"I first contacted Valley to get a quote on how much it would cost to get air conditioning installed. I live in an older town home that is approximately 1100 sq. ft. They sent someone out to take a look and see what was involved. He was very professional and explained what was involved including getting permits from the city. He quoted the amount and provided me with an invoice. I contacted them 3 months later to say I was ready for the install. The installation turned out to be quite challenging due to the way my home is constructed, but Valley made it work. The service person had to stay a few hours longer but I wasn't charged anything extra for it. They stuck with the amount of the estimate that was quoted. It's only been a couple of months since the install, but I have to say my only complaint at this point is how cold it gets when I turn on the air. But that's a nice problem to have. :)"

"We recently installed solar panels on the roof and continued the 'infrastructure upgrades' with a new furnace and central air conditioner, having cooled the house in summers with breezes and fans and insulation, but no A/C.
Comfort Energy was more expensive than other bidders, but my spouse (who drove the process) felt the most detailed options and trade-offs were presented by Carlos Gonzalez.  So we went with Comfort.  The installation team was VERY professional and courteous, working hard to minimize disruption (we work from home offices, and have dogs...) while doing the work, and leaving an immaculate workspace at the end of each day.
The job, by coincidence, finished on the hottest day of the summer thus far and one part of the furnace install involved opening all windows and blasting the furnace on high for a number of minutes to clear out some factory material/fumes.  This was fascinating on a 90-100F degree day.  That part concluded, we shut the windows, turned on the AC and the house became cool again.
Next will come the post-install QC/QA check, and the next 2-3 years of on site tune-ups and services. So we'll see how that goes.  But so far so good.  We'll never know of course if different equipment would have been better/worse, but we do know that the UI of the experience seemed to go quite well and very, very professionally.

"Global Comfort installed a full HVAC system in my home; 7 new runs for air, new AC unit, new furnace and a new Nest thermostat, all electrical needs. Rudy and his team are respectful, efficient, punctual, competitive in pricing. Rudy walked me through running the system for its first time and explained all the stuff for a brand new system in a house that never had AC. I'm very thankful for the work they did. Highly recommend because their customer service is top notch."

"John did an amazing job with our HVAC system! From the moment he arrived, he was professional, knowledgeable, and took the time to explain everything clearly. His workmanship was top-notch, and he made sure everything was working perfectly before he left. It?s hard to find someone who genuinely cares about doing quality work, but John definitely does. If you?re looking for an honest, reliable HVAC contractor who takes pride in what he does, I highly recommend John. I couldn?t be happier with the service!"

Heating and Air Conditioning questions, answered by experts

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

Yes, it's normal for air conditioners to leak tiny amounts of water due to condensation. Under normal circumstances, all excess moisture travels to the drain pan to be pumped through your system's drain line. You should call a technician to diagnose the issue if you're noticing frequent leaking or pooling. It's also important to investigate if your homeowners insurance can cover water damage.

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.

Troubleshooting common issues with your AC often sheds light on a problem with the compressor. Signs that you need to replace a bad compressor include your AC blowing warm air, short cycling (turning on and off), making strange noises, and blowing less air overall. Since these problems can stem from several areas of your AC, always call a local AC repair team to confirm it's the compressor.
