"I had reluctantly put in a service request through Angi's list after being shelled shocked by pricing from the bigger, more well known AC companies here locally. Philip called almost immediately, understood my emergency (no AC with small children!) and assured me his team could take the job. Within 48 hours, I had a new outdoor AC unit! Philip was fair, straightforward, personable and his crew of technicians were on task and efficient. I give him and his work the highest of recommendation."

"The initial phone call was made to report a gas leak.  The technician was at the house within the half hour.  A complete inspection of the heating system (gas) was performed at that time.  It was determined the pilot light in the space heater located in the basement had gone out and the gas was leaking from it.  Later that evening there was still the smell of gas in the house.  Another phone call was made that night to All in One.  The owner, himself, responded to the call and arrived at the house at 11:00pm.  He worked on the lines performing a bubble test and found the cause of the smell.  Which was in the main line leading to the space heater and in various other spots.  He made the necessary repairs and left about one and a half hours later.  He restarted all the pilots lights and stayed until everything was functioning properly and to ensure the leaks were plugged.  I do not smell gas in the house at all.  I can now rest easily knowing the leak has been taking care of.

Air Conditioning questions, answered by experts

Ideally, an AC system should never need more Freon (a popular refrigerant) because it circulates in a closed loop. However, refrigerant leaks are not uncommon and may occur gradually over 5 to 15 years. If your system has a leak, it will need to be topped up in a process known as an AC recharge. Signs of a refrigerant leak include weakened AC performance, increased humidity in your home, higher utility bills, and a hissing sound from the unit. The cost of an AC recharge will depend on the size and type of your AC unit, as well as the type of refrigerant it uses.

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

Most HVAC service calls include diagnostic fees, which could include checking on a specific issue you’re experiencing or running through a routine inspection checklist. If you called for a particular problem, the service call will also include an estimate to fix the issue, including materials and labor. Depending on your HVAC technician and the service you requested, you might also get a general inspection of your system components to ensure everything is working as intended.
