Sometimes, when we go out to a home, we find more than one problem with a condenser and the AC system as a whole.

If your system is more than 10 years old or we find multiple issues, we will recommend an AC replacement. And although replacing an entire AC system can be pricey, it’s often worth the money in the long run.

Think about it: there are a lot of parts in your AC system. If we replace several belts, a coil, and resize a duct, you still have components in your system that are likely to fail soon. Oftentimes, the cost of several replacements adds up to a significant amount of money you could have put toward a totally new system. There are also several cost-advantages to owning a brand-new AC system that include energy efficiency savings and rebates. This is why, when we find more than three significant issues- and especially if you have a system that uses R-22- we recommend an AC replacement.

3 Reasons to Upgrade to John Moore Lifetime Equipment.

  1. The Lifetime Unit Replacement Limited Warranty is valid for as long as the original purchaser owns his/her home. If the Lifetime air conditioner unit fails in use at the original registered homeowner’s residence, the repair will be provided at no charge.
  2. Each John Moore Lifetime unit is upgraded with top-of-the-line parts to meet the harsh demands of the Houston climate.
  3. Protect yourself against higher future replacement costs due to inflation and higher costs of living.

*Exclusions may apply. Water heater, HVAC, and Breaker Box labor warranties on select equipment. Call for details.

What’s Included in John Moore’s Air Conditioning Replacement?

Before we replace your AC system, we run a heat load calculation to determine proper size, take measurements, and present you with the best options for everything: a new condenser, new duct work, new condensate drain lines, and any other options such as zone systems, UV light disinfectors, air purifiers and anything that would apply to your home’s AC system and air quality. We discuss your budget, and look over rebate options, tax credits, energy efficiency, and of course, price, to find the ideal system for your home. And because a new AC system is one of the most expensive things most people pay for (next to a car and your home itself), we go over our financing options.

After that, we work with you to find the best time to get to work. If we start sometime in the morning, we can usually finish replacing your entire AC system that same day. And if it’s an emergency, like your AC goes out in the middle of summer, we will supply you with portable cooling units until we can get to your home to replace your system.

John Moore’s HVAC Replacement Process.

The first thing we do when we show up to install is put down a drop cloth and make sure every technician has their shoes covered so we don’t track mud or dirt into your home. We may request to move furniture or valuable items so we don’t accidently bump into, scratch, or break anything. And if you have pets, we may ask for you to keep them in a room or at the neighbors to minimize the chances of any accidents (we do not want to accidently run into your cat or dog while carrying a furnace). We measure a second time just to make sure everything will fit through doorways and tight spaces. Then we begin breaking down your old AC system. We load all of your old equipment into a truck to take back and recycle.

After that, we get to work installing your new system. There will be a lot of moving of large equipment and some loud noises as we fabricate parts, drill units into place, and move around your attic. We may also lay extra boards down in your attic so we don’t step through a ceiling. Then we connect the refrigerant lines and attach your new system to your home’s power source. And then, we turn it on.

Included in every AC replacement is a final, whole-home air balance. We test every air register in your home to make sure it’s delivering the right amount of air at the appropriate temperature. We may go back into your attic to adjust dampers until everything is just right. After that, we take you on a tour of your new system, provide you with maintenance tips, and let you know to call us if you need any adjustments or encounter any issues.

AC Condenser Repair

Why is My Air Conditioner Not Cooling?

Condensers & Condenser Repair

What's a Condenser?

Chances are you’ve noticed one or two large, metal boxes outside of your home. Those are your AC system’s condensers. Inside of the condenser is your refrigerant, a compressor, a condenser coil, a capacitor, an electromagnet, a fan, some relay switches, and other electronic and mechanical components that vary from system to system. As we discussed in the Basic Operations section, your condenser is where a lot of the magic happens; it’s where the refrigerant is compressed and pumped to the evaporator coil, and where the refrigerant returns to release heat.

What Should I Look For?

If you notice that your home isn’t cooling or is taking a long time to cool, it could be a condenser issue. If you go outside and notice any leaks around your condenser or strange noises when the fan turns on, you should call an AC technician immediately.

What Causes Condensers to Malfunction or Fail?

One of the primary suspects is electricity, or lack thereof. The first thing we do before we even open up the condenser is make sure it’s getting electricity. If we check the breaker box and notice a problem, we will have to refer an electrician to solve that issue first.

The majority of issues we find in condensers are refrigerant leaks, broken capacitors, broken belts, faulty relay switches, motor failure, or a faulty or broken condenser coil. There are a number of other issues, but these are the most common ones.

How We Fix It.

After ensuring your condenser is being supplied with electricity, we take into account any signs you may have noticed. Because refrigerant goes between a gas and a liquid state, refrigerant leaks aren’t always noticeable. So the next thing we do is use an electronic leak detector to find out if your refrigerant is leaking and locate the leak. If we do find a leak, we can replace the pipe or coil that’s leaking and recharge your system.

NOTE ON R-22 REFRIGERANT

r22If your system uses R-22 refrigerant, keep in mind that R-22 is being phased out by 2020. That means if your refrigerant leaks after the year 2020, you will have to replace your entire system. If we are inspecting a system that uses R-22 refrigerant, we will give you options to replace your AC system with a new one that uses R-410a. We strongly recommend upgrading your system before the 2020 phase out so you can budget, plan ahead, and not be surprised with a large expenditure in the near future.

After we determine whether or not a refrigerant leak is causing your condenser to malfunction, we will run some other diagnostics to test the capacitor, belts, relay switches, condenser coil, and fan motor. We will then provide options for any parts that need to be replaced in your condenser.

