"Ali came over to our home when we called with a concern of the air flow in our central air conditioning system. He checked the return, the air flow, the temperature at all of the vents, and the entire system. It had more to do with the age of the system and gave us suggestions on how a different filter could increase the air flow. He did all of this and refused to take any money for his time. He is a true honest professional and someone that we would recommend to everyone."

"I have used Speer Air for several years for HVAC preventive maintenance at my home. We recently expanded and they installed a package unit to take care of the expansion space. The work was good and they have been back for adjustments as necessary."

"I was in desperate need of an AC unit repair and Kyle came to the rescue. Iâ  ve owned my home since 2019 and have been looking for and honest and reliable AC technician. Iâ  ve used a couple of other technicians but Kyle will be my go to moving forward. He kept me informed of everything he was doing and educated me on how my unit should be running. He even gave me info for what filters I should be purchasing to help my unit run efficiently. He gave me several options with regards to repairs and I went with the higher priced option because it was so reasonable and I didnâ  t want to cut corners. I will be scheduling my routine maintenance with him for the summer and winter. Iâ  m so happy I finally found an AC technician I can rely on. I highly recommend him."

"I'm very happy with the work performed by this company plus the technician explained to me in detail of the work he was going to do as well as the correct way the dryer vent should have been installed before as the the exhaust vent was connected to the lower vent instead of the higher vent, saying that connecting it to the higher vent gave it more room for the lint to collect before it started clogging up the exhaust. The air duct cleaning was also conducted professionally and I have no complaint about their work. I would hire them again the next time my heating and cooling ducts needs cleaning. I'd recommend them to my friends."

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"ABC Castellos Heating & Cooling came when they said they would and took the time to explain to me the Homeowner, what they were going to do. They also performed a AC System check which they did as part of their service. They also took the time to ask questions about my system. Desmond was very professional. i would recommend them to any one who needs their service."

"My home warranty contracted out the job to Phase II. Robert came to troubleshoot a 30+ year old AC unit and was very honest about everything he found faulty. He was instrumental in convincing the warranty company to replace the entire condenser unit rather than continue putting band-aid fixes to this ancient unit. Few weeks after he replaced the unit that cools the upstairs, the other unit that cools the downstairs fails as well (also over 30 years old). Since he was already familiar with everything, the second unit was replaced as soon as weather permitted. I didn't even have to be home the second time since the work was outside anyway. The promptness of his repairs can not be overstated. He helped get us back up and running as soon as the parts were available on the next clear day, which we couldn't be more appreciative since we have both a toddler and infant at home. Also, this was during a heatwave when most of the week was 90+. On top of this, my son's 1st birthday party was coming up and we needed the AC back asap. We can't recommend Rob and Phase II enough, a true professional"

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.

There are many signs of a bad AC fan motor, including if the fan blades don’t spin when the AC kicks on or if they keep spinning when the AC is off. The AC fan cools down the condenser coil, so a faulty motor can also cause the system to overheat. Unusual noises in the exterior AC unit, including grinding or rattling sounds, may also be a sign that the AC fan motor is worn out.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.
