Does Rain Affect My Air Conditioning Unit?

If you have ever watched rain pouring down into your yard and wondered if it was doing damage to the inside of your AC unit, you are not alone!

Many homeowners are concerned that their AC unit may get damaged by weather. When it comes to rain there really should be no issue, however, this is not the case with all weather occurrences.

Does Rain Damage my AC Unit?

Your AC unit is made up of aluminum, copper and/or other metals or metal alloys. This allows your AC unit to resist damage due to excess water from rain. These pieces are created in a way that they are protected and sealed so that your home can go on and keep on cooling even when it’s pouring outside.

So the answer to the rain question, no, it is not likely that rain will damage you AC unit. However, other weather occurrences may not be as kind to your AC unit.

What Weather Can do Damage to My AC System?

There are some types of weather that can cause damage to your AC system.

Flooding – While heavy rain might not do damage, deep standing water can. Standing water that is around or above 15 inches can get into the moving parts in your AC unit. This can cause damage to your electrical components.  If your area suffers from flooding,  be sure to have your unit check out by an HVAC professional.

Storms – If you have bad storms that include hail or high wind this can cause debris to get inside your outdoors AC unit. This debris can then get into the different parts of your AC unit. If you suspect that damage has occurred after a storm, turn off your AC unit and call for maintenance.

Winter Snow and Ice – If  you are concerned about corrosion from winter moisture getting into your system you may want to choose to cover your AC system. For the most part, snow and ice will not do damage to your system however on the odd occasion moisture may get trapped and caused corrosion.

What to Do in Case of a Bad Storm

We are lucky here in Denver that we don’t get too many wild weather events. Hail and high winds are two of our biggest issues through the spring and summer months. If Denver suffers from a bad storm and you are concerned that damage has been done to your AC system be sure to switch it off first.

What Is HVAC Zoning?

If you are looking for an efficient and effective way to heat and cool your home, you may be looking at a new HVAC system. If you have a system that is over 10 years old, buying a new system can be a great investment. Every 5 – 10 years technology improves and new systems are becoming more and more efficient.

HVAC zoning is a great way to effectively heat and cool your home while getting the most from your energy budget. So what is HVAC Zoning and how can it help keep your home and wallet comfortable.

What is HVAC Zoning?

HVAC Zoning is perfect for large or multi-level homes. These HVAC systems use different units or different thermostats to heat and cool only the spaces you need when you need comfort the most.

Zoned systems break your home up into different zones or areas. Each of these zones is then controlled by a separate thermostat. You may have different zones for your living and sleeping areas, or you may have an upstairs and downstairs zone. No matter how you decide to zone your home, zoning will allow you to direct hot or cold air only where you need it.

The system itself works through controlled dampers. These dampers are in your ductwork and work to control the flow of air throughout your home.

Your thermostats are the second parts of the zoned system. You can adjust each zone individually which then sends a message to the dampers on how you want the air distributed through your home at any one particular time.

Why Install a Zoned HVAC Systems?

Zoned HVAC systems are very efficient due to the fact that you can control exactly what is happening in your home, turning the heating and cooling off as you need it.

With a zoned system you can also gain more even temperature distribution. Zoned systems can help eliminate hold and cold spots in your home. Quite often in two story homes your main level will be comfortable but your upstairs will be either too hot or too cold. Different zones can help combat this all too familiar problem.

Another great advantage to Zoned systems is allowing flexibility for different comfort levels. If you have family members that get colder a whole lot easier than you do, you can relax in the different zones, enjoying different temperatures.

The benefits of yearly maintenance on your AC system far outweighs the small cost of the appointment.
  2. Provide Shade for Your System - The Colorado sun can be brutal. If your AC unit is sitting out in the blazing sun it is going to have to work a lot harder to produce the cool air to keep your home comfortable. You can’t move where your AC unit sits but you can build a little shade shelter for your unit. You can use old fence pailings or wood to create a shade wall around your unit.

Spring AC Maintenance

Spring is here in Denver, the trees are blooming and the mountain snow is melting. Spring is a great time to get out and experience all that Colorado has to offer. It is also a great time to take care of some maintenance when it comes to your AC system.

Preparing your AC system before the hot weather arrives is a great idea. This will help your system run more efficiently and effectively. It can also help keep the air inside your home cleaner.

Spring AC Maintenance Tips

If you did not have a full maintenance inspection or tune-up completed on your AC system last fall, that is a great place to start. Having an expert go over your AC with a fine tooth comb will make sure it is safe and ready to handle the summer heat.

If you have already had a tune-up completed there are a few things you can do yourself to make sure your system is ready to go.

