"This was our second call to All Temp for service. Mike was our technician and he is very knowledgeable and professional. He gave some good advice on cooling our house, what to look for in the HVAC system in a new house (we are looking), and didn't try to up-sell me on things we didn't need. He was quick with his assessment and work. We'll be calling them again if we have HVAC issues."

"Buyer Be Aware: If the Person doing the work tells You that you Cannot Use Your Credit Card (if After 5:00 PM), Do NOT Listen! Pay the Following Day during Business Hrs.!! Also, when my New HVAC System was being installed 2 Days After Duct Cleaning, the HVAC Contractors called Me into the Basement and Showed Me the Inside of the Ductwork just after Opening it: Tons of Debris Remained Inside! Hopefully, if You Hire, Your Experience Will Be Better...Good Luck!"

"You absolutely need to hire these guys for whatever heating/cooling project is on your list. We had been ghosted by 4 HVAC companies in 9 months. Carlos Jr. called me at 9AM and by 4:30PM I not only did I have a working AC but I had an all new and upgraded unit. I am so impressed by their quick and QUALITY work. They were kind and understanding."

Heating and Air Conditioning questions, answered by experts

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

You may be able to clean mold from your air conditioner in some cases. If the mold growth only takes up a small area, you can use either vinegar or bleach mixed with water to remove it. Larger areas of mold should be left to the professionals, though. It's also a good idea to leave mold removal to the pros if you are sensitive to mold or have asthma. 

The decision to put your AC unit on the roof or ground depends on the climate in your area, the roof shape, accessibility, and budget. If you live in a warm climate or don’t have existing ductwork, it’s likely best to stick to a traditional AC unit that sits on the ground. However, if you lack yard space, live in a mild climate, and have easy access to the roof, your home may benefit from a rooftop AC unit. 

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

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.
