"Went well. The installers showed up on time, installed the equipment and explained how everything worked. They even completed the paperwork for my rebates. They scheduled the inspections for me on convenient dates. The county building inspector found two fixes were needed (locking caps on compressor and UV listed sleeve on AC outlet). On the scheduled day for the repair they showed up 15 minutes early and fixed the problem. Passed subsequent inspection with no problem."

"I reached out to Angi’s to find a HVAC company to help with my AC that was blowing hot air in the summer. I got super lucky when I found MSR Heating and Cooling. They arrived on time and assessed my situation. I appreciated the time they took to explain the issue in ways I understood as well as recommend the best option for me. The estimate quote was fair and there were no surprise expenses to repair my unit. I can’t thank the owner, Moises enough for a job well done. His professionalism, knowledge and skills are reflected in the quality of work performed. I would highly recommend this company for your next repair."

"Danny treated me like an old friend with helpful and timely service. It was refreshing. He inspected the unit, found a failed capacitor caused by an add-on Michael and Sons installed last inspection. Danny replaced the failed part, removed the add-on, and I was back in business in less than 30 minutes. I have a new HVAC provider!"

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"Technician arrived at exact time he specified. He immediately diagnosed the problem and made the repairs. He was courteous, professional, and handled the job quickly. He recommended what I needed to do in the future to avoid continued problems. Will be following up with McCrae in the next couple of months.

Humidifier Repair FAQs, answered by experts

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Whether you’re facing significant humidifier repair costs or it’s time to replace your humidifier altogether, it’s understandable to question whether the expense is worth it. Still, there are many benefits of whole-house humidifiers that you might miss, including improved indoor comfort, improved breathing and sleep, better hair and skin, and even increased home value. Either way, the answer is subjective, so it’s helpful to evaluate your home’s humidity without the unit running and give it a few weeks to see if you notice a difference.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

Several styles of HVAC dampers exist, some with motors and some without. The various types include butterfly, blade, louvered, guillotine, and more. The names describe their construction style and how air moves through them. Motorized versions work through wiring connected to a control panel within the HVAC system. Manual versions allow an operator to decide which way to send the airflow and make the adjustment by hand. 

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.
