"Shavitz is great. They're not the least expensive place you can find, but you get what you pay for. They are always punctual, and the technicians are always helpful, professional, and polite. I have used them to repair a leaky duct and they were prompt about completing the work, which is great because I needed to schedule drywall work once they were finished. I recently had my AC go out on a really hot 95º day, and they were admittedly busy, but a tech came to my house and stayed until 9-9:30pm to making sure our air conditioner was working. He also recognized a leak and they quickly processed our warranty claim that was set to expire in the next two weeks. Problem totally fixed in less than a week. Good contractors are hard to come by - I couldn't ask for anything more."

"The technician came out yesterday, June 5th and did a diagnosis on my air conditioner as there was a significant cooling disparity between the upstairs and downstairs of our two story townhome. I was expecting to possibly replace the A/C as it is getting older. However, the technician stated the AC is in good working condition and that there was a slight leakage factoring into the cooling discrepancy. That was a much less expensive repair or fix vs. replacing the whole equipment. I appreciated his honesty, time spent communicating the issue with me and professionalism. I would definitely use All Temp Heating and Air Conditioning again and recommend them to anyone dealing with air conditioning issues."

"The air duct cleaning aspect was good. I had issue with a few minor things that happened while the service was performed. Tom from Mr. Duct, quickly responded to my concerns and remedied them as best he could. The workers arrived on time and on schedule, were polite and quickly got to work. I discovered the issues (minor) after they left, but Tom quickly followed up with me. I will probably use them again as they took the time to make sure I was satisfied"

"I have been a Four Seasons customer for about 20 years, and normally I have been very pleased with their performance and responsiveness. This last encounter has been a disaster from the start as described below. I am happy to say however, that Four Seasons Customer Service reached out to me to rectify the issue, which was satisfactorily enough for me to revise my rating. My AC issue was mis-diagnosed resulting in unnecessarily having to endure 90 plus degree temperatures for four days. Mind you, this occurred 5 weeks after my tune up. I was told the compressor needed replacement, then my appointment to install a new one was cancelled because the parts were not in and nobody notified me. The first person I spoke to about the missed appointment gave me an attitude and no resolution. Second diagnosis by two technicians was the coil had a leak. Another day of 90 degree waiting and had the coil replaced by a third technician. I am still not sure that my AC has been fixed however because after three hours of running the unit it did not feel like it was blowing cold air as it used to. Hard to tell as the temperatures have been too low to use the AC. Hopefully we will have a warm spell so I can know for sure and I will change my review to recommend."

"I had the most positive experience working with Bob and Anthony on a full Furnace/AC installation. Both systems were approaching 15 yrs old needing repairs that would not have made sense to continue putting money into. Bob came onsite for a free consultation and very clearly communicated detail on my options, even making recommendations for further cost-saving improvements. They fit me in right away and worked diligently with the installation. I couldn't be happier with the end result...should have called these guys months ago!"

"We would absolutely hire Toptec again. They were easy to contact and set up time with for our appointment. The man that came to our house, (Dr.)Dre, showed up promptly and was extremely knowledgable and friendly. He took the time to literally explain every piece of our furnace, humidifier, and air conditioner (we're new homeowners) and answer any questions we had for him. He examined everything quite thoroughly and gave recommendations for any parts that needed replacing. You can tell that he is passionate and knowledgable about what he does. He even took the time to power wash down our air conditioner and remove a lovely dead mouse that was stuck in there. I will definitely be requesting Dre to come back for anything we have done! Thank you!

Air Conditioning FAQs, answered by experts

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected.
