"We searched for a long time for a company to replace a current central A/C which was not particularly old, but the handler up in the attic was nearing the end of life so we had to replace the whole system. Speer seemed most knowledgeable, offered a product we were comfortable with (Amana) and were also professional and prompt. Of note we had a troublesome smart thermostat which required that they return multiple times to address - they did not consider the job done until this was fully operational. Overall we were very pleased, but the summer will tell!"

"We recently had the pleasure of hiring Dawson Mechanical to have a new Navien tankless water heater installed. This was a little more than a straightforward job since the water heater was being relocated from a utility closet to the garage which was about 20 feet away. From the time I made the first call to Dawson, I had a good feeling about this company. Dave came over within a few days on a Saturday to look the job over and give me an estimate. He is very knowledgeable and took the time to answer any questions we had. When the day came for the installation, a crew of 3 workmen arrived around 9:00 AM and did not stop until the job was finished around 5:00 PM. They did an excellent job, were very good about keeping everything clean and neat, and the workmanship was top notch. In short, we were very happy with everything and would not hesitate to use Dawson for our future plumbing/HVAC needs."

"ABCastello HVAC removed old A/C inside and outside units which were 25 years old from my 2700 sq feet 2 store colonial brick face house. Old units were replaced with new and more efficient units - TRANE 4 ton two stage SEER 17+ ECONET (condenser model RA-1748-AJ2CB, air handler model RH-2T-4821-MEACJA and communicating module Econet STAT model RETS-T601-SYS). Excellent work quality! Fast response! Very reasonable price quote for 10 years parts warranty and 5 years labor and service warranty! Honest and hard working person! All work was done in a couple of days (including old unit removal)! I am very happy and a very satisfied customer of his service for life!!! A+++++"

"The HVAC tech Jay was everything a homeowner could wish for in a contractor. He called 30 minutes before he was scheduled to arrive to say he was on the way, he was on time, friendly as can be & extremely knowledgeable, hard working & honest. He tried everything he could think of to repair the condenser before telling us it needed to be replaced. He didnâ t do what others would and just give us a price, he gave us options as far as equipment was concerned & the different price points. The folks at AAA HVAC went above and beyond with our system. What started out as a simple Condenser replacement turned out to be needing an entirely new HVAC system because the old system was completely mismatched & undersized for the size of the house & condenser we have, causing all kinds of problems. Including our original condenser dying in under 5 years. Long story shorter, it was an unexpected financial hit and they not only inspected, quoted & replaced everything within a day, they worked with me on financing. Jay even returned the very next day to fill out the invoice with all model & serial numbers that was requested by the manufacturers for any future warranty repairs, just registering the equipment on line was not good enough. I would without a secondâ s hesitation recommend AAA HVAC & Jay. I look forward to working with them on all our Future HVAC needs."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"Eric & Dante went above & beyond to make our heater work during this brutal single digit weather. Diagnosing the issues is one after the another but they were able to make it happen. Their company is really prompt, very professional and very fair pricing. Eric is even available after business hours to answer technical issues. You will rarely get this type of pros."

Heating and Air Conditioning questions, answered by experts

HVAC companies may charge an hourly rate or a flat fee. Hourly rates typically range from $100 to $250 per hour, with an average around $175. Some contractors charge a flat fee for specific services, such as an inspection, which can cost between $150 and $500. The total cost of an HVAC service is influenced by several factors, including: the urgency of the service (emergency repairs after hours or on holidays cost more), the time of year, the type, size, and brand of your HVAC system, the specific repair needed, and whether you have a service contract.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

A new air conditioner capacitor will cost less than replacing the entire air conditioner system. While a capacitor itself will cost between $8 and $25, paying a professional to replace an AC capacitor will cost $180 on average. It’s not safe to replace an air conditioner capacitor on your own. 

You will only need to refill your AC with refrigerant if it has a leak. Otherwise, a modern, well-maintained AC will most likely never need a recharge. You may notice a leak in an older system if your bills are higher, you hear a hissing sound, or if the air is blowing out hot.

Yes, having mismatched evaporator and condenser coils in your AC system can lead to serious issues. For instance, it can result in higher monthly energy costs as the system runs longer to compensate for the mismatch. This mismatch can also put extra stress on the system, compromising its efficiency and longevity. 

Along with that, mismatched coils can lead to higher temperatures and humidity levels in the home. What’s more, using coils of different sizes may violate the manufacturer's warranty, as they are designed to work synergistically, and any mismatch could lead to repairs and system failure.
