system inspected twice annually. After the inspection, your technician will tell you what services are needed. You should also schedule an inspection if you start noticing issues such as strange noises, leaks, or unusual smells. If your home has ductwork, it should be inspected every few years.
Normally, it's best to have your HVAC system inspected 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 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 you can, and try to adjust it only a few degrees at a time. You may also consider getting a smart thermostat.
It takes between one and three days to have an HVAC system installed or replaced. If you need just an air conditioning unit or a furnace, this can take anywhere from a few hours up to two days. This timeline will be influenced by the size of your home, how easily accessible your system is, and any new issues your technician discovers.
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 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.
Your HVAC company might provide financing options via a third-party lender, or you might choose to obtain your own loan. It's a good idea to discuss payment options with your HVAC company and a financial advisor 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:
