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:
An HVAC system that's malfunctioning or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:
Arrange an inspection if you notice any of these problems. A local technician can evaluate your system, detect problems, and determine whether you need repairs or a new HVAC unit.
Your HVAC installation or maintenance cost changes depending on the type of unit. Common HVAC unit types include the following:
The amount you spend on HVAC maintenance also varies depending on the kind of work you're having done. HVAC systems are complicated and might require different kinds of maintenance. The prices of some common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,782-$4,544 | |
| Hybrid Split | $3,612-$6,654 | |
| Heat Pump | $2,797-$28,496 | |
| Packaged Heating and Air | $234-$390 |
It's important to fix or swap out your HVAC components when they become damaged, but it can also be expensive. Luckily, there are steps you can take to reduce wear and tear on your HVAC.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $59-$156 | |
| Condensor Cleaning | $1,170-$3,510 | |
| Thermostat Repair | $78-$195 | |
| Ductwork Cleaning | $374-$936 |
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. Describe the issues and have technicians visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, warranties, and timeframes. Avoid contractors that pressure you or demand payment upfront.
When picking an HVAC provider, choose one with technicians that have the appropriate training, licenses, and experience. In all states, HVAC contractors must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required 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.
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, possess a minimum amount of contractor liability coverage, and pass an exam. Your local jurisdiction may have additional requirements. Reviewing feedback on Yelp, Google Reviews, the Better Business Bureau (BBB), and similar sites can assist your decision as well. Choose a company with stellar reviews and stories of positive experiences from customers.
Always make sure you know what a company’s process is like. When getting HVAC repairs, ask your provider to list which parts require replacement and explain why. Confirm that your technician will clean and test the system after finishing the work to guarantee proper operation. When replacing your HVAC, have the contractor explain the new brand, model, energy efficiency, features, and estimated installation time. Before signing a contract, be sure you understand how your provider will determine the right system size for your home and what the price will be.
Trustworthy HVAC companies stand behind their work with warranties. Compare warranties from different companies, remembering that broader coverage is better. Look for the provider that offers the most coverage for a reasonable price.
Get written bids before beginning any HVAC work. The quote should cover costs for both materials and labor. Review all terms carefully before signing.
You should have your HVAC system inspected approximately twice annually. At the time of the inspection, your technician will inform you what services are required. You should also schedule an inspection if you start noticing issues such as leaks, unusual smells, or strange noises. If your home has ductwork, it should be inspected every few years.
Generally, it's best to schedule inspections 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 typically sees the most use.
You can save energy throughout the year by making it easier for your HVAC system to maintain your home's temperature. 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 installing a smart thermostat.
It takes roughly one to three days to have your HVAC system installed or replaced. If you only need an air conditioning unit or a furnace, this can take between half a day and two days. This timeline will be influenced by the size of your house, how easily accessible your system is, and any issues your technician runs into.
For a 2,000-square-foot home, you'll need between 2.5 and 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air will generally 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).
Your HVAC company may provide financing options via a third-party lender, or you may choose to obtain your own loan. It's smart 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 a number of ways you can make your HVAC system more energy-efficient:
