    Elite Comfort Systems

    I was a new homeowner in 2022 when Vic (the owner) and his company, Elite Comfort Systems, saved my…read morefamily (including the feline members) from sweltering in 100+F degree weather by diagnosing and repairing my air conditioner. Since then, they've serviced the almost 22 year old system at my home, nursing it along. With each semi-annual "check-up" service, they advised me on what I needed to do, and what could wait. When funds were tight, they suggested stopgaps to help. Because of this history, when Alex showed me that my heater was leeching carbon monoxide into my home, I knew I could trust him. While I waited for my appointment, I was provided with space heaters gratis. This IS an independently owned business, and they treat customers like family. Ozzy (Osvaldo) and Anthony installed a new heat pump and air conditioner for me last week. They were at my home three days. Not only were they professional, friendly, and polite, they were also respectful of my home--taking time EVERY day to cover my carpeted areas, covering their boots as they came into and exited the house, and cleaning up any installation debris before they left each day. Ozzy and Anthony discovered that a part of the original system was not going to work as efficiently with the new system (the dampers) given the difference in the size. Ozzy explained the difference to me, noted the cost, and the pros and cons. He didn't pressure me to upgrade the items but he made sure I had enough information to make a decision. At the end of the installation, Ozzy took the time to show me how to use the new digital thermostat controls and gave me tips on how to use the system economically. He provided me information on how to follow up if there were ever any problems. Just like other times, Vic called a few days later to see how things were going (I missed the call, but still...so so kind and thoughtful). It's a lot of money to replace your entire HVAC system, no matter which company you use, but hiring one where you know you can trust the company. Simply put, you'll never have worries about trusting Elite Comfort Systems.

    I installed a unit, but apparently I didn't ferrule my lines very well, and it lasted a week. (the…read moreold lines from the previous Chinese unit were 6 inches of copper soldered to aluminum to 6 inches of copper, which gives 4 more places to leak so I didn't use them; that unit's motherboard failed.) They wanted $4,169 to fix my lines (new ferraled lines from the manufacturer are $150, and to refill ($125 in freon) total job one hour for me To redo everything, $8,929 I recently installed in my 2,400-square-foot home a whole new heating and AC system for $24,000. They also wanted to redo my 115 volt lines to 220 volts. This system does NOT run on 220 volts. He mentioned how it uses less electricity. NO, it does not. I'm an electrician. 115 volts, 20 amp is the same as 220 volts, 10 amps because 220 volt is 2-115 volt lines, which are 10 amps each line = 20 amps. and he said my water drain wasn't installed properly, but it was according to the manufacturer. (just drain it outside, period.) My unit from 'Heat and Cool' was only $400 without the AC lines; this is the 4th unit I've installed and only one that failed my installation. it comes with a 1-year warranty, 5/7 if you get an ac guy to install it and 7/10 for an extra $150 Well, Elite isn't going to slap their sticker on this unit, so they will lose future business. That's NOT good business; that's simply greed

Air Synergy failed to perform any of those tasks causing us as the customer to be excluded from the program and rebates in the amount of $14,000. Air Synergy was directly responsible as an "Approved Contractor" for failing to perform the work prior to the start of the programs approved timeline.

During the estimate phase, Constantine was a breath of fresh air. Instead of pushing generic upsells, he actually "downsold" us by engineering exactly what we needed to work seamlessly with our home's downflow ducting. He was honest, straightforward, and clearly explained the system without any high-pressure sales tactics. For the installation, Mike and Diego were our crew. They arrived a little past the initial 9am window on the first day, but they worked incredibly hard and got the entire complex job done right on schedule. At the start of Day 1, I handed them a simple "homeowner's QA" list of things I wanted to check with them at the end. They were super nice, listened, and gladly accommodated every single request. The workmanship is top-notch. They perfectly sealed the exterior wall where the lineset exits, helped me get the Kumo Cloud Wi-Fi connected to my phone, and hauled away all the old debris, leaving the site spotless. As a testament to their technical skill, when I asked about the refrigerant line vacuum test, they had pulled it down to 350 microns--which is a great number and proves they don't cut corners! Pics attached of the final setup. If you want an HVAC company that is honest in the office and expert in the field, we highly recommend the Galaxy team!
