"So many GREAT things to say about Air-Tech. First, I had a split system installed on one side of a duplex about 10 years ago. It was permitted and passed. Less than a year later I learned there were leaks/problems with it. The original installer wouldn't come back as they no longer worked in this geographical area and the European units weren't being used. Thank God they recommended Air-Tech! They fixed the system and offered an annual maintenance check where they come out every 6 months and check for leaks, clean filters, etc. Their office is so wonderful about reminding me if I have forgotten to set up an appointment. Their guys are ALWAYS professional, clean and courteous. Well, two months ago the tenants in the other side of the duplex requested AC and I knew Air-Tech would be great. I called Alex out (what a super nice guy) and he came over the next day I think. I remember it was a Saturday. Since the price of these system had gone up substantially from when I bought it ten years I was shocked. I signed the contract and gave him a deposit but after talking to BF he suggested I get other bids for something that expensive. I called Alex and asked him to put my project on hold for a week while I looked at bids. I think he was surprised because I knew them and the system but I felt like I needed to be prudent. He wasn't rude or short. He was very respectful. The other company's estimators were pleasant enough and I learned about some options for a second gas heating system that I wanted installed at another location. The other company's prices were similar. One added a city inspection which I was doing as an added cost ot Air-Tech's price and the other company added five years of maintenance onto their price. So the prices were a bit higher. I knew I'd be purchasing the maintenance services from Air-Tech so I knew how that compared. I called Alex back about a week later and said: "Let's go. Thank you for the time to check around and feel confident. Armando and Andrew have installed the systems this week and I could NOT BE HAPPIER. I am amazed that Armando knows so much about electrical, gas and mechanical systems. Andrew is very helpful and knowledgeable and quick to make sure things are clean. Every time someone has come out from Air-Tech they are nice, neat, respectful and focused on their work. They aren't taking calls on their phone, they aren't talking excessively, etc. ANYWAY, as part of the installation for the gas wall heater they discovered that there are two gas leaks under the raised property. Someone had installed temporary shut off valves for two previously serviced gas units (a floor furnace and radiator we think). Yikes! Air-Tech was supposed to be done with ALL the work yesterday and while it's not as convenient to be at the property another day I am so thankful that they found the leak and are fixing them without charging me any money! How can they do that? I think it's because they know I'm a loyal customer. I'll be purchasing the maintenance contracts. Thank you Alex, Armando and Andrew. So happy to be working with you!"

"I highly recommend Top Energy Solutions. During the heat wave my air conditioning system blew out hot air. I expected to wait days for a technician to come out. Leor sent one the next morning. The technician quickly located the problem and fixed it within minutes. Their employees are professional, courteous and very knowledgeable."

Air Conditioning questions, answered by experts

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

It is possible to add air conditioning to an older home, but it can be very expensive to do so. Expect to pay anywhere from $6,000 to $17,000 or more for the ductwork and AC unit. You’ll also have to hack into the home’s walls and ceilings to add ductwork, which can impact the aesthetics of an old home.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.
