Job Details

Location of Job: Annandale, VA
When: May 24, 2018
Service Category: Residential
Services Performed: Air Conditioner Evaporator Fan Motor Repair & Replacement
Brief Explanation

What Was The Main Issue Here?

We came out to a customer who was within the Annandale area regarding their air conditioning unit which was experiencing some issues.

Over the phone, they mentioned to us that their air conditioner wasn't keeping the air as cold as it was normally capable of doing.

They also mentioned that despite constantly adjusting and readjusting their thermostat that they were experiencing little to no change in regards to the air conditioner working as it should have.

Add into the mix how their electric bill was up severely from what it normally was since they kept trying to readjust the temperature and soon became too much.

Once we arrived and conducted an in-depth diagnostic of their air conditioner, we were eventually able to determine that the main culprit which was responsible for all their issues was the evaporator fan motor.

While we initially tried to see what could be done to spare the part, it was soon revealed that we would need to get them a new one entirely for their air conditioner.

Thankfully though, after a quick trip to our nearby HVAC supplier, we were able to get a suitable replacement for them and get their air conditioner back up and running cool again.

Location of Job: Annandale, VA
When: May 18, 2018
Service Category: Residential
Services Performed: Gas Water Heater Repair
Brief Explanation

Why Were We Chosen For This?

One of the first reasons what we were chosen to help fix up this residential gas water heaters is that we are one of Annandale's top-tier companies when it comes to quality HVAC service that's local as well as reliable.

Additionally, the customer which we worked with for this project loved the fact that we provide a 6-Month, Hassle-Free Warranty on all of our parts and services once we come out.

What Was The Issue Specifically?

Once we conducted an in-depth diagnostic of the this customer's gas water heater, we were able to deduct that there were two main actions which needed to be conducted:

1 - Replacing the unit's Thermocouple,

And 2 - Putting in a brand new Burner Kit into the unit.

After both of these we conducted and resolved, the gas water heater was back up and running once more.

Gas water heaters are fairly different than newer electric water heaters.

Thankfully for our customers though, we're able to service and repair both types effectively and efficiently.

Job Details

Location of Job: Annandale, VA
When: May 2, 2018
Service Category: Residential
Services Performed: Furnace Installation, Along with Evaporator Coil, Water Heater, & New Duct Work.
Brief Explanation

Did We Only Work On A Furnace?

A local Annandale customer came into contact with us recently in regards to getting a serious overhaul done to their HVAC system.

The main project which we completed for this customer was in installing a new high-efficiency furnace for them.

Specifically, they got a new Amana which is a solid, top-of-the-line brand name in terms of furnaces.

Additionally, we also installed an evaporator coil, a high-efficiency Rheem water heater, a humidifier and also a whole new ductwork system.

Needless to say that this customer definitely felt like upgrading their overall HVAC system and we were just the people for the job for them.

What Made This Customer So Satisfied?

One of the main compliments which we received from this customer in regards to this project was in how we were able to provide quality installation services that fit within their time frame.

Furthermore, they admired our straightforwardness.

We never tried to hide from numbers or price estimates when we're out on the job giving estimates that are centered around our customer's need.

Some other services like to talk about price, or tend to be excessively vague about installation fees. Not us.

Here at Kelvin HVAC, we value transparency as much as our customers do, and we never try to bend the truth just to get an extra job done that' s outside of someone's budget.

Location of Job: Annandale, VA
When: Apr 25, 2018
Service Category: Residential
Services Performed: Carrier AC Condenser Installation
Brief Explanation

What Type Of AC Was This?

A customer local to the Annandale area had us out to install their new Comfort series Carrier Air Conditioner.

Overall, this installation was fairly straightforward and to the point.

We've done many installations over the years just like this one and we know how to do things thoroughly as well as efficiently.

Are Carrier ACs Any Good?

These specific models are often able to run quieter than the common hair dryer, which makes things a lot easier on the ears as a whole.

All current Carrier models follow the energy-efficient standards set forth by the government in an effort to reduce carbon emissions and also to lower energy costs across the board.

Carrier Air Conditioners are some of the most robust AC units on the market. Their average air conditioner lasts anywhere between 12-15+ years while some of their gas furnaces have been known to last 20-25 years. That's nearly a quarter of a century!

Interestingly enough, the Carrier brand has been around since 1902, which is actually 10 years earlier than sliced bread was invented. Go figure.

Location of Job: Annandale, VA
When: Apr 26, 2018
Service Category: Residential
Services Performed: Air Conditioning Service and Assessment
Brief Explanation

What Was This Job Like?

A customer gave us a call in regards to their air conditioning unit not properly cooling as much or as efficiently as it should have been.

The specific unit which was giving this customer some trouble was on top of the roof of their condo building.

After we conducted our in-depth diagnostic, we were able to correctly ascertain that our customer's unit was low on refrigerant due to a system leak.

Once we found the main source of the leak, we were able to repair the adjacent sections around it and then charged the whole system back up with some nice, fresh refrigerant.

All in all, our service for this customer's air conditioner was very fast and efficient, and they were extremely thrilled that we got their Air Conditioner back to its proper working order.

Location of Job: Annandale, Virginia
When: Apr 11, 2018
Service Category: Residential
Services Performed: HVAC Cleaning
Brief Explanation

A recent customer got into contact with us in regards to their AC unit giving them some troubles.

Upon receiving their call, we set up a personalized appointment for them that best fit their schedule and then went right to work.

Why's A Clean Evaporator Coil So Important?

Once we'd completed our initial diagnostic of the unit and had given it a proper look over, it became obviously apparent that the condensation build-up was affecting the unit's proper systems of operation.

Condensation buildup is fairly common in AC units, especially around the evaporator coil but if there's too much of it or if your system isn't correctly adjusted at the right levels, then it can clog up the unit.

This will then prevent it from working properly and even produce ideal conditions for mold buildup and distribution from within it.

Additionally, a dirty evaporator coil can lead to other various amounts of troubles such as excessive energy use, more dramatic temperatures and pressure buildup, improper heat absorption, and cooling capabilities, and the opportunity for frost and ice to build up.

After we cleaned out all the excess condensation buildup, we made sure that everything else was in its proper working order and returned the unit back to its ideal working order.

Location of Job: Annandale, VA
When: Apr 2, 2018
Service Category: Residential
Services Performed: Mold Removal and Unit Cleaning
Brief Explanation

When Was This AC Unit Last Inspected?

Who knows! Apparently, we were the first ones to go out of our way and have a look at this hard to reach ceiling unit.

You can tell by the Before pictures that what we found wasn't very pretty.

What Was This AC Unit Repair Like?

What started as a routine service inspection in a condominium quickly turned into a priority mold removal and cleaning.

We then found that a massive amount of mold had permeated the ceiling AC unit and likely hadn't been cleaned in years.

We went to work ASAP once we saw this and were determined to eliminate any traces of the hidden nuisance.

Once we finished cleaning up all of the affected mold, we then serviced the unit as initially planned.

Everything was then back to its regular working order, and much cleaner and safer than it was prior to our expert oversight and highly-detailed oriented inspections.
