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 old likely needs professional attention for repairs or replacement. Watch for these indicators that your system needs service:
If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can pinpoint problems and let you know whether repair or full HVAC replacement is the better solution.
The price of HVAC installation or maintenance changes depending on the kind of unit you have. Common kinds of HVAC units include the following:
The cost of HVAC maintenance also varies depending on what kind of work you're having done. HVAC systems are complex and can require different kinds of maintenance. The prices of some common jobs are as follows:
| HVAC Unit Type | Cost | |
|---|---|---|
| Split | $1,817-$4,632 | |
| Hybrid Split | $3,682-$6,784 | |
| Heat Pump | $2,851-$29,051 | |
| Packaged Heating and Air | $239-$398 |
HVAC upkeep is important, but can be expensive. Fortunately, there are steps homeowners can take to reduce wear and tear on their system and lower future maintenance needs.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $60-$159 | |
| Condensor Cleaning | $1,193-$3,579 | |
| Thermostat Repair | $80-$199 | |
| Ductwork Cleaning | $382-$954 |
It's important to know what makes a good HVAC company. A properly licensed contractor with the right experience will give you confidence that they can fix your system, providing you with effective heating and cooling for your home.
Get quotes from at least three HVAC companies. Describe your issues and ask if specialists can inspect your system in person. Compare each company's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid contractors that pressure you or demand payment before work.
Choose an HVAC company with highly trained technicians who have proper licensing and experience. In all states, HVAC contractors have federal requirements set by the Environmental Protection Agency (EPA). To obtain the EPA Section 608 Technician Certification, contractors 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 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, possess a minimum amount of contractor liability coverage, and pass an exam. Specific jurisdictions may have additional requirements. Always check a provider's reviews and complaints with organizations such as Yelp, Google Reviews, and the Better Business Bureau (BBB). Look for a a provider with positive reviews and a history of good customer service.
Make sure you know the details of your project before it begins. If HVAC repairs are required, have your provider specify which parts need replacement and why. Confirm that your technician will clean and test the system after the repair to verify that everything works. When replacing your HVAC, ask your contractor to provide details on the new estimated installation time, energy efficiency, brand, features, and model. 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.
A trustworthy HVAC company will stand behind its repair services and equipment installations with a warranty. The longer and more comprehensive the coverage terms, the better. Carefully review warranty terms for each contractor and choose the provider that offers the most protection within your budget.
Always get quotes for HVAC service in writing before work begins. A detailed quote should cover both labor and materials. Make sure you understand all terms before signing a contract.
You should have your HVAC system inspected 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, strange noises, or unusual smells. If your system has ductwork, it should be inspected every few years.
Usually, it's best to schedule inspections in the spring and fall, as technicians tend to be less busy at these times. This also helps get your system ready for the summer and winter, when it likely sees the most use.
You can save energy throughout the year by making it easier for your HVAC system to maintain the temperature of your home. 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 a time. You might also consider a smart thermostat.
It takes around one to three days to have an HVAC system installed or replaced. If you need just a furnace or a single air conditioning unit, this may take between half a day and two days. This timeline will be affected by the size of your house, how easily accessible your system is, and any new issues your technician discovers.
For a 2,000-square-foot home, you need around 2.5 to 5 tons of air conditioning capacity. For homes over 1,000 square feet, central air will be more effective than window units for cooling.
For a 2,000-square-foot home, you should also look for a furnace that is between 50,000 and 80,000 BTUs (British thermal units).
There are a number of ways you can make your HVAC system more energy-efficient:
