"Called the company on a Sunday. They arrived on Monday to give me the bad
news I had expected.  My 15 year ole A/C unit had finally died.   Later that day
I received an estimate which I accepted.  The new unit was installed on Thursday
of the same week.
 
The Monday they arrived it was very hot (when else do A/C's die). They
offered and I accepted a portable A/C loaner.  Fast response.  Professional
service. Friendly and capable people.

"Jim Farrell and North Alabama Technical Services rebuilt my computer and provided me with everything I expected and so much more.  He provided the various options in equipment, including specs and pricing, answered all our questions and helped us make the best decision for our purchases.  The computer was completed in a few days, far less than expected, the installation included clear directions for use.  The package also included a good warranty for the equipment.  I was extremely pleased with his service and would not hesitate to recommend his company to anyone with computer service needs."

"Amazing technical expertise and physical strength displayed by Mr. Hall who got the water heater to second floor by himself and safely installed my brand new unit. He's also maintained my AC for the last 7 years and recently replaced my thermostat. He is also knowledgeable and able to make electrical repairs and wiring. He is also an honest person who will advise you accordingly."

"I had debated installing a new system for months. I shopped around; looked at reviews; and decided to go with Major League Contracting Services! The owner, Laz, came from Miami to my home in West Delray to give me an estimate. He said my current unit was too small, and that after 12 years it was time to replace it. We agreed on a price, and set an installation day. They came up on a Saturday and installed my new "York 3.5 ton unit." The air handler is in my attic so it was a tad tricky. After a couple of hours the unit was installed! The installers were very quick, informative, knowledgeable, and polite. Laz even came up and explained the work and even offered to file my registration with York. If you want to work with a local company that goes above and beyond to provide excellent service as well as a competitive then Major League Contracting is the company to use. Call Laz today at 786-344-1846."

"I was in a bit of a bind because my A/C went out and I had a renter coming in 2 days.  They responded to my call immediately. They replaced it immediately. They were there for 8 hours and did not stop until it was done and even bought me dinner.  They followed up after the installation also.  I have had awful experiences with the local A/C companies and this company was not even close and had no problem driving down to Big Coppitt Key. The price of the new A/C was very reasonable too! You must use these guys! Nice clean cut guys too!"

"First, John Page (the design consultant) was there when promised. He was very knowledgeable & took the time to really explain things & their procedures to my Mother & I which made all the difference in making a decision on whom to go with on this journey... I call it a "journey" for these reasons: Out of the 3 other companies we called here in the Keys, not one of the seemed to care enough to spend the time & effort Ellington did, & when we asked about extending our warranties & maintenance etc. nobody had anything remotely close to offer compared to the Ellington "No Worries" program wheras they take care of EVERYTHING & the best part is there are ton of benifits no one else even offered w/no exclusions for 10 plus years. They also offer a 180 day money back guarantee in writing so for those reasons it was an easy choice! The installers were punctual, clean cut & very nice on top of truly demonstrating what was extremely important to us which was true craftsmanship. When making a purchase of this magnitude we know from past experience, it is not necesarily the equipment itself that is so important, it is the installation & setup that is even more important. After all work was done, a quality control audit was performed to assure us the machine was giving us all the efficiency it is supposed to & the ductwork was indeed installed per Johns drawings & sealed air tight as he promised. It passed with flying colors! My Mother & I would certainely recommend Ellington AC to anyone tired of a slick talking salesman that promises the world & then it does not go as planned... Probably the most professional company I have ever dealt with down here, Thank you so much!"

"My a/c wasn't working - we just moved into a home that had been vacant for almost 2 years.  I received quotes to fix the problem close to $3,000.00 and doesn't include labor (it was the motor to our a/c, HOME DEPOT was one of the quotes we received.  I called Mr. Llanes, and he sent Wally.  They came as expected and cleaned the coils and replaced the motor for 1/3 of what home depot and the other guys were quoting me.   3 weeks later,  the heater wasn't working and I called Llanes again and Wally came to service the unit on the same day and problem was fixed.  I would highly recommend these guys over and over again!"

Install Boiler questions, answered by experts

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.
