"My AC was blowing but not cold. Had McCrea stickers on my unit. Looked up in local phone book and called. Had an appointment 2 days later. Tech (Mario Cieza) called in the specified timeframe, 30 min before arrival. Tech was polite and direct to troubleshooting. I had AC issues 3 years ago and it was a bad compressor capacitor. Mario after troubleshooting diagnosed that the same capacitor was bad. He replaced the capacitor, checked and topped off the coolant, and cleaned the blower exterior. The quoted repair price was reasonable ($237). I was happy with the service response, professionalism and price."

"Holtzople installed our new ac/heating unit in 2021. The company and service has been fabulous from the beginning. Today we had our comfort care service of our main unit and split units. The service technician, Tim was punctual, professional and a diligent worker. He took care of both units, installed an air scrubber and leveled our outside unit. Great service technician and very knowledgeable. We continue to be very pleased with the service Holtzople provides for their products."

"Moises came out the same day that I requested an estimate for the installation of a UV light whole house air purification system, and to chemically clean my AC coil. I had another estimate but Moises gave me a better deal. He also recommended getting a cover for my AC unit for the winter, when he opened it up it was full of leaves and debris. I am very satisfied with the work that was done and would highly recommend MSR."

We are a small family owned Heating, Ventilation, and Air Conditioning (HVAC) company located in Sharpsburg, MD. The business was started in 1989 under the name of RW Harrell's Pump Service Inc. when Diane Harrell and Ronnie Harrell purchased a well pump and water system business from a gentleman that was retiring. Ronnie had worked in the HVAC field from the time he had graduated from high school so it was natural to add HVAC to the services that this new company would offer. Ronnie and Diane built the company by word of mouth and continue to grow the company in this manner. Additional DBA - Harrell's Services. Additional fax - 928-492-8004

"The sales rep was very attentive when coming over and designing a solution to our heat and air needs. We were able to get a large team of workers here and knocked out an entire house install in one day. Some trash and miscellaneous items were left in our yard. When we needed additional items from the sales rep he will respond back saying he will take care of it but still has not. I have brought this up to him over 4 times and I still get nothing. The price seemed pretty high, and we had to shop the price around some but the company came with good financing options and some guarantees that others could not. The mini-split units work great."

"The original job was to add 30 amp access outside of garage so I could plug in my RV. They fixed a breaker, updated the panel for the 30 Amp job and added GFI's to the panel for 4 areas. They were 2 for the kitchen, 1 for the pool, and 1 for the garage. Both electricians I dealt with were very professional and knowledgeable. The actual work was done quickly. He explained what he did and made future recommendations."

"Our dryer vents from the center of the house to just under the second story eves. He did a great job of cleaning it from both ends, and adjusted the dryer hose to an optimal length and resealed it with tape. Also cleaned vents well. I am very particular about mechanics, handymen, and service people. Mack's is on the short list of people I will hire again. The serviceperson was polite and personable as well as very competent. And, he took pains not to track up the carpets. Mack's is a good choice. You'll be satisfied w the results."

Air Conditioning FAQs, answered by experts

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.
