"We found CLIMATE MECHANICS from their stellar reviews while searching for a knowledgeable and competent HVAC company. For years, we were dealing with a condensation problem with our LG mini split air conditioner, and no one could find the source of the problem. We can honestly say that we've never experienced a company like CLIMATE MECHANICS so committed to making things right. Nate, the awesome climate mechanic that came to our home, and Robert, the owner of the company, could understandably have walked away because they did not install the system and were not responsible for the problem. Nate worked for hours trying to locate the problem. In the end, after so many years of leaking, CLIMATE MECHANICS went above and beyond and resolved our ongoing problem. Toni, their wonderful contact person, told us repeatedly that Robert just wanted us to be happy in the end. And we are. Totally. Thank you Robert, Nate and Toni."

"

They came in the first vent they came to

took off vent cover cut middle piece of metal on frame of vent . Then they jammed their hose down the vent and went to other vents  and blew air into them to clean lines. All the other times I had my ducts cleaned it was done from the basement...I'm not sure how well this other way worked.

"For over 20 years my wife and I used another A rated Angie’s List heating and air conditioning firm and we have given them good reviews in the past. Recently our 20+ year old heater started acting up. At times throughout the day or night the burner wouldn’t ignite and we would be without heat. After seven service calls and various parts at the cost of $700.00 our old service company could not repair the heater and the problem remained unresolved. So we decided to get estimates to replace our entire HVAC system mainly due to it’s age and this unsolved problem. Vaughan Heating and Air Conditioning was on our list of acceptable companies to speak with due to their Angie’s List A rating. We called Vaughan and they sent Tony Pellegrino to our home the next day. My wife and I were very impressed with Tony. He spent over an hour at our home scoping out our basement, configuring our new system and answering our questions. Later that day we received the Vaughan estimate that Tony sent by email. I called Tony and he spent another hour on the phone addressing my questions and concerns. We received the other competitor's estimates over the next two days. We accepted the Vaughan’s estimate which was $1,100.00 more then the lowest estimate and $2,500.00 less then the highest estimate we received. Our choice was based on our comfort level with Tony, the price of the job, the longevity of the company (established in 1937) and the quality of the heating and air conditioning units that Vaughan installs. We accepted the Vaughan estimate on Saturday evening and Tony scheduled our job that coming week on Tuesday (for the heater) and Thursday (for the air conditioner). The reason for the one day in between work was because they squeezed our job into an already full week of installations and we were really pleased that they did that for us. On Tuesday morning at 8:30am the installer’s, Marcus and Jeff were at our house ready to start the job. These guys were friendly, professional, extremely competent and also very neat and clean, covering our rugs, etc. Jeff and Marcus did and exceptional job installing our new HVAC system. It’s “state of the art”! My wife and I are extremely happy with the job Vaughan Heating & Air Conditioning did and we could not be more comfortable, then we are now, in our home. A great price, a great people and a great job! We highly recommend Vaughan Heating & Air Conditioning! Len & Lorraine Fedullo"

"Very happy with the job these guys did. I was a little hesitant on the price quoted for my little house, but glad I had it done. These guys did one **** of a good job. First, they arrived 15 minutes early. Then they walked me through the job step by step. When they were done, my carpets and upholstery looks and smelled brand spanking new. The ducts in my 54 year house were spotless and I could tell the difference in the air quality right away. And they cleaned my one little dryer vent for free. A+ service. I definitely recommend this company."

Air Conditioning FAQs, answered by experts

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

No, for two very important reasons. First, it’s illegal to release refrigerant into the air or ground since it can be toxic and cause environmental damage. Technicians typically pump old or extra refrigerant into separate tanks for special disposal. Second, without professional equipment to read refrigerant pressure and levels, plus the AC’s suggested requirements, it’s impossible to know if you’ve removed the right amount of refrigerant. Stay away from a DIY solution here and seek an expert with the right tools.

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.
