"Speer Air just completed a complete overhaul of my existing HVAC including an upgrade of part of our system. The entire experience from initial sales visit to completion was great. Throughout the installation, the team was friendly, always available to answer a question, clean and respectful of my 3 young children (making sure nothing was left behind or any debris that could hurt them). System is operational and very satisfied. Highly recommend them."

"The HVAC tech Jay was everything a homeowner could wish for in a contractor. He called 30 minutes before he was scheduled to arrive to say he was on the way, he was on time, friendly as can be & extremely knowledgeable, hard working & honest. He tried everything he could think of to repair the condenser before telling us it needed to be replaced. He didnâ t do what others would and just give us a price, he gave us options as far as equipment was concerned & the different price points. The folks at AAA HVAC went above and beyond with our system. What started out as a simple Condenser replacement turned out to be needing an entirely new HVAC system because the old system was completely mismatched & undersized for the size of the house & condenser we have, causing all kinds of problems. Including our original condenser dying in under 5 years. Long story shorter, it was an unexpected financial hit and they not only inspected, quoted & replaced everything within a day, they worked with me on financing. Jay even returned the very next day to fill out the invoice with all model & serial numbers that was requested by the manufacturers for any future warranty repairs, just registering the equipment on line was not good enough. I would without a secondâ s hesitation recommend AAA HVAC & Jay. I look forward to working with them on all our Future HVAC needs."

Heating and Air Conditioning questions, answered by experts

Most HVAC surge protectors last about three to five years, depending on how often your home experiences blackouts or brownouts. If your unit is susceptible to more frequent electrical surges, consider replacing your surge protector every two years. Consult your HVAC professional to determine when and how often to replace your HVAC surge protectors.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.
