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 not working properly or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signals that your system needs service:
If you notice any of these HVAC issues, have a technician inspect your system. A local professional can identify problems and determine whether repairing or getting a new HVAC unit is the correct solution.
What you spend on HVAC installation or maintenance is determined by your system type. Common HVAC unit styles include the following:
HVAC maintenance costs differ based on the specific services needed. HVAC systems can be complicated and potentially require several different services. Fees for typical jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,630-$4,156 | |
| Hybrid Split | $3,303-$6,085 | |
| Heat Pump | $2,558-$26,061 | |
| Packaged Heating and Air | $214-$357 |
It’s important to make any essential HVAC fixes or 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 | $54-$143 | |
| Condensor Cleaning | $1,070-$3,210 | |
| Thermostat Repair | $71-$178 | |
| Ductwork Cleaning | $342-$856 |
Finding the right HVAC company is crucial for a smooth installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Contact at least three HVAC providers for quotes. Describe your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, warranties, and timeframes. Avoid providers that pressure you or demand upfront payment.
When selecting an HVAC company, choose one with technicians that have the appropriate training, licenses, and experience. HVAC contractors in all states must obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is mandatory 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 the type of equipment they intend to work with) to be certified by the EPA. All other licensing requirements are handled by the state.
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. Specific jurisdictions may have additional requirements. Reviewing feedback on Google Reviews, the Better Business Bureau (BBB), Yelp, and similar sites can assist your decision. Choose a provider with stellar reviews and reports of positive customer experiences.
It’s important to know what the work process is going to look like. For HVAC repairs, the company should explain the exact 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. For replacement, ask your contractor to explain the new HVAC system brand, energy efficiency, features, model, and estimated installation time. Before starting the project, you should understand the process your provider will use to properly size the system for your home and the price you'll pay.
Trustworthy HVAC companies back their services with warranties. Look at warranties from different companies, remembering that more comprehensive coverage is better. Look for the provider that offers the most coverage for a fair price.
Always get HVAC quotes in writing before work begins. A comprehensive quote will cover costs for both materials and labor. Confirm that you agree to all terms before signing the contract.
Generally, your HVAC system should be inspected twice a year. After an 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 you have ductwork in your home, it should be serviced every few years.
The best times to have your HVAC system inspected are during the spring and fall. Technicians tend to be less busy during these times, which makes it easier to get an appointment. This also helps get your system 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 power your HVAC system uses to maintain the temperature of your home. Always keep your thermostat as close to the outside temperature as you can, and avoid making drastic changes — adjust it only a few degrees at a time. You could 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 can take as little as half a day or as much as two days. The exact amount of time will be based on factors like how large your home is, how easily accessible different areas are, and whether your technician discovers any problems.
For a 2,000-square-foot home, try to purchase 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 between 2.5 and 5 tons of capacity. Usually, if your home is larger than 1,000 square feet, central air will be more effective than window air conditioning units.
Your HVAC company may provide financing options through a third-party lender, or you might be able to obtain a loan on your own. It's smart to discuss payment options with your HVAC company and a financial advisor to make sure that you find the best option for you.
There are several ways you can make your HVAC system more energy-efficient:
