"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

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.

Yes, high-efficiency models reduce environmental impact with lower energy use.

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.
