""Outstanding Service and Expertise from GIL Air LLC" I am incredibly impressed with the service provided by Gil and his team at GIL Air LLC. I recently had a new HVAC system installed in my house, and the entire experience was fantastic from start to finish. Gil was not only punctual for our appointment but also incredibly knowledgeable about the entire process. He took the time to talk me through every step of the installation, explaining exactly what needed to be done and why certain choices were made for optimal efficiency in my home. This transparency and clear communication really put my mind at ease. The work was completed efficiently, and the professionalism displayed was top-tier. I highly recommend GIL Air LLC to anyone needing HVAC services. If you want a job done right by someone you can trust, look no further!!!"

"I was able to get on their schedule the first business day after calling. Daniel came out and quickly diagnosed the issue and got my heat working again. He also provided a couple of safety addition suggestions to prevent overflow/flooding during the summer months. It only cost me the standard service charge, and enrolled in a PM agreement for both HVAC systems. I would absolutely hire again."

Heating and Air Conditioning questions, answered by experts

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

The cost of R32 refrigerant is about the same as the cost of R410A refrigerant, the most widely available type of refrigerant today. However, R32 systems use about 20% less refrigerant than R410A systems, making the refrigerant less expensive overall.