AC Drain Line Leak

Why is My Air Conditioner Leaking Water?

Condensate Drain Line Repair

What’s a Condensate Drain Line?

As we mentioned in the Basic Operation section, your AC system has an evaporator coil in your attic that get’s really cold, usually as low as 40 degrees fahrenheit. As this coil cools the warm air moving past it, it produces condensation. Underneath the evaporator coil is a drain pan that catches condensation as it falls. The condensation is then directed through an insulated ¾ inch PVC pipe that ties into a drain line underneath a sink in your home. This ¾ inch PVC drain is your condensate drain line.

What Should I Look For?

If you notice water marks on your ceiling, it could mean one of two things:

  1. You have horizontal pipes that are leaking or,
  2. Your condensate drain line is backed up or sweating.

We won’t know what’s causing the water to drip to your ceiling until we go to your home. If it’s a leaking pipe, then we would refer a plumber to do a horizontal or whole-home repipe. But if it’s a sweating or backed up condensate drain line, a John Moore AC technician can solve the problem with a condensate drain line repair.

As time passes, algae can start growing or rust from the evaporator coil can find its way inside of your condensate drain line. Rust, algae, or a combination of both get stuck at the connection point underneath your sink, and water begins to back up, causing your drain pan to overflow. Luckily, there’s a secondary, emergency condensate drain line that can prevent your drain pan from overflowing for some time. The draining point of your emergency condensate drain line can be found somewhere underneath your roof soffits, usually above a window. If you see this pipe leaking water, you should call an AC technician to unclog your condensate drain line and empty your drain pan.

What Causes Condensate Drain Line Leaks?

So what causes the water marks on your ceiling? It could be two things:

  1. Your drain pan could be overflowing with water or,
  2. The insulation around your condensate drain line has deteriorated or been chewed through by rodents in your attic, causing the drain line itself to sweat.

To identify the specific cause, a John Moore technician will inspect all the components of your AC system including the evaporator coil, drain pan, and drain lines.

How We Fix It.

If your condensate drain line is backed up, we clear the line from the connection point under your sink and inspect the water to determine whether the culprit is algae, rust, or both. If it’s rust, we will recommend replacing the evaporator coil so the same blockage doesn’t happen again anytime soon. If we find algae, we will recommend using Plumbers’ Formula 6, a special plumbers formula you can put into the condensate drain line service port every month or so to prevent algae build-up. From there, we empty and clean the drain pan, run clean water through the condensate drain line to clean it out, and clear out the emergency condensate drain line with a wet vac.

If we inspect your condensate drain line and find that a lack of insulation is causing it to sweat water, we will look for signs of rodent bites and deterioration to determine the cause. More than likely, the insulation has deteriorated over time, but it’s also not uncommon for rodents to live in attics and chew on the insulation around the pipe. In either case, John Moore AC technicians can replace this insulation. But if we do determine that rodents chewed through the insulation, we will recommend and refer pest control to inspect your attic, rid it of all rodents, and take measures to prevent the problem from happening again.

If your ceiling or sheetrock incurred damage from a condensate drain line issue, our Renovation and Remodeling team can provide expert ceiling / drywall repair and painting services to make it look like the damage never happened.

Duct System

Why are Some rooms Cool and Others Hot?

Air Duct Design and Air Balancing

What is Air Duct Design and Air Balancing?

Air Duct Design is the process of resizing and replacing air ducts in your home. Air Balancing is when we make sure a given air register or all air registers in your home are releasing the correct amount of air at the right temperature.

What Should I Look For?

If you feel like the temperature and comfort level of the air in your home is inconsistent from room to room, then your air ducts may need to be resized or balanced.

What Causes Unbalanced Air Distribution?

Several things can cause inefficient ductwork or unbalanced air distribution:

  1. Your Air Duct has been pierced or crushed. It’s not uncommon for homeowners to accidently crush an air duct with a storage box or for another service person, like a cable guy, to accidentally lay on the duct work.
  2. Your air ducts were built too small to begin with.
  3. The tonnage of your HVAC system is too small or
  4. There is extra heat that was unaccounted for in the initial sizing of your equipment. Say, for instance, you add a flat screen TV, a computer, and game consoles into a room of your home. All of these devices will create extra heat in your room that wasn’t accounted for when the branch of ductwork leading to that room was sized.

How We Fix It.

To fix uneven air distribution in your home, the first thing we do is conduct a heat load calculation. Based on factors like the size of your home, air leaks, heat producing electronics, and plants, we determine the ideal tonnage of your system. We then check the tonnage of your AC system, and if it’s too small, we will recommend a replacement of your entire AC system.

After we check the tonnage of your system, we will make sure your air ducts are intact. If we find any pierced, crushed, or undersized air ducts, we will determine what the cause was. If we determine rodents chewed through your duct work, we will patch up the holes and refer pest control to rid your home of rodents so it doesn’t happen again. If we determine your ductwork is undersized, we will recommend resizing them.

We will also go from air register to air register to measure the temperature of the air coming out versus the temperature your thermostat is set to. Generally, the air coming out of each register should be 20 degrees below the temperature your thermostat is set to. If the air coming out of a register is not 20 degrees below your thermostat’s setting, we will recommend an air balance. To balance the air in your home, we install various dampers to collars where your air ducts attach to the air plenum. We will then adjust each damper until the temperature of the room in question is what it should be.

If you live in a large, two-story home, we can also install a zone system with electronic dampers that can balance the air room by room or story by story.
