"In preparation for replacing my HVAC system, I went through a few different estimates. The reason I chose Air-Tech was not because of price, but because I was impressed by the details provided to me. Rod was great. We went into the attic, reviewed all the components inside and out. And we discussed the scope of the work. Once I agreed, he gave me a start date\time. The crew showed up on time and worked hard for two days. Not only was I comfortable with Rod, but the crew was great. My new system is in place and I couldn’t be happier that I chose Air-Tech. If you’re in the market for a new HVAC system, do yourself a favor and call them. You won’t be disappointed."

"After reading reviews on Angie's List and finding out that they do installations for Costco, we chose Around the Clock (even though they were the most expensive of the 3 quotes we received) because we wanted to make sure we did not skimp on such a major project - installation of a new HVAC system. While the system is working great and our house is much cooler than with our swamp cooler and/or window AC units, we were disappointed with a few aspects of the job. As far as when the crew was on the job... they were on time, clean, and the job got completed in the time that they said it would - 2 days. My concerns came up in the days/weeks after the job was completed when a contractor came to the house to look at some additional work being done. Part of the quote from our job was that they would "remove" two existing floor gas heaters in our home. When the contractor and I were looking at repairing the hardwood floors where the heaters have been removed, we found that one of the heaters had actually just been left under the house in the crawlspace. A few minutes later, I asked my contractor to check out the attic because I knew that the workers had smashed an asbestos vent pipe from one of the old heaters so they could run electric wires through it from the crawlspace under the house up to the attic and eventually the package HVAC unit on the roof. I know that health issues arise with asbestos when it disturbed (like smashing it apart and leaving it exposed in the attic.) The contractor confirmed that this was the case and he was rather alarmed and surprised that a "retail" top-dollar job had been done with these methods. After talking with the owner, Alan, about my concerns, his response was basically this is the way that things are done. He said that leaving the heater under the house is called "dropping" the unit and that the unit was too big to remove out of the crawl space. I think that with some effort and a Sawzall it could have been removed, but either way, I wish that they would have been clearer that they were leaving smashed up appliances under our house. I told him about the asbestos pipe and he told me, again, often times that is "how it's done" because it's the easiest way to get the wires through the house. When I told him I had safety concerns about the asbestos being exposed, he said that the workers should have put some kind of coating on the exposed areas as a protection against any of the asbestos fibers getting airborne. I sent him photos confirming that there was no coating applied. During this call, he mentioned something about "sealing" the unit to the roof (to protect against rain penetrating where the HVAC and the roof meet) and that it had not been done yet because they thought maybe we were getting a new roof very soon. This was the first I had heard that the job was not complete and I don't know where the idea of the new roof came from other than our roof is old and going to need to be done in the next few years. Alan said he would send out someone to coat the pipe and do the roof "sealing". They came out that day or the next to do the work. After talking to the worker about the pipe (same guy who was heading the crew on the installation days), he acted like this was a waste of time and told me, "We never put this coating on these asbestos pipes when we break them." That was disconcerning and it made me feel like the owner doesn't really know what his crews are/are not doing or, more likely, that they just are doing whatever they need to do to get the job done quick, cheap and easy. Overall - the big disappointment for me and my wife... if we wanted the job to be "quick, cheap, easy, and maybe cut a few corners, we would have gone with a different HVAC company that was much cheaper, and we would expect that because "you get what you pay for", but we didn't, we went for the retail installer and feel that the job was less than retail."

Heating and Air Conditioning questions, answered by experts

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

No, not all HVAC systems have a fresh air intake, but there are many advantages to having one. For example, a fresh air intake can boost the air quality inside your home and help your furnace run more effectively. Plus, it can make your house more energy efficient, possibly saving you money on your utility costs.

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.

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.
