10 Best HVAC Companies in Doraville, GA

Signs You May Need HVAC Repair or Replacement

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

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

These HVAC red flags indicate that you should have your system evaluated. A local company can complete an inspection, identify problems, and recommend repairing or replacing your HVAC unit.

Cost of HVAC Installation and Maintenance in Doraville

What you spend on HVAC installation or maintenance is determined by your system type. Common HVAC unit styles include the following:

• Split or mini-split: If your home lacks the right ductwork for central heating or air, you probably have a split HVAC system. Split or mini-split systems consist of interior units that control the temperature in individual rooms, and that are all connected to an outdoor unit.
• Hybrid split: A hybrid split HVAC system performs similarly to a standard split system, but has the capacity to draw on either gas or electricity for power.
• Heat pump: Heat pumps exchange warm and cool air between your home and outside. These systems don't make their own heat or AC, so they work more efficiently in milder climates and may not be as effective during Doraville's hot summers.
• Packaged heating and air: Packaged HVAC systems are good for smaller homes. They consist of a single heating and cooling unit that's usually located in an attic or basement. This unit tends to be efficient, compact, and easy to maintain.

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

Ways to Save Money on HVAC Costs

Taking care of necessary HVAC repairs and replacements when needed is important, but can be costly. Fortunately, there are actions you can take to reduce gradual wear and tear on your system.

• Monitor for potential problems. Monitor your system for issues, for example by routinely checking your thermostat and energy bills. This enables you to address problems before they get too expensive.
• Change filters regularly. Changing your air filters or washing them every 30–90 days allows smooth air circulation through your system. Also try to keep debris from accumulating on the outdoor sections of your HVAC.
• Keep your system clean. Keeping your indoor evaporator coil, ductwork, condenser fan blades, and grills clean helps your system run and reduces the chance of mold growth. The National Air Duct Cleaners Association recommends that you clean your HVAC system when it starts to look dirty.
• 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.

How To Choose a Local HVAC Company

It's important to know what makes a good HVAC company. A properly licensed contractor with the right experience will give you confidence that they can fix your system, providing you with effective heating and cooling in your home.

Compare Multiple Bids

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

Check Credentials

Choose an HVAC company with well-trained 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, individuals must pass an exam (the type of exam depends on the 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 on a state-by-state basis.

In Georgia, all HVAC contractors must be licensed. They can have either a Class I or Class II license. A Class I license requires four years of experience and limits 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. Also look at a company's reviews and complaints on sites such as Google Reviews, the Better Business Bureau (BBB), and Yelp. Pick a company with great feedback and stories of satisfied customers.

Understand Work Details

It’s important to understand what the work process is going to look like. For HVAC repairs, the company should list the exact parts that need replacement and why. Get confirmation that your technician will clean and test the full system afterward to ensure proper functioning. When replacing your HVAC system, have the provider describe the new features, brand, model, estimated installation time, and energy efficiency. Before work starts, ask about the process your provider will use to properly size the new system for your home and how much it will cost.

Compare Warranties

A trustworthy HVAC company will stand behind its repair services and installations with a warranty. The longer and more comprehensive the warranty coverage, the better. Carefully review warranty terms for each contractor and choose the company that provides the greatest protection at a reasonable price.

Get Quote in Writing

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