  • Change Your Filters - Ideally, this should happen every 2-3 months, however, you may need to do it more if you have pets in the house. Also, if you have allergies, changing the filter more often can help.
  • Change the Batteries in Your Thermostat - Spring is a great time to make sure the batteries in your thermostat are in good condition and charged.
  • Hose off Your Outside Unit - Clean off any dirt or debris that has built up around your outside unit. You can use your garden hose to wash most of this off.
  • Program Your Thermostat - If you have a programmable thermostat now is a great time to set a summer schedule. If you don’t have a programmable thermostat, you may want to think about switching to one. The ability to program when your AC runs can save you money.
  • Drainage - Make sure your system can drain properly. If the drainage hole is clogged this could lead to bigger issues.
  • Turn it On - Before the really hot days it, switch on your AC. Run it for 20-30 minutes to make sure cold air is coming from the vents. If the air coming out is not cooled or your system won’t switch on, you will need to call an AC repair team.

Completing spring maintenance on your AC system will help make sure your system is ready when it warms up outside.

Winter Indoor Air Quality

Winter Indoor Air Quality DenverDid you know that the air inside of your home can be more contaminated than the outside air? According to the Environmental Protection Agency, aka EPA, the air inside of your home has two to five times the pollution levels than outside air. If you’re like most Americans, you spend more than 90 percent of your day in the home, which is cause for concern when it comes to the air quality you’re breathing in majority of your day. During the winter, the air in your home could become even worse, read on to find out why and what you can do about it.

Why Winter Indoor Air Quality is Poorer

A lot of homes built today are made to be energy efficient. This means that windows and doors are sealed to keep outside air out and indoor air in. This is good for lowering your energy bill, but bad for your health, since the concentration of allergens and pollutants in your home becomes greater. During the winter, you don’t ventilate your home with open windows and doors.

Eliminating Common Household Pollutants

The best way to defend your household from pollutants is to identify and get rid of them. Here is a list of some of the things in your home that could be reducing the quality of your indoor air:

  • Oil burning appliances
  • Building materials and furnishings with VOCs
  • Household cleaning supplies and air fresheners
  • Paint
  • Animal dander and dust mites
  • Mold and mildew
  • Asbestos in paint or wood
  • Carbon monoxide
  • And more

It’s important to learn what your home and furnishings were made of, so that you can determine whether they are contaminated with toxins. Also make sure to clean any water damage in order to prevent fungal growths. Grand Home Services offers a range of products to help you improve your Denver indoor air quality in the winter and all year round.

Eliminate Condensation in Walls and Attics

It’s odd, but the air leaks that you find in most older homes can almost be seen as an advantage in one small way. Whereas drafty old homes will take in the lower humidity winter air, perfectly sealed newer homes sometimes experience problems from moisture generated by having much higher humidity air inside than out.

Don’t get us wrong. You want to prevent drafts to keep your heating and cooling costs down, but you also need to take some extra measures to avoid moisture problems. Without air leaks balancing the humidity inside and out, some newer homes may end up with condensation in walls and attics. This moisture can diminish the effectiveness of insulation and maybe even lead to dry rot in wood.

What can you do if you have condensation?


Properly ventilating your home with fans will go a long way toward helping you eliminate bad effects from moisture. The low cost solution would be to crack a window next to a bathroom or kitchen fan. If you want a more comprehensive solution, you should think about using an air to air heat exchanger to bring in fresh outside air through a ventilation system and warm it.

Seal Moisture

Crawlspace is a major source of condensation. With just plastic and heavy tape (or roofing tar), you can create a vapor seal that eliminates moisture from entering your home through its crawlspace.


If the problem is too much humidity inside, a dehumidifier is another great solution. These products are great for basements that are too cool in the summer or tightly sealed homes that are too humid in the winter. Dehumidifying will help you find that balance that will help you avoid damaging condensation in walls and attics.

End the moisture problem in your Denver home by contacting the experienced professionals at Grand Home Services. Our ventilation expertise and dehumidifying products can help you dry up any condensation issues.

Commercial HVAC Maintenance Checklist

Preventative HVAC maintenance is something that too often takes a low priority in a business’s budget. Unfortunately, most companies don’t realize how much money they are wasting by sitting back and waiting for things to go wrong instead of investing in a commercial HVAC service plan.

You don’t have to take our word for it that relying on reactive measures will increase the cost of your heating and cooling operations. According to a study done by the New Building Institute, not keeping up with routine, proactive maintenance can increase a company’s energy use by as much as 60 percent per year.

