"Went very well, considering I needed my furnance fixed on a Sunday. I was able to call up at 7am and the tech was out to my house later that morning. Juan did a great job, fixed the problem and explained to me what he did. I would hire this company and ask for Juan if you have any HVAC needs."

"The two men that came to install the units were great! Their attention to detail, and thoroughness was amazing. They were open to discussing different ways to install line sets, etc. This is not typical of most contractors. In fact they were checking in with me frequently to ensure I was happy with the way the job was going. My only complaint would be that the owner's communication was spotty after signing the contract. I received a bill to pay for the system, but it was not yet installed or even scheduled. After several messages without response from the owner I contacted the finance company to put a freeze on the account as I was concerned I had not heard from him. I received a call from Don 2 days later scheduling the install for the following week. During that discussion he did mention he was out of town for the last two weeks in a poor cell phone reception area. This very well might have been the case, but a heads up to me would have been nice. I was initially told 2-3 weeks from date of signing contract. It was a month later without communication. It could have all been a misunderstanding, either way Don was pleasant to deal with, and stuck to his bid. I am happy with the process and install and would encourage anyone to utilize quiet corner mechanical for their HVAC needs."

Heating and Air Conditioning FAQs, answered by experts

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.
