Frequently Asked Air Conditioning Questions

My name is David Galan. Dennis Grimes and I have over 40 years’ experience repairing air conditioning systems in the College Station, Texas area. We have a lean strategy that keeps overhead low so you are sure to get quality service and top-notch products at a price you can afford. I put together a list of the most frequently asked questions we get asked all-year-round.

Do you have a question about air conditioning that we haven’t addressed here? Contact us and we’ll be happy to help!

A. Why We Charge a Diagnosis Fee for Repairs

We charge a diagnosis fee so we can afford to take our time properly diagnosing the scope of the repairs needed. We individually assess repairs so the resulting work order is custom to you suit your needs. Our diagnosis process, increases the accuracy of our repair work and reduces stress on the customer.

Our diagnosis fee for repairs includes:

  1. Travel time to and from the job site with our equipment
  2. Our expertise and the full amount of time it takes to prepare the custom diagnosis (range from 5 min to 1 hour)
  3. A custom quote prepared exclusively for you
  4. The opportunity to answer any questions you may have
  5. Once the estimate is prepared, we’ll offer a range of dates to schedule the work for completion. Most of the time we can fix the problem the same day.  If we need to order parts, we’ll let you know how quickly we can bring them in and when we can return to complete the job.

*Please note, we do not charge a fee to estimate new installations. To schedule an estimate for a new installation please contact us.

We charge $90 to diagnose the issue Monday-Friday 8am-5pm and $200 after hours or on the weekend.

New system estimates are FREE

C. How often should I get my air conditioner serviced?

At least once a year, but getting it serviced twice a year is ideal. Once in the fall before the heating season begins and once in the spring before the cooling season starts.

D. Is there anything I can check or do when things go wrong?

One simple thing to check is to make sure that you have good batteries in the thermostat. Otherwise, the best thing to do is turn the system off until a service tech can take a look at it. This will help protect the system from further damage from trying to run with one component not working.

E. What kind of filters should I use? How often should I change them?

We recommend changing filters once each month in the summer and up to three months in the winter. While high merv filters remove more dust and debris from the air, they also restrict airflow. This can lead to problems such as reduced energy efficiency, more wear and tear on the equipment, and a too cold air stream, which can cause mold growth on the vents and in the ducts. If you want better filtration, we recommend installing a 4 inch media filter cabinet directly before the air handler. These four inch filters can achieve better filtration without restricting airflow as much as an equivalent 1 inch filter.

F. Some bedrooms are always warmer than the others, is there any way to fix that?

Answer: In some cases the duct system is outdated or inadequate, in which case the way to correct it is to replace the duct system. In other cases it can be as simple as increasing the duct sizing to the warm bedroom or adding an intake.

G. Do you offer portable AC Units?

Courtesy portable AC units for use while jobs are being completed. These are offered at our discretion while quantities last. Ex. Waiting on a part or waiting for a new system to be installed.

Mr. Grimes delivered fast, friendly service in July! He didn't mind my standing about to see what they were doing - he encouraged it! He was punctual and attended to the job efficiently. As I overheard him and his coworker interacting, they spoke clearly and kindly to one another. I will definitely call Grimes and Galan for my next heating/air conditioning crisis! (Let's face it - it's a crisis when the AC goes out in Texas!)

Dennis was a welcomed change to the normal service personnel I have encountered within the past year. He is prompt, professional and competent. I have absolutely no reservations in recommending Dennis to anyone with a HVAC issue. I’m a small business owner myself and I can relate to the benefits of working with an owner/operator. It makes a real difference. Thank you Dennis for the prompt 9am service call. jeff

I purchased a new HVAC Carrier system 3 years ago from another local company. Each year (in the heat of the Summer) I've had the same reoccurring issue and kept with the same company afraid of voiding my manufacture warranty. It happened again this time I decided to try someone new and get a second opinion. I emailed Dennis Grimes and he promptly responded and fixed my issue immediately for 1/2 the cost of what I was paying the "other" company.  My new system was also making a very loud vibrating noise and I always thought it was off since it was new. I was told that's normal from the other company. Turns out Mr. Grimes noticed there was way too much Puron in my system so he adjusted it and now it runs quiet and I can hardly tell it's on. I highly recommend Dennis Grimes and recommend staying away from the bigger companies and keeping business local. It was more personable and he obviously knows his stuff. Huge lesson learned for me. Thanks Dennis Grimes and I will be referring your way without hesitation.

Our air conditioner stopped running effectively last week. It was in the middle of a heat wave so we needed someone to fix it ASAP. After calling a couple of places, we decided to have Dennis work on the conditioner. We couldn’t have been more pleased with our decision. Within minutes of inspecting our air conditioner he found the problem and was able to fix it within 24 hours at a very reasonable price. We are happy to say that the air conditioner now running smoothly. If you want to trusting, reliable, and affordable service, use this company – Thanks Dennis!

Wanted to say Fathers Day week-end and I went to visit my son in College Station and around 8-9pm Saturday evening the ac stopped working. I found three AC companies and contacted them all on the internet, an hour later Dennis Grimes emailed me and we set up a early morning appointment for fathers day! He was there found and fixed the problem within 1.5 hours. I never met Dennis as I returned home before he arrived but he has great communications and tells you what needs to be done, and acts like the money will be coming out of his pocket – he watches out for the customers and their money – thanks and I will be sure to always use his services!

I came home the evening of 8/23 around 7:30pm to discover that the central A/C in my house had stopped working. By the time I was able to start calling some local companies it was around 9pm; out of quite a few places I called at that hour, Dennis was one of two who answered. We were able to arrange an appointment for the following afternoon, and he was able to quickly make the relevant repairs. Very courteous and professional all around. Pricing was reasonable. All around, a positive experience. I particularly appreciate him making the effort to respond to a call at such a late hour.
