8 of the Most Common Air Conditioner Repairs in the Denver Metro Area

Tuesday, July 10th, 2018

8 of the Most Common Air Conditioner Repairs in the Denver Metro AreaIn the scorching heat of summer, your air conditioner isn’t a luxury, it’s a necessity. If it stops working efficiently, or doesn’t work at all, you’ll need to take action immediately, before the sweltering heat leaves you feeling ragged and miserable.

Here are eight common reasons why your air conditioner may suddenly stop functioning …

1. Frozen evaporator coils

The evaporator is installed inside the indoor air handler, and its job is to extract heat from inside the home for release into the atmosphere outside. Unfortunately, if air flow over the evaporator coils is inadequate they can rapidly freeze up, making it impossible for your air conditioner to keep working.

In most instances, the cause of frozen evaporator coils is a dirty air filter. You may need a technician to check to make sure, but if you replace your air filters frequently this is a problem you can avoid.

2. Leaking refrigerant

Your air conditioner requires adequate supplies of refrigerant to remove unwanted heat from your home. Unfortunately, small leaks can develop at various points in the refrigerant system, and if that happens your air conditioner will gradually lose its capacity to cool.

This problem is extremely common, but a trained technician can find and repair these leaks and recharge the refrigerant to the proper level.

3. Poor drainage

The drainage system, including the drain pan and drain lines, is designed to divert moisture that collects while your air conditioner is in operation. If clogging occurs water may back up into the air conditioning system and severely damage its components.

But here’s the good news. For a trained expert, clogs in the drainage system are simple to detect and just as simple to clean out.

4. Broken or malfunctioning compressor fan

Compressor fans are found in the air conditioner’s outdoor unit. They assist in the heat transfer process and also help keep the compressor cool. If they break or suffer a reduced spin rate the compressor may overheat and burn out, and indoor temperatures will slowly rise as heat transfer is disrupted.

Ideally, sputtering compressor fans should be replaced or repaired before they stop working completely, but either way a quick repair is required to prevent catastrophic equipment failure.

5. Frozen condenser coils

Poor air flow in an HVAC system may cause the condenser coils on the outdoor unit to ice over, making it impossible for them to function effectively (they release heat outside that was removed from indoors).

Dirty air filters or blockages in the duct system are common reasons for condenser coil freezing, but regardless of the cause a trained expert can diagnose the problem and fix it.

6. Troubles with the wiring

Bad wiring work plagues many heating and air conditioning installations, although it may take a few years for electrical problems to develop. Over time even wiring that was installed properly can become frayed, and terminal corrosion is another complication that can cause troubles in your HVAC electrical system.

Only an expert can uncover and repair bad wiring work—but if you suspect bad wiring is to blame for your air conditioner’s poor performance, don’t call the company that handled the original installation.

7. Faulty thermostat

Thermostats tend to break down after years of heavy use, especially if they are older models. Thermostat batteries also need to be changed from time to time, and if your thermostat has gone dead that is something you should try before you call a repair and maintenance technician.

Thermostat failure might be the cause if your HVAC system refuses to start, or shuts off quickly (or won’t shut off at all) once it does. If the technician who inspects your system confirms thermostat failure, you should consider upgrading to a programmable thermostat with Wi-Fi capability, they can be real money savers.

8. Inadequate maintenance

Like clockwork, HVAC equipment should be inspected, tested and tuned before the start of each heating and cooling season. If you are lax about maintenance you’ll be setting your HVAC system up for failure, but if you haven’t been diligent about maintenance before it is never too late to start.

Cold Spots in Your Home? Here are 4 Ways to Fix this Issue

Thursday, October 2nd, 2014

1. The 2-Stage Furnace

With the capability to switch between two speeds as needed, automatically, a 2-stage heating system delivers heat over a longer period—providing more consistent Cold spots in your hometemperatures throughout you home. Two-stage heating equipment also offers another major advantage: it can save you energy and money on operating costs long term. This isn’t true you’re still using the same amount of energy to heat as a single stage model. The 2-stage really only improves comfort.

Two-stage furnaces provide these benefits because they allow gradual stepping up and down of the home’s heating as needed—although it runs on “low” speed most of the time. In contrast, a standard furnace has just one speed–essentially running on “high” all the time, otherwise it’s off. All of the “on-and-off” cycling that single-stage heating systems must do tends to produce the cold spots and cold blasts of air that you’re noticing in your home. Cycling the heat on and off constantly also wears components out. A running furnace is easy on the furnace. It’s the stopping and starting that increases failures and breakdowns. A 2-stage furnace may even make your home quieter as a standard one-speed furnace is noisy.

2. Zoning Systems

A zoned heating system, or zoning system, divides your home into a number of distinct climate zones. This allows you to set unique temperatures in each zone of your house. You’ll be able to control your home’s cooling in exactly the same way, come summer, if you have central air conditioning.

To create a zoning system, an experienced Denver-area HVAC contractor will divide your home into zones according to your needs and the home’s layout. This is done by strategically placing a set of dampers in your duct system. The dampers route the conditioned air to each climate zone as needed to maintain your preferred temperature. By using energy wisely and only where needed, the system becomes more intelligent and saves you energy dollars.

