"A moment ago This company is great. Roy Villa the service technician was very knowledgeable. No threat of up selling. Just explained what was wrong with the heating system and fixed it. This is for a rental house. He told me about the warranty plan they have for heating and AC. It was extremely reasonable. Now I will just have the AC and heater checked before each season."

"They were actually a second opinion for my non-working air conditioner but I went with them because they were very thorough and cheaper then the first company that looked at it. They replaced the same part as the first company quoted but were about $400 cheaper. They also managed to get the part in 2 business days where the other company said over a week. I didn't sacrifice cost for service though, they did a great job and now my AC works better than ever. I would definitely use them again. Another added bonus was that the repairman was a Air Force reservist and I am happy to support our troops and happy to support a company that also supports our troops.

"Technician Angel came on time. He first cleaned our HVAC unit, checked the wirings & parts & performed tests to ensure the unit is running according to standards. He inspected the Air ducts, vents even the attic. He explained everything and showed us the pictures that he took & the results on HVAC heating and cooling tests that were done. Overall a very good job done by Technician Angel I told him to come back after 6 months. Already recommended Airtime Heating & Cooling to my neighbor. 5 STARS"

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

"Will came on time and came in and told me had did several of the homes in my area, so he wouldn't need to do a load-test for our home. I felt a little nervous about not doing a load test because I know too small or too big of a a/c unit both have its problem, but I took it on good faith that he knew what he was doing. He asked me what I wanted, I told him just basic a/c unit., as I wouldn't be using it much (just for very hot days). He provided me with 2 options - a complete new HVAC system ($9,545.31) or just an A/C Unit & Compressor ($7,652.31). He also explained that Carini was extremely busy and that they were 1 month out on scheduling any installations."

"Alex Gold of AirMaxx was personable, knowledgable, and efficient, he came on Sunday of a holiday weekend, and he quickly restored our HVAC. He explained every step, showed the cost of each step, and delivered at the quoted cost. I recommend him and his company for any HVAC issues."

Heating and Air Conditioning questions, answered by experts

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.

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.

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

If you’re looking for an energy-efficient heating and cooling system to heat a compact to average-sized home, then a ductless system is absolutely worth considering. The installation is less hassle when compared to a ducted heat pump system, and because your electricity bills should drop, it’s an excellent long-term investment.
