10 Best HVAC Companies in McDonough, GA

Signs You May Need HVAC Repair or Replacement

An HVAC system that's not working properly or past its lifespan likely needs professional attention for repairs or replacement. Watch for these signs that your system needs service:

• Frequent breakdowns and need for repairs
• Strange noises when the system turns on
• Higher than normal energy bills
• Poor air circulation or uneven heating/cooling
• Thermostat malfunctions or temperature control issues
• Corrosion, rust, or cracking
• Refrigerant leaks
• An HVAC system that's over 15 years old

If you notice any of these HVAC issues, we recommend having a technician inspect your system. A local professional can detect problems and decide whether repairing or getting a new HVAC unit is the best solution.

Cost of HVAC Installation and Maintenance in McDonough

HVAC installation or maintenance prices vary depending on your system. Common HVAC unit types include the following:

• Split or mini-split: If your home lacks the ductwork for central heating and cooling, you likely have a split or mini-split system instead. Split HVAC systems have indoor units in each room to control temperature. These connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the advantage of being able to utilize energy from either electric or gas sources.
• Heat pump: Heat pumps work by circulating hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are more suited to more moderate climates. They may not be as effective during McDonough's hot summers.
• Packaged heating and air: Packaged HVAC systems are a smart choice for smaller homes. These systems have a single heating and cooling unit, normally located in an attic or basement. They're compact, energy-efficient, and easy to maintain.

HVAC maintenance costs vary depending on the particular service needed. HVAC systems are complicated and may require different kinds of maintenance. Fees for some common services are as follows:

Ways to Save Money on HVAC Costs

It’s important to complete repairs or full-system HVAC 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.

• Change the position of your blinds seasonally. Leaving your blinds open during the winter helps warm your home with passive solar heating. Closing the blinds during the summer helps prevent the heat from getting inside. Doing both helps minimize the demand on your HVAC system.
• Change filters regularly. Replacing or cleaning your air filters every 30–90 days helps air flow smoothly through your system. Also try to keep debris away from the external sections of your HVAC system as much as possible.
• Monitor for potential problems. Keeping an eye out for problems, for instance by routinely checking your thermostat and energy bills, lets you resolve them before they get out of hand.
• Keep your system clean. Keeping your grills, ductwork, indoor evaporator coil, and condenser fan blades clean helps your system run and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system whenever it begins to look dirty.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy 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.

Compare Multiple Bids

Contact at least three HVAC providers for quotes. Describe the issues and have specialists visit to inspect your HVAC system if possible. Compare the contractors' explanations, solutions, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand payment upfront.

Check Credentials

Look for an HVAC company that employs skilled technicians who have the necessary training and licenses. In all states, HVAC contractors need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all technicians 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 what kind 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.

All HVAC contractors in Georgia must be licensed. They may hold a Class I or Class II license. Class I licenses require four years of experience and limit the type of equipment a contractor can work on. A Class II license requires five years of experience and is unrestricted. You can verify a license on the Secretary of State's website. Always check a company's reviews and complaints with organizations such as Google Reviews, the Better Business Bureau (BBB), and Yelp. You'll want to select a provider with glowing reviews and stories of positive service experiences.

Understand Work Details

Always make sure you know what a company’s process looks like. When HVAC repairs are needed, ask your provider to list which parts require replacement and explain why. Confirm that your technician will clean and test the full system after finishing the work to verify proper operation. When replacing your HVAC, ask the installation company to provide details on the new energy efficiency, estimated installation time, features, model, and brand. Before signing a contract, make sure you understand the process your provider will use to select the correctly sized system for your home and what the cost will be.

Compare Warranties

Reputable HVAC companies stand behind their services with warranties. Compare warranties from different companies, bearing in mind that broader coverage is better. Look for the provider that offers the most coverage for a fair price.

Get Quote in Writing

Always get HVAC bids in writing before work begins. A comprehensive quote will cover costs for both labor and materials. Confirm that you agree to all terms before signing the contract.
