"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

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill. 

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.
