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 is malfunctioning or suffering from a lot of wear and tear, you may need to hire an HVAC contractor for repairs or replacement. Look for these common signs that your system needs expert attention:
If you're experiencing any of these HVAC issues, we recommend having a technician inspect your system. A local professional can diagnose problems and determine whether fixing or replacing your HVAC unit is the correct solution.
The cost of HVAC installation or maintenance varies depending on the type of unit you have. Common kinds of HVAC units include the following:
The price of HVAC maintenance also varies depending on the kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The prices of some common jobs are as follows:

|---|---|---|
| Split | $1,872-$4,771 | |
| Hybrid Split | $3,793-$6,987 | |
| Heat Pump | $2,937-$29,923 | |
| Packaged Heating and Air | $246-$410 |
Essential HVAC maintenance is important, but can be pricey. Luckily, homeowners can take steps to reduce wear and tear on their system and lower future maintenance needs.

Knowing what to look for in an HVAC company is important for a successful project. Partnering with an experienced, licensed contractor can give you peace of mind and make sure 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 system if possible. Compare the providers' 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 proper licensing and experience. HVAC contractors in all states have federal requirements set by 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 intend 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 Kentucky, HVAC contractors must be licensed by the Department of Housing, Buildings and Construction. An individual can be an apprentice, journeyman, or master contractor. Master contractors are required to have at least two years of experience, need to have general liability insurance, and must participate in ongoing education. You should also check a company's reviews and complaints on sites such as Yelp, Google Reviews, and the Better Business Bureau (BBB). Pick a company with glowing feedback and good customer testimonials.
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 ensure that everything works. When getting a replacement, ask the contractor to explain the new HVAC system energy efficiency, brand, model, features, 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.
Reliable HVAC companies provide warranties for their services. The broader the coverage, the better, so make sure to compare warranties between companies. Choose the one that gives you the most coverage at a fair cost.
Get a written proposal before HVAC work begins. A comprehensive quote includes both materials and labor costs. Make sure you understand and agree to all terms before signing the contract.
Typically, your HVAC system should be inspected twice a year. After that inspection, your technician will tell you what services are required. You should also call a technician if you start to notice any issues, such as strange noises, leaks, or unusual smells. If you have ductwork in your home, it should be serviced every few years.
The best times to have an HVAC inspection are the spring and fall. Technicians are less busy during these times, so it will be easier to get an appointment. This also ensures that your system is 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 work it takes for your HVAC system to maintain your home's temperature. Always 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 installing a smart thermostat.
Generally, whole-system HVAC installation or replacement takes between one and three days. Installing or replacing an air conditioning unit or a furnace may take anywhere from a few hours up to two days. The exact amount of time will vary depending on things like how large your home is, how easily accessible different sections are, and whether your technician discovers any problems.
For a 2,000-square-foot home, you should look for around 2.5 to 5 tons of air conditioning capacity. For a house over 1,000 square feet, central air is likely to 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 several ways you can make your HVAC system more energy-efficient:
