A Southern Homeowner’s Guide to Seasonal HVAC Cleaning and Maintenance

Your heating, ventilation, and air conditioning unit works hard all year long. First, you’ve got summer, with its triple-digit temperature days. Then there is that awkward age, from summer to fall, when your HVAC system runs mainly on “fan only” to circulate all that fresh, cool air. No sooner do you get used to those temperatures than it starts getting cold, and you change the thermostat setting to “heat.” And then it is spring again, and you often don’t know what to expect. Some days you might need heat, other days call for open windows and a fan-only setting.   If you think this is enough to make you a little dizzy, think about the wear-and-tear it puts on your HVAC system! It’s a recipe for heating and air issues, bad indoor air quality, and possibly an eventual breakdown, most likely either in the dead of winter or the middle of summer. This can result in expensive repair bills — unless you get ahead of it. “An ounce of prevention is worth a pound of cure,” as the saying goes. So let’s take a walk through the seasons and discuss some basic seasonal cleaning and home maintenance tips that will help extend the life span of your HVAC unit.


Springtime is an optimal time for performing light maintenance on your unit. Think of spring as “prep time” for summer. Here are some things you can do during the spring to make sure your HVAC unit is performing up to par:  

  • Replace the blower fan unit filter with a new one (if you haven’t already done so within the last 90 days).
  • Clean around the outside portion of your AC unit, or condenser unit.
  • Inspect the insulation on refrigerant lines going into the house. Check for signs of wear
  • Clearing condensate drain clogs with 50/50 bleach or vinegar and water.
  • Shutting off the water supply to the furnace humidifier.
  • Making certain that the platform below the AC compressor is level and firm.


By performing the tasks mentioned above, your AC unit should be performing at the top of its game when summer hits. Now your goal is to tame the beast known as “kilowatt hours,” or kWh. The more kWh you use, the more money you spend on energy bills. Here are some tips to keep the beast at bay.  

  • Change out your incandescent light bulbs for LEDs.
  • Conserve water. (Most uses of cold water involve hot water as well, which consumes energy.)
  • Improve insulation.
  • Install a programmable thermostat.
  • Apply weatherstripping to windows and doors.
  • Use fans to circulate cooled air.
  • Keep your curtains or blinds closed.


Once cooler weather begins its approach, it’s time to check in on your heating system before winter comes. The moment Fall rolls around, fling open the windows and turn your attention to your furnace or heat source.   Here’s a rundown on everything you need to address before winter:  

  • Check all the insulation and weatherstripping, and replace as needed.
  • Identify leaky ducts and seal them.
  • Install draft stoppers under exterior doors.
  • Reverse the direction of your ceiling fans.
  • Replace the humidifier wick filter, set the humidistat to between 35 and 40 percent relative humidity, and turn on the water supply.

When to Call in the Professionals

While these home tips will definitely help you get the most out of your HVAC unit, there are still times when you need to call trained, certified HVAC professional, whether for repairs or for preventative/predictive maintenance. Here’s when the experts should get involved.

When you first move in

Before moving into a new home, always call a professional for a thorough HVAC inspection. The last thing you want is an unpleasant surprise and expensive repair bill during your first winter or summer in the home.

At the first sign of trouble…

If you begin to notice signs that your air conditioner isn’t cooling effectively or your furnace is about to fail, don’t wait for a complete breakdown before calling an HVAC company. If basic troubleshooting tips don’t solve the problem, the sooner you call a technician, the better your chances of saving money on repairs.

Schedule yearly maintenance service

At least once a year, you should schedule full inspection and maintenance service for your HVAC unit. During this visit, an experienced technician will inspect your entire HVAC unit, conduct a home air quality audit, and provide you with a health report on your system. It also helps the technician identify and solve small problems before they turn into big, expensive ones.

Enjoy reliable heating and air all year around with a cleaning and maintenance contract

The best way to avoid inconvenient outages and expensive repair bills is to set up a seasonal HVAC cleaning and maintenance contract with AAA Heating & Air. With a preventative maintenance agreement, your HVAC technician will show up several times a year to perform routine cleaning and maintenance, keeping your unit in tip-top shape all year round. And if your unit does run into problems, you always have a technician as close as your phone.   AAA Heating & Air offers a Gold Service Maintenance Plan, A Silver Service Plan, and the Standard Plan, which provides for one visit a year. The best thing about a maintenance agreement is that it allows for “continuity of care” — just like your doctor’s office.

How to Choose the Right HVAC Contractor

It’s the coldest day of the winter, so Murphy’s law dictates that it’s naturally a great time for your home’s furnace to start showing the telltale signs of failure. This can be an especially daunting prospect if you have never had to deal with appliance repair — let alone the biggest appliance in your home. How do you choose a good heating, ventilation and air-conditioning(or HVAC) repairman? How, for the approximately $3,500 you are going to pay, do you even choose the right size with the right features? Here are a few questions to ask before you hire an HVAC contractor.

Are They Reputable?

Start your research by hopping online and identifying reputable HVAC contractors in your area. Visit their websites to get a feel for each company, and read their services and terms carefully. If you see a few that look like contenders, dig a little deeper to learn about their reputation. Check them out with your local Better Business Bureau; check with the LLR; call their references if they offer that option.

Are They Licensed, Bonded and Insured?

It’s a good idea to also check whether a company’s technicians are licensed. Most reputable technicians are licensed by NATE(the North American Technician Excellence program), which is the nation’s largest non-profit organization certification agency. ake sure the company itself is licensed, bonded and insured before working with them. In addition, make sure that technicians are cross-qualified to handle gas line installation and repair, and plumbing installation and repair, as both of these may be necessary to installing your new furnace. If not, ensure that the company has these types of professionals on hand, or within a working relationship, to help where needed and to inspect the final installation.

Are They Versatile?

Determine whether the HVAC company offers models from different manufacturers (Trane, Goodman, Mitsubishi, etc.), and if the technicians are trained in installing and servicing each brand. There are about 211 different brands of heating equipment, and thousands of different models, from low-budget items to full-feature and high-efficiency models. A company that offers only one or two brand names may have a good grasp on the intricacies of installing a particular model of furnace. The trade-off, though, is that you have far fewer options. Before choosing a furnace repair service, make sure they are capable of servicing your particular unit, but that they are versatile enough to offer more options if need be.

Do They Offer Additional Services?

To help you keep your furnace or air conditioner operating at its best, a good HVAC company should offer more than just installation and repair. Does the company offer any kind of preventative maintenance contract? Will they come and do tune-ups on your unit? Are they available for emergency repairs if the air conditioner goes out on the hottest day of summer?

Do They Offer Financing?

If you want a top-of-the-line model but can’t afford it, find out if your heating company offers financing. At AAA, we offer guaranteed financing, with payments as low as $59.99. Also keep in mind that your installation may qualify for local, state, or federal tax credits or rebates, so if you choose an energy-efficient model, ask your salesperson or technician about this benefit.

What Should I Look For In A Warranty?

Most HVAC contractors will offer a free, one-year warranty on the furnace (the manufacturer’s guarantee). At AAA Heating & Air, we offer a full 15 year labor warranty on any newly installed Full Replacement HVAC systems. Looking for guaranteed, quality workmanship and unparalleled customer service?
