10 Best HVAC Companies in Marietta, GA

Signs You May Need HVAC Repair or Replacement

An HVAC system that's broken or outdated likely needs professional attention for maintenance or replacement. Watch for these signs that your system needs service:

• Odd noises when the system turns on
• Thermostat malfunctions or temperature control issues
• Unusually high energy bills
• Frequent breakdowns and need for repairs
• Uneven heating/cooling or poor air circulation
• Refrigerant leaks
• Rust, cracking, or corrosion
• An HVAC system that's over 15 years old

If you notice any of the above, it's wise to have a local HVAC technician inspect your system. They can identify problems and let you know whether repair or full HVAC replacement is needed.

Cost of HVAC Installation and Maintenance in Marietta

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

• Split or mini-split: If your home's ductwork can't accommodate a central HVAC system, you probably have a split or mini-split system. Split systems have internal units in each room to control temperature; these indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system functions very similarly to a standard split system. It has the advantage of being able to utilize either gas or electricity for power.
• Heat pump: Heat pumps transfer hot and cool air between your home and the outdoors. They don't generate their own heat or AC, so they perform best in moderate climates and may not be as effective during Marietta's hot summers.
• Packaged heating and air: Packaged HVAC systems are a good choice for smaller houses. They have a single heating and cooling unit, normally in an attic or basement. This unit is often space-saving, energy-efficient, and easy to maintain.

The price of HVAC maintenance also depends on the kind of work being done. HVAC systems are complex and may require different kinds of maintenance. The cost of some common repairs is as follows:

Ways to Save Money on HVAC Costs

HVAC system repairs and replacements are important, but can be pricey. Thankfully, there are steps homeowners can take to reduce wear and tear on their HVAC and lower future maintenance needs.

• Change the position of your blinds seasonally. Opening your blinds in winter allows passive solar heat into your house. Closing your blinds in summer blocks some heat from getting indoors. Both of these measures help decrease the work required from your home’s HVAC system.
• Keep your system clean. Keeping your indoor evaporator coil, condenser fan blades, grills, and ductwork clean helps your HVAC system function properly and lowers the risk of mold. The National Air Duct Cleaners Association recommends cleaning your home's HVAC system when you notice it starting to get dirty.
• Change filters regularly. Changing or cleaning your air filters every 30–90 days helps air flow efficiently through your HVAC system. You should also try to prevent dirt and debris from building up around the outside areas of your system.
• Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, lets you resolve them before they get too expensive.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is vital for a successful installation or repair. Hiring an experienced, credentialed HVAC contractor gives you confidence your system can provide consistent heating and air conditioning year-round.

Compare Multiple Bids

Request estimates from three or more HVAC companies. Explain your issues and ask if specialists can inspect your system in person. Review each company's diagnoses, recommended solutions, estimated cost, timeline, and warranties. Avoid companies that pressure you or demand payment before work.

Check Credentials

It's important to choose an HVAC company that employs technicians with the appropriate qualifications and expertise. HVAC contractors in all states 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 what 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.

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. Licenses can be verified on the Secretary of State's website. You should also read reviews and complaints on sites like Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with glowing reviews and reports of fantastic customer experiences.

Understand Work Details

Make sure you understand the details of your project before it begins. For HVAC repairs, have your provider list which parts need 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, ask your installation company to provide details on the new brand, estimated installation time, energy efficiency, features, and model. Before work begins, make sure you understand how your provider will properly size the new unit for your home and what the cost will be.

Compare Warranties

Reputable HVAC companies back their work with warranties. Look at warranties from different companies, remembering that broader coverage is better. Look for the company that offers the most coverage for a reasonable price.

Get Quote in Writing

Get a written quote before HVAC work begins. A full quote includes both labor and material costs. Make sure you understand and agree to all terms before signing the contract.
