"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. :)"

"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."

"Michael, the estimator, came out and got all the information. He was very professional and even talked about various different options including putting the heater in the attic. He was very knowledgeable. I chose to go with another company, but I believe that Albert Nahman Plumbing and Heating would have done a great job on the work proposed."

"These guys are just excellent! I made a few mistakes before I got lucky to find New Millennium HVAC. They were professional from the beginning to the end. Jose did a thorough job, cleaning the dryer vent. It was not a straightforward issue and I was afraid that we’d have to open the wall to cure the blockage. However, Jose was able to fix it. He’s an experienced professional excellent at his job, trustworthy and overall great to deal with. I’m a happy customer for years now and will rely on these guys for any HVAC related issues."

Heating and Air Conditioning questions, answered by experts

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

There are a few reasons your AC is running but not cooling your room. Thermostat issues and dust and debris, which can clog your system, are common problems. It could also be a broken component, such as a compressor, blower fan, or evaporator coils. You’ll need to call a pro to diagnose the issue.