Check Commercial HVAC Equipment Twice a Year

Scheduling preventative HVAC maintenance in Denver will reduce your energy use significantly and help you catch minor problems before they lead to expensive repairs. In most cases, we recommend only two visits per year — once in the spring and once in the fall. By doing this, we can catch any issues before you get into peak usage months in the summer and winter.

Here’s a brief summary of the items that are checked in a routine service visit to a commercial property. The outdoor HVAC checklists differ from indoor HVAC checklists.

On outdoor units, we’ll check:

  • Refrigerant level
  • Fan motor and blades
  • Compressor and tubing
  • Oil and cabinet
  • Base pan drain opening
  • Control box, wiring and connections

Indoor unit inspections include:

  • Ductwork
  • Air filters
  • Fan belt
  • Blower assembly
  • Combustion blower housing
  • Condensate drain line, drain pain, and evaporator coil
  • Ignition system and safety controls
  • Heat exchanger or heating elements
  • Burner assembly
  • Flue system
  • Control box, wiring and connections

We will watch your HVAC equipment in action so we can complete an in-depth system operation report that includes recommended measures for improvement.

Avoiding costly emergency calls and repairs, and maintaining peak efficiency of your HVAC equipment should be a top priority. To save money and earn peace of mind, call 720-365-1187 and schedule a commercial HVAC service in Denver this fall.

Save on Energy Costs by Reducing Heat Gain

You may not be familiar with the phrase “heat gain,” but you at least probably know what it feels like. If you constantly find yourself turning your thermostat down due to your cooling system’s inability to cope with heat during peak hours, it’s likely that you’re dealing with a heat gain problem.

Air conditioners — even powerful units — can be overwhelmed by extra burdens produced by poor insulation, uncovered windows, and heat generating appliances. We have some easy tips for you to follow to avoid the discomfort and high utility bills that usually come with heat gain.

Check Insulation

Without adequate insulation, your home cannot defend against invading heat. Walls, floors, and attics all should meet the recommended resistance standard. Many factors can influence the recommended insulation resistance level (R-) for your home, but here are some baseline standards to consider: R-18 for exterior walls, R-25 for floors, and R-49 for attics. Think about adding more insulation if your home falls short of these standards.

Cover Windows

Curtains, awnings, blinds, and shades can be one of your best weapons against heat gain. If you combine them with light-colored window treatments, you could be looking at a significant reduction in your cooling costs.

Be Mindful of Appliances

You might be surprised by how much extra heat some appliances can produce. Because of this, clothes dryers, dishwashers, and similar appliances should be run sparingly during peak heat hours. Save them for nighttime use.

Seal Any Air Leaks

If your home has air leaks around doors or windows, you are definitely going to experience some heat gain. Caulk, weather stripping, and door sweeps can provide fast and easy solutions that save you big on energy costs.

Battle Heat Gain with Grand Home Services!

The heating and cooling experts at Grand Home Services can give you all kinds of advice on reducing the heat gain in your Denver home. For more tips, or to schedule maintenance on your air conditioner, contact us at (720) 365-1187.

3 Air Conditioner Maintenance Tips for DIYers

DIY Air Conditioning TipsAs summer reaches its apex and temperatures soar to the highest point they will reach all year, it is the perfect time to think about air conditioner maintenance. While many potential problems can be caught and solved by scheduling an annual AC checkup with a Grand Home Services technician, we also want you to know about some helpful DIY maintenance tips.

By following three simple DIY air conditioning tips, you can significantly increase your chances of maintaining peak A/ C performance even through the hottest days of the year.

1. Maintain Filters, Coils, Blades

By taking just a few minutes each month to clean air filters, coils, and blades, you can have a significant impact on the efficiency and reliability of your cooling system. It’s always best to consult the owner’s manual and turn off your system before attempting to clean or replace anything.

2. Clean Outdoor Units

Sometimes leaves, rubble, and other debris will accumulate on or around your air conditioner. Taking a moment to remove these items can have a surprisingly big impact on the overall health of your system. You can even combine tasks by cleaning debris at the same time as you clean your filters, coils, and blades.

3. Use Your Yard to Maximize Efficiency

If your cooling system receives proper shade from the sun, it can improve efficiency by up to 10 percent in the summer. However, that doesn’t mean you should place trees and shrubs right on top of your air conditioner. It’s best to keep all leaves, grass clippings, and other vegetation at least two feet away from your unit to prevent clogging from debris. Find the right setup that puts your unit in the shade for most of the day without adding the risk of too much debris.

These DIY air conditioning tips will help you overcome many of the problems that people typically experience during the summer months. If you ever have an issue that goes beyond a DIY repair, you can always turn to the heating and cooling experts at Grand Home Services.
