At Trademasters, we will guide you through the often-confusing process of selecting the right air conditioner for your needs and budget. Furthermore, we will factor in energy efficiency and aesthetics into the equation. And, we can help you find incentives on high-efficiency systems as well.



Air Conditioning System Maintenance Services

At Trademasters we offer preventive air conditioning maintenance plans for all types of residential cooling systems and units. Regularly scheduling AC system maintenance is a small, preventive step that can have a big impact on your home’s temperature consistency, performance, and overall energy efficiency and cost. It can also save you from the unplanned cost of an AC system malfunction.

Air Conditioning

Types of Air Conditioners

Air conditioners can be organized several ways, but the easiest is by type. All units can be divided into three distinct major types: single stage, two stage, and variable speed units.

Efficiency or SEER Rating

“SEER” is an abbreviation for “seasonal energy efficiency ratio.” The SEER (or efficiency) rating of an air conditioner refers to how much electricity the unit will use to keep you cool during a typical season. Higher numbers are better: the higher the SEER, the higher the efficiency is, and the less electricity the unit will consume.

Tonnage or Capacity

The “tonnage” of an air conditioner refers to the unit’s ability to remove heat from your home. The heat contained in buildings is measured in tons.

To give you an idea of what a ton of heat is, imagine a block of ice weighing one ton. One ton of heat is the amount of heat it would take to melt that block of ice in an hour. A ton of heat is also equivalent to 12,000 BTUs or 18,000 burning matches.

Residential air conditioners are made in sizes of 1.5 to 5 tons. They usually increase size in half-ton increments. The job of an air conditioning contractor is to determine what size (or tonnage) unit you need for your house. In this case, is it not a matter of “the more, the better.”

An oversized air conditioner will not remove the proper amount of moisture from the air. An undersized air conditioner will run constantly even at moderate temperatures and will not adequately condition the space. Since every home is unique, the best option is often to choose a two speed or variable unit. They work well even when slightly oversize.

Adding a variable speed furnace will help you remain dry as well as cool.

Single Speed Air Conditioners

Single speed air conditioners produce the same amount of heat removal all the time regardless of how hot and muggy it is outside. They are built to handle the hottest days of the year. While this is great in July, it means that they are larger than needed the rest of the time.

A good contractor will select a unit slightly smaller than what is needed for peak temperatures, since most of the time we do not see peak temperatures. Matching your unit to the temperatures you see most of the time will be more efficient and save you money.

Two Speed Air Conditioners

Two speed air conditioners have two distinct output capacities to better condition your home. These units can change the amount of cooling capacity they produce depending on how hot it is. Because they can slow down and run longer, they do a better job of removing moisture and providing enhanced comfort.

Variable Speed Air Conditioners

We recommend Variable Speed units for large homes. Instead of turning on and off all day to adjust the temperature, they run at a variable speed. They have 700 different outputs, which means they can accurately provide temperatures to within 1/10th of the degree you want. They provide exceptional comfort and moisture removal, with none of the hot and cold temperature swings typical to one and two speed units.

What our customers say:

I decided to go with Trademasters to replace my HVAC system after receiving a reasonable quote with no upselling. The service techs were punctual, professional, and proficient with the replacement and repairs. I will definitely consider using Trademasters for my future service/repair needs.

Trademasters did a great job on our first full HAVC/heating replacement, so we called Shane, and did it for our 2nd zone of two. So far doing great on first install over five years no issues, and second just a month ago.

I'm giving Trademasters five stars thanks to the five-star service we received. We recently had our ancient (and dead) HVAC unit replaced by this company and the quality of work was excellent! Also, the staff worked with a high level of professionalism.From our initial estimate meeting with Shane, I was very comfortable with his knowledge and was confident that they could do the job, which wasn't and easy one due to the age of our previous unit and the orientation of it. Shane gave a competitive quote and we decided on Trademasters largely due to his understanding of the situation and his experience.The staff worked from 7 am to 4 pm. It was an all-day job, but they got the work done earlier than previously estimated. Safety precautions were definitely taken and the technicians kept their masks on for the duration of the work, which alleviated any concerns. Once that air conditioning kicked it, relief was granted! Payment was easy as well and the office staff did a great job coordinating everything.Awesome service and highly recommended!

A Saturday air conditioner emergency was the reason for the call. I am so grateful to the technician that came and helped me out. He was very professional and knowledgeable and resolved my problem quickly. I owe him a big thanks for getting my AC working before the 100 degree days started!

