10 Best HVAC Companies in Kennesaw, GA

Signs You May Need HVAC Repair or Replacement

A faulty or aging HVAC system probably needs professional attention from a technician who can make fixes or install a new unit. Look out for these common signs that your HVAC needs service:

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

If you notice any of the above, 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 Kennesaw

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

• Split or mini-split: If your home's ductwork isn’t suited for a central HVAC system, you likely have a split or mini-split system. Split systems have internal units in each room to regulate temperature; these indoor units all connect to an outdoor unit.
• Hybrid split: A hybrid split HVAC system operates similar to a normal split system, but has the benefit of being able to draw power from either electric or gas sources.
• Heat pump: Heat pumps work by transferring hot and cold air between your home and the outdoors. These systems don't generate heat or air conditioning themselves, and are better for more moderate climates. They may not be as effective during Kennesaw's hot summers.
• Packaged heating and air: Packaged HVAC systems are often a good option for smaller homes. Packaged systems consist of a single heating and cooling unit that's normally located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

HVAC maintenance prices vary based on the work needed. HVAC systems are complicated and may need multiple types of maintenance. Prices for common jobs are as follows:

Ways to Save Money on HVAC Costs

Fixing your HVAC by repairing or replacing parts when needed is crucial, but can be costly. Luckily, there are actions you can take to minimize wear and tear over time on your system.

• Monitor for potential problems. Monitoring your system for issues — for example, by checking your thermostat and energy bills regularly — helps you catch issues before they get too expensive.
• Keep your system clean. Cleaning your ductwork, indoor evaporator coil, condenser fan blades, and grills regularly helps your HVAC system work efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system when it begins to look dirty.
• Change filters regularly. Replacing your air filters or washing them every 30–90 days allows effective air circulation through your system. Also try to keep debris from accumulating on the external parts of your HVAC.
• Change the position of your blinds seasonally. Closing your blinds in the summer blocks some passive solar heat from getting indoors. Opening the blinds in the winter allows this same heat to help warm your home. Both of these measures help lower the work required from your house's HVAC system.

How To Choose a Local HVAC Company

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.

Compare Multiple Bids

Contact at least three HVAC contractors for quotes. Describe your issues and schedule an in-person inspection if possible. Compare companies' diagnoses, suggested repairs, estimated costs, timeframes, and warranties. Avoid companies that pressure you or demand upfront payment.

Check Credentials

It's important to choose an HVAC company that employs technicians with the proper 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, contractors must pass an exam (the type of exam depends on what 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 by the state.

In Georgia, all HVAC contractors must be licensed. They can have either 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. Class II licenses require five years of experience and are unrestricted. You can verify a license on the Secretary of State's website. You should also look at reviews and complaints on sites like Yelp, Google Reviews, and the Better Business Bureau (BBB). Choose a company with positive reviews and testimonials about great customer experiences.

Understand Work Details

Make sure you know the details of your project before it begins. For HVAC repairs, have your provider detail which parts need replacement and why. Get confirmation that your technician will clean and test your system after the repair to ensure that everything works. When getting a replacement, ask your contractor to explain the new HVAC system features, brand, estimated installation time, model, and energy efficiency. Before work begins, you should understand how your provider will size the system appropriately for your home and the price you'll pay.

Compare Warranties

Reputable HVAC companies stand behind their work with warranties. Compare warranties from different companies, bearing in mind that more comprehensive coverage is better. Look for the company that offers the most coverage for a reasonable price.

Get Quote in Writing

Always get estimates for HVAC service in writing before work begins. A comprehensive quote should cover both materials and labor. Make sure you review all terms before signing a contract.
