"It went amazing my kids and I have so many allergies specially in this season and it’s so hard when we can’t even feel good at home because of the dust in the air conditioning duct, I have been paying for many services with different companies and it just worked for few weeks until I hired this company and their work exceeded my expectations. Highly recommended. Thank you for the services"

"This is not my first review of Joe's Plumbing but they just keep knocking it out of the park. Decided to do pipe replacement on a 60 year old home do to multiple leaks. Wanted to get it done before the cold came, and Joe's did the job on time, under budget, and the quality was second to none. When they found they couldn't turn the water off from the street, they kept moving on the job and did a fantastic job. Joe's was the first called and they have not let me down yet. Thank you Ace and Reg!"

"Joe was fantastic. He responded quickly to my inquiry, stayed in touch prior to the repair visit, arrived promptly and quickly resolved the problem with my central AC. His fee was very fair. Previously another HVAC company (not from Home Advisor) told me the unit was unrepairable and needed to be replaced. I highly recommend Joeâ  s company All-in-One for your HVAC, plumbing and electrical service."

"I hired MDJ to look at the options we had with our old central a/c unit. After considering everything we decided to install a new unit. MDJ did not pressure me in any way, & they were quick to respond. Our new a/c is installed & working fine so far. It only took 3 days in total to meet up, & get the new unit installed. I'm very glad we found MDJ."

Heating and Air Conditioning FAQs, 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.

The DOE is phasing out AC units with SEER ratings that fall below 14 or 15. The exact minimum rating depends on your region. In the northern United States, new ACs must have a minimum SEER rating of 14, though you can still buy and install older systems as long as they were compliant when they were manufactured. In the southern and southwestern United States, you cannot buy or install older air conditioners with lower SEER ratings. The minimum rating is between 14.5 and 15, depending on the power of the unit.

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

If you’re planning an AC replacement, choosing an AC with a higher SEER rating may save you money in the long run. Tax credits could cover as much as 30% of the job, and you’ll notice smaller utility bills (particularly if you live in a hot climate where you need to constantly run the AC). Generally, you can expect to pay between $350 and $1,500 for each SEER rating increase. Weigh the cost against your typical utility bill to figure out what’s worth it to you.
