Upgrading Your HVAC? | HVAC Costs in 2020

There is a very wide margin in price ranges for new HVAC systems today. You can expect to pay anywhere from $5,000-$12,000 in 2020 for a complete heating and cooling system. Individual furnace or air con replacements will cost less, and this is sometimes an option. What factors affect the cost? There are a number of things, big and small, that contribute to the final cost – the size, location, and setup of the area to be covered, the brand and model of the system and its components, if ductwork installation will be necessary or not, and local labor costs.

Make the right choice and contact DM Select Services. A qualified professional will evaluate your home or workplace and assist you in choosing the ideal system for your particular needs. On a strict budget? Call us today at 301-265-3635 or visit our site to find out about our great payment options.


DM Select Services provides AC repairs throughout Maryland. Our customers come first, every single time. If you want a technician to check out your problem and solve the issue as soon as possible, then call us at 301-265-3635 today and schedule an appointment.

We provide AC repair services to both commercial and residential customers. The last thing you want is to be dealing with a failing air conditioner when summer is in full swing. However, AC services are not only provided in the hot summer months, but also in the cold months. If an AC is faulty, then freezing temps can be let into your office or home.

Air conditioning units that have leaks can cause temperatures to fluctuate. In turn, your electric bills can increase. It is crucial to ensure your AC is in optimal condition because this will ensure that the temperatures remain at a comfortable level. This will also keep your electric bill low.

Should I Upgrade My Air Con?

Do you have the AC repairman on speed dial these days? And maybe you’ve wondered if your utility provider is reading your meter wrong because the costs are steadily increasing? The fault may be your air conditioner. If your HVAC system is 10-15 years old, and particularly the AC unit, now is a good time to upgrade.

With the new heating and cooling technologies, replacing systems or components that are 10 or more years old could easily save you 20-40% on your energy bills. You can cut your utilities down by up to 40% by replacing an AC with an EER rating of 5 with an EER-10 rated one.

“Very impressed with DM Select. First impressions are important and the friendly receptionist answered the phone right away, and she had a technician to my place within a day or two. After getting several quotes on a new HVAC, I did choose to use DM. They arrived at the exact time scheduled and did a fantastic job with the installation. I will definitely use DM Select for any other service they offer.”
