"Loomis met and exceeded all of my requirement and expectations. 1st I live out of state thus throughout the entire transaction/installation we communicated via cell phone and email. I needed a fast diagnosis bam they were there in two days. Together we determined more cost effective longterm to replace unit. Living in Colorado the cost for installation of same Goodman unit was $2,000 more. So Loomis was cost effective, installation was flawless and customer satisfaction thru the roof. Top it off they asked if I wanted ac unit anchored to platorm? We live on water and got hit hard by Ida. I said yes how much? Drum roll please. No charge. Sorry to be long winded however I have written my fair share of poor reviews for service and products. With that said great companies need kudos when they excel at their jobs. Thanks again and when my daughters two ac units need replacement you will be our first and last call. Karl"

"Paul called me within minutes of my request. He was able to get to my house within only a few hours, which I thought was outstanding! He quickly identified the issues and fixed on the spot. Later in the day I had an issue arise. I called Paul and he walked me through some troubleshooting and i was up and running again! Great quick service. I would use his service again if I need AC repair/service."

My most recent service was air duct cleaning and I have noticed a tremendous difference in the reduction of dust that settles on my furniture as well as less issues with my allergies. I will continue to use Mike and Hagerman for all my HVAC needs."

Air Conditioning questions, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

No, it's not safe to keep using your unit when it's frozen. Not only can running a frozen unit lead to damage, but it can also potentially overheat, making it a fire hazard. Therefore, it's always best to turn off the AC unit as soon as you notice any ice.

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.

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.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.