3. Variable Speed Blower

This is an advanced design feature to look for when choosing your next heating system–or it can be added to your existing system as an upgrade. Ultra-efficient variable speed blower motors use just a fraction of the power that a typical blower requires. Variable speeds enable the blower to better mix the air inside your home–and to efficiently continue working even when the furnace is not on. This continued air circulation evens out heat distribution and provides healthier IAQ (indoor air quality) as air passes through the filter more times. You also get consistent temperatures, greater home comfort and energy savings–all at the same time.

4. Duct Sealing and Balancing Airflow

The duct system may be largely out of sight and out of mind in your house, but this allows hidden leaks to go unnoticed. Over time, leaks enlarge and can cost homeowners and extra one-third on their monthly home heating and cooling bills, as EnergyStar.gov points out. Get a duct inspection and your local home comfort contractor can seal the duct system to drastically limit heat loss—and get the warmed (or cooled) air from your HVAC equipment to all the areas of your home. Your HVAC contractor may also recommend minor duct retrofitting, like adding supply or (more commonly) return registers to certain rooms, so that air flows evenly in and out for consistent comfort.

Self-Service Air Flow Testing in your Denver Home

To determine whether air is circulating throughout your home properly, just turn on your blower, switching it from the normal “auto” position to the continuously “on” setting. If you notice a difference in comfort level simply by running the fan continuously, you could benefit greatly by one or more of these four fixes. Note: Using this shortcut as a long-term fix can increase your electric bill by about $40 per month—so talk to your local home comfort expert to help you with one of the above permanent solutions.

Should You Repair or Replace Your Air Conditioner? There are 3 Main Factors to Consider

Monday, August 4th, 2014

Should You Repair or Replace Your Air Conditioner?When your air conditioner stops working, your main question should be whether to repair the unit or replace it. Repairing the unit will almost definitely cost less now, but it may be more cost effective in the long run to replace it. The three main factors to consider are your air conditioner’s life expectancy, energy efficiency, and overall condition.

Life Expectancy

The typical air conditioner only lasts about 12 to 15 years. Although you can repair air conditioner units that are reaching the end of their life expectancy, the parts may be difficult to find and the repairs might only help you get another year or two out of the unit.

Energy Efficiency

Newer air conditioners are more energy efficient than older ones, and you can save yourself a lot of money with a new unit. The main number you want to be looking for is the S.E.E.R. (seasonal energy efficiency ratio), which is a measure of your air conditioners energy efficiency. Today’s minimum efficiency level is 13 SEER Units made just 7-8 yrs. ago may have a 10 SEER rating. If you have an air conditioner with a low S.E.E.R., it may be more cost effective in the long run to replace it with a newer and more energy efficient unit.

Overall Condition

Regardless of your air conditioner’s age and energy efficiency, you should also consider its condition. If you have a unit that has been plagued with mechanical issues and breakdowns, you may want to replace it even if it is relatively new and energy efficient. On the other hand, a high quality unit from a reputable brand may last a long time with only minor repairs.

Making Your Decision

Rather than suffering through a hot summer with a broken air conditioner, get a reputable company in the Denver metro area to give you quotes on repair and replacement costs for your air conditioner and talk you through the options. In our experience, it is often best to go ahead and replace air conditioner units that have failed in even one of the three criteria. You can get a unit now to take advantage of this year’s prices and get the rebates that may run out before next summer rolls around.

It’s Time to Get Your A/C Ready for Summer by Scheduling Your Annual Air Conditioner Maintenance

Tuesday, April 8th, 2014

It’s Time to Get Your A/C Ready for Summer by Scheduling Your Annual Air Conditioner MaintenanceWith Daylight Savings time behind us, days are getting longer and temperatures will be getting warmer. Before you know it, you’ll be programming your Air Conditioner to keep your home temperate. Yearly Air Conditioner maintenance can improve the performance of your Air Conditioner and prolong its lifespan so that you stay comfortable in your home no matter the temperature outside.

Benefits of Annual Air Conditioner Maintenance

When Air Conditioning units are not regularly serviced, dirt and debris build up inside. These contaminants hurt performance, so that your Air Conditioner has to work harder (and consume more energy) to cool the house. You’ll notice increased energy consumption, higher utility prices, and lowered unit performance when this happens. The fee that you’ll pay for annual maintenance is offset by the lower utility bills and increased comfort you’ll realize when units are working at their best.

Annual servicing removes dirt and debris that clog your air conditioning unit, negatively impact the unit’s performance and affect the indoor air quality in your home. Replacing furnace filters lowers unit energy consumption and improves performance by as much as 5 to 15 percent. During a regular maintenance visit your technician can also identify any potential problems that may cause a future breakdown. This allows you to budget accordingly for a new unit or repair as your existing Air Conditioner ages, and can help you avoid the stress of going without air conditioning when an old, neglected unit breaks down.

Maintenance tips

In a typical maintenance visit, your technician will inspect the unit and all its parts, clean the outdoor coil, inspect your system’s electrical components and connections, check the refrigerant levels, and make any tune-ups or adjustments necessary. Indoor Air Quality charges $119 for Air Conditioner maintenance appointments. This includes unit cleaning, inspection for wear and tear, checking of operation and recommendations of any needed parts and repairs. A reputable technician will have good working knowledge of all of the major Air Conditioner brands, such as Rheem, and will be able to properly service both new and older models.

Spring is the perfect time to have your Air Conditioner unit serviced, as any replacements or repairs can be made before the weather gets hot. In the worst case, if you wait until the heat of the Denver summer to have your unit serviced, you may end up going without an Air Conditioner while the technician repairs any problems.
