"This is an excellent company. We have used them for year to service our heating and air conditioning units. It became necessary to think about replacing the units. We have two. Decided to replace both at the same time. They came out on a Monday and gave us an estimate and came out on Thursday and Friday to do the work. They totally cleaned up after themselves and made sure everything was working properly. Then they called a few days later to see that everything was working well. I highly recommend this company. All the technicians are polite and competent. The office staff is nice beyond belief. If you need any heating/AC work done, this is the company to do it."

"Great response time! My A/C went out on a hot Friday night and was out on an even hotter saturday morning. He was there 1 hour after I called and had the part that needed to be replaced. He was very knowledgeable and shared great tips on how I can save money and have my unit last longer."

"Mr. Bost did an excellent job for me for a reasonable price. I know he obtained the best deal for me on the furnace and the air conditioning unit. He answered all my questions. He was on the job when he said he would be; he was professional and courteous. The installation went smoothly, and I have had no problem with the furnace or air conditioner since they were installed in 2008."

"I was experiencing low water flow to my 3rd floor bedroom. Since the house is 100 years old, I assumed that the only way to repair the problem was to replace the water service lines which would have been very expensive. Brian came to the house and identified the source of the problem as the water pressure regulator. Brian replaced the regulator, drained and refilled the lines to remove air bubbles. The problem was repaired. Given the age of the house and the location of the problem most contractors would have told me I needed to replace the pipes to the 3rd floor. Brian identified the real problem and in the process saved me a lot of money. Great Job."

"It went extremely well! He first came to survey what needed to done and to take measurements. After purchasing supplies, he promptly installed the new weatherstripping.

This project was a breeze. Scheduling and communication was smooth and pleasant. He explained what needed to be done and made sure I was pleased with the work.

Highly recommended!

FAQs for air conditioning projects in Boring, MD

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
