"Showed up late, didn't install the bathroom fan as the manufacturer recommended (pic, fan5), dented the fan grille (pic, fan1). It was installed without the supplied support rails because he claimed he couldn't get in the attic. Now sure how I got the photos, then... The vent hose was kinked in the attic and hardly any air came out of the soffit, so I had to go into the attic to correct it. That's when I took the photos. Didn't give a price up front because apparently a bath fan with bluetooth speakers isn't in whatever book they price from. Not in the book? Overcharge. Generally very unhappy with the whole experience and will be looking elsewhere in the future. Not sure how when the customer supplies EVERYTHING but a romex clamp someone can charge so much. Absolutely unacceptable. $465 to have someone dent my fan, install it incorrectly, and throw out the parts that weren't used. Like the battery to the manufacturer supplied remote and the joist supports. I'm leaving the cost of service as originally quoted because it was only lowered to $465 after I complained about being ripped off."

"I received six estimates for replacing my air conditioning system. Of the six, four came in at a reasonable price including the estimate from the Michael Bonsby Company. Three of the four estimators made a good impression but the one who impressed me the most was David Lux of Michael Bonsby. He spent the most time, provided the most information, and fully answered all of my questions in all of my contacts with him prior to signing the contract. Even after I signed the contract, had the system installed, and made final payment, David Lux was still very prompt in answering my inquiries. So far I am very happy with the air conditioning system installed by and I would highly recommend the Michael Bonsby Company if you ever need to replace your air conditioning system."

"The company was a pleasure to work with. The quality and professionalism was good. The scheduling was quick and on time. I saw the previous complaints posted, but did not have any problems. I received their name thru Angies List and did not get additional estimates as it was 100 degrees and wanted AC ASAP. We told them that the fan wasn't working and needed repaired. They said the fan motor had a computer chip or some type of computer part with it and that's not common. After testing our AC unit their results showed that the condenser showed a good life span remaining. We were thinking about getting a new unit, they said it was our call but thought a repair would be a good choice. The boss called us and went over their findings and discussed our options. We decided to go with the repair due to the economy and their recommendation. When they removed the old motor they saw that it had been set to medium speed. Since I had previously told them our house is not balanced properly, he set it to high . The only thing I didn't care for was we had to pay for the estimate up front, but the fee was lower than I had expected. When we went to have it fixed they wanted the money up front again. I have always been taught to never do this but to put a deposit it down and pay in full when the job is complete. I did pay upfront again and did not have any problems. I do feel the fee was on the high side but again, I didn't get any other estimates and the other companies probably would have talked me into a new unit. We will see how long this unit lasts. The day after work was performed I had not received a receipt or warranty paperwork. I called the office and explained my thoughts of billing to them and they listened. Before I hung up my paperwork had been emailed to me. I would recommend them. They did not add any Freon and our unit is keeping our home cooler than ever. Thank you At Your Service."

"Fantastic company from start to finish! The gentleman who sold us the furnace, their salesman, Alex, was upfront in getting us the best price, along with a 10 yr parts and labor warranty included! The price for the furnace and installation was great, and they guaranteed apples to apples to meet any other companies cost. They offer a $100. fee if we found anyone to do it cheaper, with the same offer. They were able to schedule the intallation quickly, and did a great job intalling it. I would highly recommend using this company for your heating and air conditioning needs. Great company! Great prices! Great work! You won't be disappointed using Horizon Services! Take care....."

FAQs for air conditioning projects in Phoenix, 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.