We had our air conditioning go out unexpectedly on a weekend. I called first thing on a Saturday morning, and a technician came out later that same morning. He was able to get the system back working in the morning, but in the afternoon we heard a sound that indicated a further problem. We called and the technician came out again that same day, was able to do some additional diagnostics and determined that a bear in the motor had gone. While Trademasters was not able to fix it that day, they called first thing Monday morning and got a technician out to replace the motor. We have a regular service agreement and they only charged us for replacing the motor. I very much appreciate the expertise and professionalism of the technicians and prompt response from the support staff. I will definitely stay with Trademasters.

Trademasters' staff worked diligently to diagnose and solve my problem. They took extra care to be sure they were pursuing the most cost effective fix, including a "second opinion" visit at no charge. The staff were pleasant and professional, and the price was fair.

TradeMaster. From the first moment Shane Allen walked into my house and game me the estimate I know I can trust them. He Diddy push me to buy he did not called me to book his service instead he gave me space for me to think about it. Few days later after I spoke with my wife we decided to move forward with TradeMaster/Shane. Do you know how horrible is that during the summer you ac broke down! That’s exactly what happened to me. But after I booked the service they came next day and reemplace my units for a new one within 7 hours. Those people now how to get the job done professionally, fast and clean. Thank you so much for your amazing services and for faster response to my emails. You guys are the best. If you need this services don’t look no further I highly recommend it.

Our experience with Trademaster was a very welcome exceptional experience in replacing our HVAC system. We had contact with five representatives/technicians for the entire process. All were most professional in presenting the information we requested to the actual installation. With the average daily temperature reaching 90 degrees, the time for replacing our system was important. From the initial request for an estimate to the installation, Trademaster folks did it in a little less than three weeks. We certainly would recommend Tademaster Services to anyone needing HVAC or plumbing service

I recently had two service calls on the same day: one to do the yearly checkup on the HVAC and another to replace 2 toilet levers. AJ and Devon were technically savvy, professional, helpful and courteous. The company is lucky to have such outstanding employees.

We love Trademasters! Whether it was for planned improvements, like a new AC unit before the start of summer, or same-day repairs when the furnace died during the coldest days this winter, Trademasters has been wonderful to work with. Pricing is reasonable, with no upselling. We recommend them to everyone.

Excellent service from Trademasters and their outstanding technician Devon Houston. Devon showed up to install a new water heater but ended up dealing with the building’s issues that were complicating things. He did a fantastic job efficiently and professionally.

Gabriel was my technician and he was awesome. Very courteous, informative, and knowledgeable. He answered all my questions in layman's terms. The company was easy to deal with and gave me a courtesy call 10 minutes before my technician got there to let me know he was on his way. I highly recommend this company.

This week, we had our hot water heater replaced by Trademasters. We are long time clients of this company and, after pricing different providers for this installation, we decided to have them accomplish the job. Devon was our technician and I was so impressed, I sent a message to the company! Devon was not only very capable and efficient, but just such a great guy! He went way above and beyond helping me to clear the area around the hot water heater location, was kind and thoughtful and just a joy to have about for the duration of a pretty complicated job. I highly recommend Trademasters after years of dealing with this company, and I certainly recommend Devon Houston as one of their best representatives! My sincere thanks for a job well done!! ?

We had a total of 5 estimates for replacement of a heat pump and air handler for our townhouse. We found a wide range of prices, as much as $800 between them. We chose Trademasters, which was in the middle of that range, in part because they installed a furnace/ a/c in another home for us and have done fall and springs checks since then. They had always been easy to work with and schedule. That system is still working well. We had the townhouse checked out when we purchased it. David was the technician. He did a great job, explained everything about the heat pump and air handler, what potential problems we might have and the new R-ratings for coolant. The hardware was very dated (1985 and 2004), so when it had problems later, we had Trademastesr prepare an estimate. The estimator, Shane, like David, gave us cogent and detailed information and explained what he thought our best choices were. Chris (crew leader), Stephen, and Luis did the installation. They called ahead, were on time (early, even), watched out that the muddy outside did not come inside, even put up with the rambunctious puppy with grace. They worked straight through until the work was done and the house was heated, just before the unusual very cold spell that occurred in November 2019. Kudos to all of them. We would fully recommend Trademasters.

Trademasters provides some of the best service for a reasonable rate I know. Usually, you can’t trust plumbers or HVAC technicians but these guys are the real deal and the owner Dave is the kind of guy you hope to have as a neighbor!
