10 Best HVAC Companies in Lawrenceville, GA

Signs You May Need HVAC Repair or Replacement

If your HVAC system is having issues or getting near the end of its lifespan, it likely needs repairs or replacement from an HVAC company. Look for these signs your system needs service:

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

Arrange an inspection if you notice any of these issues. A local technician can evaluate your system, detect problems, and determine whether you need repairs or a new HVAC unit.

Cost of HVAC Installation and Maintenance in Lawrenceville

Your HVAC installation or maintenance cost varies depending on the type of unit. Common HVAC unit types include the following:

• Split or mini-split: If your home lacks the right ductwork for central air or heating, you probably have a split HVAC system. Split or mini-split systems consist of indoor units that regulate the temperature in individual rooms. These interior units are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but is able to utilize either gas or electricity for power.
• Heat pump: Heat pumps work by transferring hot and cold air between your home and the outdoors. These systems don't create heat or air conditioning themselves, and are more effective in more moderate climates. They may not be as effective during Lawrenceville's hot summers.
• Packaged heating and air: Packaged HVAC systems work best in smaller homes. They consist of a single combined heating and air conditioning unit, commonly located in an attic or basement. This unit is typically small, cost-effective, and easy to maintain.

The amount you spend on HVAC maintenance also depends on what kind of work you're having done. HVAC systems are complex and might require different kinds of maintenance. The prices of some common jobs are as follows:

Ways to Save Money on HVAC Costs

HVAC upkeep is important, but can be expensive. Fortunately, there are steps homeowners can take to reduce wear and tear on their system and lower future maintenance needs.

• Change filters regularly. Air flows through your HVAC system most effectively when you replace or clean the filters every 30–90 days. Also avoid letting debris pile up on the outside areas of your HVAC.
• Keep your system clean. Cleaning your ductwork, condenser fan blades, grills, and indoor evaporator coil regularly helps keep your HVAC system working efficiently and lowers the risk of mold growth. The National Air Duct Cleaners Association recommends cleaning your HVAC system once it starts to look dirty.
• 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 decrease the demand on your HVAC system.
• Monitor for potential problems. Keeping an eye out for problems, for instance by consistently checking your thermostat and energy bills, helps you resolve them before they get too expensive.

How To Choose a Local HVAC Company

Knowing what makes a trustworthy HVAC company is key for an easy 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 at least three HVAC companies. Explain your issues and ask if technicians can inspect your system in person. Review each contractor's diagnoses, recommended solutions, estimated cost, timelines, and warranties. Avoid contractors that pressure you or demand payment before work.

Check Credentials

When picking an HVAC company, choose one with technicians that have the proper training, licenses, and experience. HVAC contractors in all states need to obtain a Section 608 Technician Certification from the Environmental Protection Agency (EPA). This certification is required for all contractors 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 at the state level.

In Georgia, all HVAC contractors are required to 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. A Class II license requires five years of experience and is unrestricted. Licenses can be verified on the Secretary of State's website. Also look at a company's reviews and complaints on sites such as Google Reviews, Yelp, and the Better Business Bureau (BBB). Pick a company with great feedback and good customer testimonials.

Understand Work Details

Always make sure you understand the details of your project. For HVAC repairs, your provider should list which parts need replacement and why. Confirm that your technician will clean and test the full system after repairs are finished to ensure that it’s working properly. When replacing your HVAC, request that the installation company describe the new estimated installation time, model, features, brand, and energy efficiency. Before work starts, ask how your provider plans to accurately size the unit for your home and how much it will cost.

Compare Warranties

Reliable HVAC companies offer warranties on repairs and installations. The more complete the coverage, the better. Compare warranty details between providers and pick the one that offers the best protection for a fair price.

Get Quote in Writing

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