I recently had maintenance done on my AC and furnace by ASI, and I wanted to highlight the great experience I had—especially with the technician, Jesus. From start to finish, Jesus was extremely professional, thorough, and clearly very knowledgeable about his work. He took the time to carefully service and clean both the AC and furnace, making sure everything was running properly and efficiently. What really stood out to me was his attention to detail—he didn’t rush the job and even went the extra mile by cleaning the outside of the unit, which I truly appreciated. On top of that, his customer service was outstanding. He was friendly, respectful, and took the time to explain what he was doing, which gave me a lot of confidence in the work being performed. Overall, I’m very satisfied with the service and the level of care provided. I will definitely be using ASI again in the future and would highly recommend requesting Jesus if you want the job done right.

After 21 years of faithful service our heater finally gave out. ASI came to the house and we went over a few options as to repair or replace. We elected the latter, and the very next morning ASI was on site with the new heater. Within 6 hours, Sebastian Garcia and his helper had the new heater installed. Sebastian spent some time explaining how to use the new thermostat, which is so much easier to use than the previous one. By the time they left the garage was clean and all the old stuff was carted away. A great job by an outstanding company. This morning I checked my old paperwork and found that the new heater and thermostat were only a couple of hundred dollars more than the ones I had purchased 21 years ago. ASI really offers good prices and great equipment. A special thanks to the service manager Joe Gondak for keeping in touch with the crew to insure there were no problems during the installation

I recently had some plumbing work performed by Sam and Matt who are two team members from ASI and I felt that a comment on their service was warranted. This was a large job. They thoroughly inspected the plumbing and photographed the sections of cast iron pipe that were almost rusted through. Sewer pipes leaking under the house would be a pretty major problem. The whole project took about a week. Sam and Matt were here working hard every single day. I am completely satisfied with the work done, and I can’t say enough about these two individuals. They were polite, punctual, very thorough, and definitely knew their craft. I went under the house to check the installation and it was flawless. One aspect of their performance deserved a special mention. Although crawling around in the dirt under the house was extremely messy, they wore overalls and shoe covers when they entered the house. “White glove” service indeed. If you’re looking for plumbers who excel at their trade, definitely give ASI a call.

FAQs

Frequently Asked Questions

Most HVAC systems should be professionally serviced twice a year — the cooling side in spring and the heating side in fall — so each part is ready before the season it’s needed. Regular maintenance keeps the system efficient, extends its lifespan, and helps catch small problems before they become breakdowns. Many manufacturers also require documented annual service to keep the equipment warranty valid.
Shut off the water right away — use the fixture’s local shut-off valve if the leak is at a sink or toilet, or the home’s main shut-off valve for a larger leak. Then dry the area and move anything that could be water-damaged. Once the water is off and the area is safe, contact a plumber for professional plumbing repair so the leak is properly diagnosed and fixed.
A rising energy bill often traces back to the HVAC system — a clogged air filter, leaky ductwork, low refrigerant, aging equipment, or a thermostat running longer than it needs to. Start with a fresh air filter, since that is the most common and easiest fix. If bills stay high, a technician can check the system’s efficiency and inspect the ductwork for leaks.
Common signs of a hidden leak include an unexpectedly high water bill, the sound of running water when everything is off, damp spots or stains on walls, ceilings, or floors, and a persistent musty smell. You can also check your water meter, then wait an hour without using any water — if the reading changes, water is escaping somewhere. A hidden leak beneath the foundation is called a slab leak, and professional slab leak repair uses leak-detection tools to find the source with minimal disruption.
A well-maintained HVAC system generally lasts 12 to 15 years, with gas furnaces often running a few years longer. Rising energy use, frequent repairs, uneven temperatures, and equipment more than a decade old are all signs it may be nearing the end of its service life. Having an aging system professionally evaluated helps you plan ahead — whether that means AC replacement, furnace replacement, or both — on your own timeline rather than during a breakdown.
Sudden low water pressure across the whole home is usually caused by a failing pressure regulator, a hidden leak, mineral buildup inside the pipes, or an issue with the municipal supply. If only one fixture is affected, the cause is more often a clogged faucet aerator or cartridge. Professional plumbing repair can test the system and pinpoint a whole-house pressure problem.
