Air Conditioning Repair &  Installation


A cool home in the heat of summer is a welcome escape. Have you ever wondered how an air conditioning system works? AC systems run off either gas or electricity, and they all function on the same basic principles. A furnace is required to distribute cooled air throughout your home via a natural gas air conditioner, while electric air conditioning systems utilize an air handler for distribution.

The system’s condenser is the AC unit you find outside your home. Inside this condenser sits a compressor, condenser coil, and large fan. Cool refrigerant pumps connect to an evaporator coil, which is found either in the building’s furnace or air handler. The location depends on whether it runs off gas or electricity. The furnace, or air handler blower, pushes warm air past the cold condenser coil to cool it. Then, this cool air is distributed throughout the structure via air ducts.

The evaporator coil absorbs heat and warms the coolant as it moves through. Next, warm refrigerant pumps back outside to the condenser to be cooled by the large fan. This causes the heat to escape into the outdoor air. The cycle continues until the indoor air temperature reaches that set on the thermostat.


The mechanisms that comprise your AC system depend on each other to function properly. Unfortunately, with repeated use, these parts can wear out. Coolant may leak, compressors malfunction, and air ducts may become polluted, break down or not be large enough to effectively deliver cool air throughout your home. Scheduled maintenance by the professionals at Gilk Services of Richmond, MN can keep your air conditioner in peak operating order. Contact us today to set up an appointment.

Maintenance plans are available to ensure that your HVAC system runs at optimal efficiency.


Have your energy bills spiked? Is the air in your home uncomfortably warm, despite turning down the thermostat? Your AC unit may be malfunctioning, even if it continues to run. Leaking refrigerant may cause the evaporator coil inside your furnace or air handler to freeze. If the evaporator coil freezes, it could seriously damage the coil. Monitor your outdoor condenser for leaks and pay attention for unusual noises as the air conditioning unit kicks on. If your AC is on the roof, be on the lookout for watermarks on your ceiling. For fast, expert and affordable air conditioning repair, contact Gilk Services today! We provide 24-hour emergency service.


If you’ve never had an AC unit in your home, or if your existing unit is a decade or more old, call us! A new air conditioning unit is typically integrated with your heating system. This means it most likely shares ductwork, blowers, temperature controls, and more. So, we must inspect your current heating and cooling system before making suggestions for a new unit or offering you an estimate. With our free in-home assessment, we can determine which of your existing components will adapt to new equipment, and which would cost less to replace. It may make sense to retrofit your current furnace to a new central air conditioner. You could even save the money you would spend on parts and labor and instead install a new HVAC unit. Ultimately, the choice is yours to make. But you can rest easy knowing that the Gilk Services experts in the Richmond area are here to help. Contact us today for more information!


Choosing the perfect air conditioning system for your home can be a daunting task. There are many factors to consider, such as the size of your home, the climate you live in, and your budget. A professional installer at Gilk Services can help you select the best system for your home and install it properly, ensuring that you get the most from your investment.

1. HVAC systems are a big investment—Gilk Services is here to help.

2. Know your priorities: what are your must-haves?

3. Get the right size system: too big and it will be inefficient, too small and it won’t keep up.

4. Consider your home’s layout: do you need a single or multi-zone system?

5. ENERGY STAR® certified systems may be slightly more expensive up front, but often save consumers 20% or more on their utility bills.

6. Think about installing a zone heating & cooling system in your home for added comfort and to help control energy costs.

7. Regular maintenance of your system will keep it running.

When it comes to your home’s comfort, heating and cooling (HVAC) systems are a big deal—and a big investment. With so many variables to consider, it’s important to do your research before purchasing an HVAC system. Our HVAC installation contractors are here to guide you through your cooling and heating system purchase and after! We want to ensure that you’re comfortable all year round and have an HVAC system that will last for years to come.

Always Start with a Home Energy Audit

Gilk Services can evaluate your home as a whole to recommend ways you can improve the comfort level of your space, lower bills, reduce emissions, and more! The recommendations will help tailor the size and design of your HVAC system exactly to what you need based on insulation levels, windows and doors, and air ductwork… You name it. Doing this at the start will save you frustration later on because choosing a heating or cooling unit cannot be done accurately without properly sealing leaks in your house first (could cost more than expected).
