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. Watch for these common signs that your system requires expert attention:
If you see any of these HVAC issues, have a technician inspect your system. A local professional can diagnose problems and decide whether repairing or getting a new HVAC unit is the best solution.
What you spend on HVAC installation or maintenance varies based on your system style. Common HVAC unit styles include the following:
HVAC maintenance costs vary depending on the particular service needed. HVAC systems are complex and might require different maintenance services. Prices for some common services are as follows:
| HVAC Unit Type | Cost | |

| Hybrid Split | $3,888-$7,164 | |
| Heat Pump | $3,011-$30,679 | |

Repairing or replacing your HVAC system when needed is important, but can be costly. Thankfully, there are actions you can take to minimize wear and tear over time on your system.
| Service | Cost | |
|---|---|---|
| Filter Replacement | $63-$168 | |
| Condensor Cleaning | $1,260-$3,779 | |

Knowing what makes a trustworthy HVAC company is key for an easy installation or repair. An experienced, credentialed HVAC contractor gives you confidence your system can provide reliable heating and air conditioning year-round.
Request estimates from three or more HVAC contractors. Explain your issues and ask if specialists can inspect your system in person. Compare each contractor's diagnoses, recommended solutions, estimated cost, warranties, and timeline. Avoid providers that pressure you or demand payment before work.
Choose an HVAC company with skilled technicians who have proper 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, an individual 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 Kentucky must be licensed by the Department of Housing, Buildings and Construction. An individual can be an apprentice, journeyman, or master contractor. Master contractors must have at least two years of experience, need to have general liability insurance, and must participate in ongoing education. Always check a company's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. You want to hire a provider with glowing reviews and stories of positive service experiences.
Make sure you know the details of your project before it begins. When getting HVAC repairs, have your provider list which parts require replacement and why. Get confirmation that your technician will clean and test the system after the repair to ensure that everything works. When replacing your HVAC, have the provider describe the new brand, model, estimated installation time, features, and energy efficiency. Before signing a contract, ask about the process your provider will use to properly size the new system for your home and how much it will cost.
A trustworthy HVAC company will stand behind its repair services and equipment installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully review warranty terms for each contractor and choose the provider that offers the greatest protection within your budget.
Always get HVAC quotes in writing before work begins. A thorough quote will cover costs for both materials and labor. Make sure that you agree to all terms before signing the contract.
You should have your HVAC system inspected approximately twice annually. At the time of the inspection, your technician will tell you if any services are needed. You should also call a technician if you start noticing issues such as strange noises, unusual smells, or leaks. If your system has ductwork, you should have it inspected every few years.
Normally, it's best to have your HVAC system inspected in the spring and fall, as these times tend to be less busy. 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. Always keep your thermostat as close to the outside temperature as is comfortable, and avoid making drastic changes — adjust it only a few degrees at a time. You might also consider a smart thermostat.
It takes between one and three days to have your 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 can be affected 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 want 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. 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 offer financing options through a third-party lender, or you might be able to obtain a loan on your own. 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 a number of ways you can make your HVAC system more energy-efficient:
