"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."

"In May of 2021, CR Mechanical replaced our HVAC equipment (furnace and AC), and installed a new air scrubber and an ecobee thermostat. We were very satisfied with their work (exceeded expectations), and Craig is an excellent installer (that was most important to us). The ecobee was defective out of the box, and he reinstalled our old thermostat and was back the next day (as promised) to install a replacement ecobee. Everything works great."

"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!"

"I needed a new HVAC. I received a prompt bid at an extremely favorable price. The technicians who installed my new unit were extremely knowledgeable and personable! They finished the job in one day, even though they had estimated it would take two whole days. They cleaned up after themselves in a marvelous way."

"They've put in a new furnace, water heater, AC, etc. They are very reliable, but not inexpensive. Everything they do is quality and they only work with quality people. I had a problem with the air compressor on our AC right after the warranty had expired. Cahill said that they work with that company all the time and that part shouldn't have gone out that quick. They said they would talk to the company and see that it is made right, and they did."

Heating and Air Conditioning questions, answered by experts

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

Both evaporator coils and condenser coils are recyclable and contain valuable, sellable metals such as copper and aluminum. Not only is it more earth-friendly to take them to a local metal recycling facility, but you can also trade them in for cash. Also, once the coils are removed from the system, they won’t have any traces of refrigerant, so you won’t have to arrange for recycling Freon or R-410A unless you’re disposing of the entire AC system.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.
