"This is the second company I have had out here looking at my central air. The first guy said it was the type that cannot be filled. I called this company and he was able to fill my unit and give me pointers on how to clean the outside unit and a price for replacement as well. I will be calling him again when we get ready to replace his unit. Thank you for being sociable and informative."

"We would highly recommend JMSM. John was extremely personable,professional and thorough. We had our gas fireplace inspected and cleaned and John took the time to inspect and test all parts. As a bonus, he educated us on the use in emergency situations...such as power outage. We are very happy."

"Impressed is an understatement! I called Apex when my mom's water heater went out and the company her home warranty sent couldn't repair the shut off valve. They came within 1.5 hours of me calling and were amazing. They repaired the shut off valve and took the time to explain everything. We were so impressed we had them install the new hot water tank instead of using the home warranty company. Charles was able to do everything the same day and worked around the water mitigation company. He was so professional and did a great job. We will definitely be using them for all our future plumbing needs!"

Heating and Air Conditioning questions, answered by experts

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs.
